2. FOR VEHICLES EQUIPPED WITH SRS AIRBAG AND SEAT BELT PRETENSIONER
The CAMRY is equipped with a Supplemental Restraint System (SRS).
CAUTION: Failure to carry out the service operations in the correct sequence could cause the SRS to unexpectedly deploy during servicing and lead to serious injury. Furthermore, if a mistake is made when servicing SRS, it is possible that the SRS may fail to operate properly. Before servicing (including removal or installation of parts, inspection or replacement), be sure to read the following section carefully.
(a) GENERAL NOTICE
(1) As malfunctions of the SRS are difficult to
confirm, the Diagnostic Trouble Codes (DTCs) become the most important source of information when troubleshooting. When troubleshooting the SRS, always check the DTCs before disconnecting the battery.
INTRODUCTION – REPAIR INSTRUCTION
(2) Work must be started at least 90 seconds after
the ignition switch is turned off and after the cable is disconnected from the negative (-) battery terminal. The SRS is equipped with a back-up power source. If work is started within 90 seconds af ter turning the ignition switch off and disconnecting the cable from the negative (-) battery terminal, the SRS may deploy. When the cable is disconnected from the negative (-) battery terminal, clock and audio system memory is erased. Before starting work, make a note of the settings of each memory system. When work is finished, reset the clock and audio system as before.
CAUTION: Never use a back-up power source (battery or other) to avoid erasing the system memory. The back-up power source may inadvertently power the SRS and cause it to deploy.
(3) In minor collisions where the SRS does not
deploy, the steering pad, front passenger airbag assembly, driver side knee airbag assembly, front seat side airbag assembly, curtain shield airbag assembly and front seat outer belt assembly should be inspected before further use of the vehicle. (See page RS-352 for steering pad) (See page RS-399 for front passenger airbag assembly) (See page RS-371 for driver side knee airbag assembly) (See page RS-432 for front seat side airbag assembly) (See page RS-426 for curtain shield airbag assembly) (See page SB-23 for front seat outer belt assembly)

HOW TO TROUBLESHOOT ECU CONTROLLED SYSTEMS
GENERAL INFORMATION
IN
A large number of ECU controlled systems are used in the CAMRY. In general, ECU controlled systems are considered to be very intricate, requiring a high level of technical knowledge to troubleshoot. However, most problem checking procedures only involve inspecting the ECU controlled system's circuits one by one. An adequate understanding of the system and a basic knowledge of electricity is enough to perform effective troubleshooting, accurate diagnoses and necessary repairs. FOR USING INTELLIGENT TESTER – Before using the intelligent tester, read the tester
operator's manual thoroughly.
– If the tester cannot communicate with the ECU controlled
systems when the tester is connected to the DLC3 with the ignition switch on and the tester turned on, there is a problem on the vehicle side or tester side. (1)If communication is normal when the tester is
connected to another vehicle, inspect the diagnosis data link line (Bus (+) line) or ECU power circuit of the vehicle.
(2)If communication is still not possible when the tester is
connected to another vehicle, the problem is probably in the tester itself. Perform the Self Test procedures outlined in the tester operator's manual.
INTRODUCTION – HOW TO TROUBLESHOOT ECU CONTROLLED SYSTEMS
ELECTRONIC CIRCUIT INSPECTION PROCEDURE
1. BASIC INSPECTION
(a) WHEN MEASURING RESISTANCE OF
ELECTRONIC PARTS (1) Unless otherwise stated, all resistance
measurements should be made at an ambient temperature of 20°C (68°F). Resistance measurements may be inaccurate if measured at high temperatures, i.e. immediately after the vehicle has been running. Measurements should be made after the engine has cooled down.
(b) HANDLING CONNECTORS
(1) When disconnecting a connector, first squeeze
the mating connector housing halves tightly together to release the lock, and then press the lock claw and separate the connector.
(2) When disconnecting a connector, do not pull on
the harnesses. Grasp the connector directly and separate it.
(3) Before connecting a connector, check that there
are no deformations, damage, looseness or
INCORRECT
INCORRECT
CORRECT
D032092E01
missing terminals.
(4) When connecting a connector, press firmly until
it locks with a "click" sound.
(5) If checking a connector with a TOYOTA
electrical tester, check the connector from the backside (harness side) using a mini test lead.
NOTICE:
As a waterproof connector cannot be checked from the backside, check it by connecting a sub-harness.
Do not damage the terminals by moving the inserted tester needle.

D025087E03
(c) CHECKING CONNECTORS
(1) Checking when a connector is disconnected:
Squeeze the connector together to confirm that they are fully connected and locked.
(2) Checking when a connector is disconnected:
Check by pulling the wire harness lightly from the backside of the connector. Look for unlatched terminals, missing terminals, loose crimps or broken conductor wires. Check visually for corrosion, metallic or foreign matter and water, and bent, rusted, overheated, contaminated, or deformed terminals.

IN–42
CORRECT
INTRODUCTION – HOW TO TROUBLESHOOT ECU CONTROLLED SYSTEMS
(3) Checking the contact pressure of the terminal:
Prepare a spare male terminal. Insert it into a female terminal, and check for ample tension when inserting and after full engagement.
NOTICE: When testing a gold-plated female terminal, always use a gold-plated male terminal.
D025088E02
(d) REPAIR METHOD OF CONNECTOR TERMINAL
INCORRECT
(1) If there is any foreign matter on the terminal,
clean the contact point with compressed air or a cloth. Never rub the contact point using sandpaper as the plating may come off.
(2) If there is abnormal contact pressure, replace
the female terminal. If the male terminal is gold­plated (gold color), use a gold-plated female terminal; if it is silver-plated (silver color), use a
D032093E01
silver-plated female terminal.
(3) Damaged, deformed, or corroded terminals
should be replaced. If the terminal does not lock into the housing, the housing may have to be replaced.

(e) HANDLING OF WIRE HARNESS
(1) If removing a wire harness, check the wiring and
clamping before proceeding so that it can be restored in the same way.
(2) Never twist, pull or slacken the wire harness
more than necessary.
(3) The wire harness should never come into
contact with a high temperature part, or rotating, moving, vibrating or sharp-edged parts. Avoid contact with panel edges, screw tips and other sharp items.
(4) When installing parts, never pinch the wire
harness.
(5) Never cut or break the cover of the wire harness.
If it is cut or broken, replace it or repair it with vinyl tape.
2. CHECK FOR OPEN CIRCUIT
(a) For an open circuit in the wire harness in Fig. 1, the
resistance or voltage, as described below.

2. CUSTOMER PROBLEM ANALYSIS
IN
IN–48
INTRODUCTION – HOW TO TROUBLESHOOT ECU CONTROLLED SYSTEMS
HINT:
In troubleshooting, confirm that the problem symptoms
have been accurately identified. Preconceptions should be discarded in order to make an accurate judgment. To clearly understand what the problem symptoms are, it is extremely important to ask the customer about the problem and the conditions at the time the malfunction occurred.
Gather as much information as possible for reference.
Past problems that seem unrelated may also help in some cases.
The following 5 items are important points in the problem
analysis:
What Vehicle model, system name When Date, time, occurrence frequency Where Road conditions Under what conditions? Running conditions, driving conditions, weather conditions How did it happen? Problem symptoms
3. SYMPTOM CONFIRMATION AND DIAGNOSTIC TROUBLE CODE
HINT: The diagnostic system in the CAMRY has various functions.
The first function is the Diagnostic Trouble Code
(DTC) check. A DTC is a code stored in the ECU memory whenever a malfunction in the signal circuits to the ECU occurs. In a DTC check, a previous malfunction's DTC can be checked by a technician during troubleshooting.
Another function is the Input Signal Check, which
checks if the signals from various switches are sent to the ECU correctly. By using these functions, the problem areas can be narrowed down and troubleshooting is more effective. Diagnostic functions are incorporated in the following system in the CAMRY.

INTRODUCTION – HOW TO TROUBLESHOOT ECU CONTROLLED SYSTEMS
In the DTC check, it is very important to determine
whether the problem indicated by the DTC either: 1) still occurs, or 2) occurred in the past but has returned to normal. In addition, the DTC should be compared to the problem symptom to see if they are related. For this reason, DTCs should be checked before and after confirmation of symptoms (i.e., whether or not problem symptoms exist) to determine current system conditions, as shown in the flowchart below.
Never skip the DTC check. Failing to check DTCs
may, depending on the case, result in unnecessary troubleshooting for systems operating normally or lead to repairs not related to the problem. Follow the procedures listed in the flowchart in the correct order.
The following flowchart shows how to proceed with
troubleshooting using the DTC check. Directions from the flowchart will indicate how to proceed either to DTC troubleshooting or to the troubleshooting of each problem symptom.

The problem still occurs in a place other than the diagnostic circuit (the DTC displayed first is either for a past problem or a secondary problem).
4. SYMPTOM SIMULATION
HINT: The most difficult case in troubleshooting is when no problem symptoms occur. In such a case, a thorough problem analysis must be carried out. A simulation of the same or similar conditions and environment in which the problem occurred in the customer's vehicle should be carried out. No matter how much skill or experience a technician has, troubleshooting without confirming the problem symptoms will lead to important repairs being overlooked and mistakes or delays.
For example:
With a problem that only occurs when the engine is cold or as a result of vibration caused by the road during driving, the problem can never be determined if the symptoms are being checked on a stationary vehicle or a vehicle with a warmed-up engine. Vibration, heat or water penetration (moisture) are difficult to reproduce. The symptom simulation tests below are effective substitutes for the conditions and can be applied to a stationary vehicle. Important points in the symptom simulation test:
IN
IN–52
Shake Slightly
Vibrate Slightly
INTRODUCTION – HOW TO TROUBLESHOOT ECU CONTROLLED SYSTEMS
In the symptom simulation test, the problem symptoms as well as the problem area or parts must be confirmed. First, narrow down the possible problem circuits according to the symptoms. Then, connect the tester and carry out the symptom simulation test, judging whether the circuit being tested is defective or normal. Also, confirm the problem symptoms at the same time. Refer to the problem symptoms table for each system to narrow down the possible causes.
(a) VIBRATION METHOD: When a malfunction seems
to occur as a result of vibration. (1) PART AND SENSOR
Vibrate Slightly
Apply slight vibration with a finger to the part of the sensor suspected to be the cause of the problem, and check whether the malfunction occurs.
NOTICE: Applying strong vibration to relays may open relays.
(2) CONNECTORS
Slightly shake the connector vertically and horizontally.
(3) WIRE HARNESS
Slightly shake the wire harness vertically and horizontally. HINT: The connector joint and fulcrum of the vibration are the major areas that should be checked thoroughly.
(b) HEAT METHOD: When a malfunction seems to
occur when the area in question is heated. (1) Heat the component that is the possible cause of
the malfunction with a hair dryer or similar device. Check if the malfunction occurs.
NOTICE:
B071602E03
Do not heat to more than 60°C (140°F). Exceeding this temperature may damage the components.
Do not apply heat directly to the parts in the ECU.
D025085E02
(c) WATER SPRINKLING METHOD: When a
malfunction seems to occur on a rainy day or in high-humidity. (1) Sprinkle water onto the vehicle and check if the
malfunction occurs.
NOTICE:
Never sprinkle water directly into the engine compartment. Indirectly change the temperature and humidity by spraying water onto the front of the radiator.
Never apply water directly onto the electronic components.
INTRODUCTION – HOW TO TROUBLESHOOT ECU CONTROLLED SYSTEMS
IN–53
HINT: If the vehicle has or had a water leakage problem, the leakage may have damaged the ECU or connections. Look for evidence of corrosion or short circuits. Proceed with caution during water tests.
(d) HIGH ELECTRICAL LOAD METHOD: When a
malfunction seems to occur when an electrical load is excessive. (1) Turn on the heater blower, headlight, rear
