ELECTRONIC CIRCUIT INSPECTION PROCEDURE
1.BASIC INSPECTION
(a)WHEN MEASURING RESISTANCE OF ELECTRONIC PARTS
(1)Unless otherwise stated, all resistance measurements are standard values measured 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
Text in Illustration
*a INCORRECT *b CORRECT
(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 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.
(c) CHECKING CONNECTORS

Pull Lightly |
(1)Checking when a connector is connected: Squeeze the connectors 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. Visually check for corrosion, metallic or foreign matter and water, and bent, rusted, overheated, contaminated or deformed terminals.
(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.
(d) CONNECTOR TERMINAL REPAIR METHOD
Text in Illustration
*a CORRECT *b 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 gold-plated (gold color), use a gold-plated female terminal; if it is silver-plated (silver color), use a silver-plated female terminal.
2. CHECK FOR OPEN CIRCUIT
(b) Check the resistance.
(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)WIRE HARNESS HANDLING
Text in Illustration
*a INCORRECT
(1)If removing a wire harness, check the wiring and clamps 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 any high temperature part, 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, repair it with insulating tape or replace the wire harness.
(a) For an open circuit in the wire harness in Fig. 1, measure the resistance and voltage as follows:
(1)Disconnect connectors A and C and measure the resistance between the terminals of the connectors.

|
|
|
If the results match the values specified above, a
short circuit exists between terminal 1 of connector B2 and terminal 1 of connector C.
4. CHECK AND REPLACE ECU
NOTICE:
The connector should not be disconnected from the ECU. Perform the inspection from the backside of the connector on the wire harness side.
When no measuring condition is specified, perform the inspection with the engine stopped and the ignition switch ON.
Check that the connectors are fully seated. Check for loose, corroded or broken wires.
(a) First, check the ECU ground circuit. If it is faulty, repair it. If it is normal, the ECU could be faulty. Temporarily replace the ECU with a normally functioning one and check if the symptoms occur. If the trouble symptoms disappear, replace the original ECU.
(1)Measure the resistance between the ECU ground terminal and body ground.

GENERAL INFORMATION
A large number of ECU controlled systems are used in this vehicle. 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 circuits one by one. An adequate understanding of the system and a basic knowledge of electricity is enough to perform effective troubleshooting, accurate diagnosis and necessary repairs.
(For using the Techstream*)
HINT:
*: The Techstream is the name for the diagnostic tester in North America.
Before using the Techstream, read the operator's manual thoroughly.
If the Techstream cannot communicate with the ECU controlled systems when connected to the DLC3 with the ignition switch ON and the Techstream turned on, there is a problem on the vehicle side or the Techstream side.
i.If communication is possible when the Techstream is connected to another vehicle, inspect the diagnosis data link line (bus (+) line), CANH and CANL lines, and the power circuits for the vehicle ECUs.
ii.If communication is still not possible when the Techstream is connected to another vehicle, the problem is probably in the Techstream itself. Perform the Self Test procedure outlined in the Techstream operator's manual.
1.TROUBLESHOOTING PROCEDURES
The troubleshooting procedures consist of diagnosis procedures for when a DTC is stored and diagnosis procedures for when no DTC is stored. The basic idea is explained in the following table.

DETAILS
The diagnosis procedure is based on the DTC that is stored.
The diagnosis procedure is based on problem symptoms.
TROUBLESHOOTING METHOD
The malfunctioning part is identified based on the DTC detection conditions using a process of elimination.
The possible trouble areas are eliminated one-by- one by use of the Techstream and inspection of related parts.
The malfunctioning part is identified based on the problem symptoms using a process of elimination. The possible trouble areas are eliminated one-by- one by use of the Techstream and inspection of related parts.
Vehicle systems are complex and use many ECUs that are difficult to inspect independently. Therefore, a process of elimination is used, where components that can be inspected
individually are inspected, and if no problems are found in these components, the related ECU is identified as the problem and replaced.
It is extremely important to ask the customer about the environment and the conditions present when the problem occurred (Customer Problem Analysis). This makes it possible to simulate the conditions and confirm the symptom. If the symptom cannot be confirmed or the DTC does not recur, the malfunctioning part may not be identified using the troubleshooting procedure, and the ECU for the related system may be replaced even though it is not defective. If this happens, the original problem will not be solved.
In order to prevent endless expansion of troubleshooting procedures, the troubleshooting procedures are written with the assumption that multiple malfunctions do not occur simultaneously for a single problem symptom.
To identify the malfunctioning part, troubleshooting procedures narrow down the target by separating components, ECUs and wire harnesses during the inspection. If the wire harness is identified as the cause of the problem, it is necessary to inspect not only the connections to components and ECUs but also all of the wire harness connectors between the component and the ECU.
2.DESCRIPTION
(a)The data of each system and Diagnostic Trouble Codes (DTCs) can be read from the Data Link Connector 3 (DLC3) of the vehicle. When the system seems to be malfunctioning, use the Techstream to check for malfunctions and perform repairs.
3.CHECK DLC3
(a) The vehicle ECUs use ISO 15765-4 communication protocol. The terminal arrangement of the DLC3 complies with SAE J1962 and matches the ISO 15765-4 format.
