Turn ignition on. ABS warning light should come on as ABS goes into self-diagnostic mode. Read and record all diagnostic output (trouble) codes from ECU memory. Refer to Multi-Use Tester (MUT) manufacturer's instructions for specific trouble code retrieval procedure.
After all trouble codes have been retrieved and recorded, clear codes from ECU memory. Refer to Multi-Use Tester (MUT) manufacturer's instructions for specific trouble code clearing instructions. Recheck ECU memory to ensure all trouble codes were cleared. Refer to appropriate TROUBLE CODE DEFINITIONS (ECLIPSE) table or TROUBLE CODE DEFINITIONS (STEALTH & 3000GT) table and appropriate CODE under DIAGNOSIS & TESTING for servicing procedure.
If trouble codes cannot be cleared, ECU is currently detecting a malfunction. If codes can be cleared, problem is either intermittent or only appears while driving.
