PROCEDURES

(1) Turn the ignition key to the "LOCK" position, disconnect the negative battery cable and tape the terminal.

Caution: Wait at least 60 seconds after disconnecting the battery cable before doing any further work. The SRS system is designed to retain enough voltage to deploy the air bag even after the battery has been disconnected. Serious injury may result from unintended air bag deployment if work is done on the SRS system immediately after the battery cable is disconnected.

(2) Remove the rear console assembly.
(3) Release the lock of SDU connector in accordance with the following procedure:

In case that there is no notch on the lock lever (Type 1)

Place a flat tip screwdriver against the lock spring (metal section) of the connector lock lever as shown in the illustration, and push the spring horizontally toward the inside of the unit.

Caution:
1. Do not use excessive force to raise the lock lever.
2. Do not insert the screwdriver into the gap between the lock lever and the lock spring.

In case that there is a notch on the lock lever (Type 2)

Place a flat tip screwdriver against the lock spring (metal section) at the lock lever notch as shown in the illustration, and push the spring toward the unit.

Caution: Do not use excessive force to raise the lock lever.

(4) Disconnect the red 14-pin connector from the SDU.

(5) Connect the now disconnected red harness-side SDU connector (14-pin) to the connector (3) of the SRS Check Harness.

(6) Check according to the flow chart on the next page, using the specified digital multi-meter.

NOTE - IMPORTANT:
(1) After repairing the SRS, reconnect the battery cable, erase the diagnostic trouble code memory from the scan tool (1992 model) and check the SRS warning light operation to verify the system functions properly. Refer to TEST 1. Test 1 - SRS Warning Light Does Not Extinguish
