Initial SRS Diagnostic Procedure
WARNING: This page is about a different car, the 1995 Mitsubishi Galant. However, it is still accessible from the selected car via links, so may be relevant.
WARNING:
Read and understand all air bag service precautions to prevent accidental air bag deployment and personal injury. See SERVICE PRECAUTIONS
.
NOTE:
Ensure fuses No. 11 and 18 are okay. See Figure
. Ensure battery is fully charged. If battery voltage is too low, SRS warning light will come on. When battery voltage is restored to normal, light will go out. Codes remain stored for no more than about 7 days. Codes can be stored no more than 250 times. After servicing, reconnect negative battery cable. Erase codes using Multi-Use Tester II (MUT-II,MB991502). Check SRS warning light to verify system operation. See SYSTEM OPERATION CHECK
.
CAUTION:
Ensure ignition is off before connecting or disconnecting MUT-II at Data Link Connector (DLC). SDU connector is a double-locking mechanism. DO NOT
use excessive force when disconnecting SDU connector.
- Before proceeding, read and understand all air bag service precautions. See SERVICE PRECAUTIONS . Turn ignition on. If SRS warning light comes on for about 7 seconds and then turns off, SRS is functioning properly. If SRS warning light does not come on, or comes on and stays on, insert Read Only Memory (ROM) Pack into MUT-II.
- Turn ignition switch to LOCK position. Connect MUT-II to DLC. See Figure . Turn ignition on. If MUT-II does not display CAN'T COMM, go to step 4).
- If MUT-II displays CAN'T COMM, try to communicate with other systems (engine control, etc.). If MUT-II cannot communicate with other systems, see MUT-II CANNOT COMMUNICATE WITH OTHER SYSTEMS . If the MUT-II can communicate with the other systems, proceed to the MUT-II CAN COMMUNICATE WITH OTHER SYSTEMS test.
- Use MUT-II to retrieve code(s). Record code(s) and service data (fault duration and how many times memory was erased). Go to appropriate CODE procedure.
