Suspension Warning Indicator: Service and Repair

Harness Connector Faces:

The error codes can be cleared by grounding the diagnostic enable circuit (pin C to pin A of the ALDL connector or pin D2 to D16 of the control module connector) three times (for approximately one second duration each) within 30 seconds. The control module indicates codes clear by turning the error lamp off for one second. The codes are not cleared when the battery or control module connectors are disconnected.

When error codes are cleared, the ignition cycle counter is disabled until the control module completes a successful self-test. A code 31 (Lift / Dive Error) requires a cycle of the ignition switch to retest.
