Sensing and Diagnostic Module: Technician Safety Information

Check vehicle body, forward (discriminating) sensor and SDM, and if any one of following symptoms is applicable, replace.

Sensor or SDM is in the area of accident damage.The "area of accident damage" is defined as that area of the vehicle which is crushed, bent, or damaged in other ways.An example might be a significant front-end collision in which the forward portions of the vehicle have contacted another vehicle, tree, guardrail, etc. Inthis example, a sensor on the front of the vehicle, such as the hood lock member, would require replacement, since that portion of the vehicle wasdamaged in the accident. A SDM in the passenger compartment would not require mandatory replacement. Of course, if the SDM sets a diagnostictrouble code and the diagnostic chart leads to a malfunctioning sensor or SDM that was not in the area of accident damage, that sensor or SDM shouldalso be replaced.Sensor or SDM in the area of accident damage should be replaced even if it does not appear to be damaged. Do not attempt to determine whether asensor or SDM is OK-ALWAYS replace it if it is in the area of accident damage.Also, if a sensor or SDM is in an area of accident damage, but the air bag system has NOT been deployed, replace the sensor or SDM. The sensor orSDM bracket may be slightly bent, wiring may be damaged, etc., and the sensor or SDM might not work properly in another collision. Again, do notattempt to determine whether a sensor or SDM is OK-ALWAYS replace it if it is in the area of accident damage.
An external damage such as deformation, scratch, crack, peeled paint, etc. is found through visual appearance check of sensor and SDM.

Sensor or SDM cannot be installed properly due to a cause in itself. (There is a gap between sensor or SDM and its mounting bracket, or it cannot befixed securely.)
Connector or lead wire of sensor or SDM has a scorching, melting or damage, or connector cannot be connected securely or locked.

SDM sets a diagnostic trouble code and the diagnostic chart leads to a malfunctioning sensor or SDM.

Sensor or SDM has been dropped from a height of or more.91.4 cm (3 ft)

Sensing and Diagnostic Module: Vehicle Damage Warnings
Air Bag System

Do not apply power to the air bag system unless all components are connected or a diagnostic chart requests it, as this will set a diagnostic trouble code.

The "Air Bag Diagnostic System Check" must be the starting point of any air bag diagnostics. The "Air Bag Diagnostic System Check" will verifyproper "AIR BAG" warning lamp operation and will lead you to the correct chart to diagnose any air bag malfunctions. Bypassing these procedures mayresult in extended diagnostic time, incorrect diagnosis, and incorrect parts replacements.

91.4 cm (3 feet)

When handling the air bag (inflator) modules (driver and passenger), forward (discriminating) sensor or SDM, be careful not to drop it or apply animpact to it. If an excessive impact was applied (e.g., dropped from a height of or more.), never attempt disassembly or repair butreplace it with a new one.
Never use air bag component parts from another vehicle.

When servicing, if shocks may be applied to air bag system component parts, remove those parts beforehand.
When using electric welding, be sure to disconnect air bag (inflator) module connectors (driver and passenger) respectively.
Never expose air bag system component parts directly to hot air (drying or baking the vehicle after painting) or flames.
WARNING/CAUTION labels are attached on each pant of air bag system components. Be sure to follow the instructions.

SDM
WARNING: Never power up air bag system when SDM is not rigidly attached to the vehicle. Otherwise, personal injury may result.

Never attempt disassembly of SDM.

When storing SDM, select a place where neither high temperature nor high humidity is anticipated and oil, water and dust are kept off.

If SDM was dropped from a height of or more or if it is found to be damaged or deformed, replace it with a new one.91.4 cm (3 ft)

Sensing and Diagnostic Module: Description and OperationComponent Description

SENSING AND DIAGNOSTIC MODULE (SDM)

WARNING: During service procedures, be very careful when handling a Sensing and Diagnostic Module (SDM). Never strike or jar the SDM.Never power up the air bag system when the SDM is not rigidly attached to the vehicle. All SDM and mounting bracket fasteners must becarefully torqued to ensure proper operation of the air bag system. The SDM could be activated when powered while not rigidly attached to thevehicle which could cause deployment and result in personal injury.

The Sensing and Diagnostic Module (SDM) is designed to perform the following functions in the air bag system:

1. Energy Reserve The SDM maintains a reserve energy supply to provide deployment energy when ignition voltage is lost in a frontal crash.2. Frontal Crash Detection - The SDM monitors vehicle velocity changes to detect frontal crashes which are severe enough to warrant deployment.3. Air Bag Deployment - When a frontal crash of sufficient force is detected, the SDM will cause enough current to flow through the air bag
(inflator) modules to deploy the air bags.

4. Malfunction Detection - The SDM performs diagnostic monitoring of the air bag system electrical components and sets a diagnostic trouble code
when a malfunction is detected.

5. Malfunction Diagnosis

- The SDM displays air bag diagnostic trouble codes and system status information through the use of special tool (Tech-1, scan tool).

- The SDM provides air bag diagnostic trouble codes by flashing "AIR BAG" warning lamp when on-board diagnosis function is used.

6 Driver Notification - The SDM warns the vehicle driver of air bag system malfunctions by controlling the "AIR BAG" warning lamp.

"ON" "ON"

The SDM is connected to the air bag wiring harness by a 12-way connector. This harness connector uses a shorting bar across certain terminals in thecontact area. This shorting bar connects the "AIR BAG" warning lamp to ground when the SDM harness connector is disconnected.This will cause the "AIR BAG" warning lamp to come steady whenever the ignition switch is at the or START position with the SDMdisconnected.

Sensing and Diagnostic Module: Description and OperationSystem Description

30 degrees

The air bag system consists of the Sensing and Diagnostic Module (SDM), the forward (discriminating) sensor, the driver air bag (inflator) module, thecontact coil assembly, the passenger air bag (inflator) module and the "AIR BAG" warning lamp in the instrument cluster. The SDM, contact coilassembly (driver side only), driver air bag (inflator) module, passenger air bag (inflator) module and connector wires makeup the deployment loops. Thefunction of the deployment loops is to supply current through the air bag (inflator) modules, which will cause deployment of the air bags in the event of afrontal crash of sufficient force, up to off the centerline of the vehicle. The air bag (inflator) modules are only supplied enough current todeploy when the SDM or the SDM and the forward (discriminating) sensor detect vehicle velocity changes severe enough to warrant deployment.

The SDM contains a sensing device which converts vehicle velocity changes to an electrical signal. The electrical signal generated is processed by theSDM and then compared to a value stored in memory. When the generated signal exceeds the stored value, additional signal processing is performed andthe generated signals are compared to signals stored in memory. When two of the generated signals exceed the stored values or when one of thegenerated signals exceeds the stored value and the forward (discriminating) sensor closes, the SDM will cause current to flow through the air bag(inflator) modules deploying the air bags.

Diagnostic Chart

CHART TEST DESCRIPTION:

Number(s) below refer to circled number(s) on the diagnostic chart.

1. An improper connection to the data link connector will prevent communications from being established.2. This test checks for an open in the "Serial Data" circuit.

3. This test checks whether an abnormality is in SDM or in any other part. Once the integrity of the "Serial Data" circuit including proper
connections has been confirmed and ABS control module can communicate, the SDM must be malfunctioning.

4. This test check for a short to ground in the "Serial Data" circuit.5. This test checks for a short to B+ or other power circuit in the "Serial Data" circuit.6. This test checks whether the malfunction is caused by a short in ABS control module (if equipped). With ABS control module disconnected from
"Serial Data" circuit, if SDM and the scan tool can communicate, ABS control module may be malfunctioning. Once the integrity of the "SerialData" circuit including proper connections has been confirmed and SDM cannot communicate, the SDM must be malfunctioning.

Wiper Relay: Description and Operation
INTERMITTENT WIPER RELAY CIRCUIT

ON
ON

When the wiper switch is set to the intermittent position with the ignition switch (the condenser is charged at this time), current from the batteryflows through the Y/BI wire, generates magnetic force in the coil in the relay and causes the switch in the relay to turn . Then current is transmitted inthe sequence of Y/BI, BI/W, wiper switch and BI, and causes the wiper motor to rotate (meanwhile, the condenser discharges). By the time the wipermotor makes one rotation and the contact plate in the motor comes to the automatic stop position P(1),the condenser in the relay has finished discharging(no magnetic force in the coil in the relay). Then the switch in the relay turns and the wiper stops.OFF

ON

They remain that way until the condenser is fully charged. As soon as the condenser begins discharging after being fully charged, magnetic forcegenerated in the coil in the relay causes the switch to turn . As described above, intermittent operation of the wiper motor is controlled by chargingand discharging of the condenser.
