- 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. See TROUBLE CODE DEFINITION and appropriate CODE under DIAGNOSIS & TESTING for servicing procedure.
