USING CHECK HARNESS

  1. When checking voltage and resistance at ECM connector terminals, use Check Harness (SST 09990-01000, also called Check Harness "A") to prevent damaging terminals. (Scheme 18)
  2. To connect check harness, disconnect ECM connectors. ECM is located underneath top of passenger-side carpet (behind glove box) and is mounted to floor panel. Connect the check harness between ECM and harness connectors.
  3. Connectors and terminals on check harness match those of ECM. Wire colors that are specified in procedures apply to ECM connectors, but may not apply to check harness connectors. To identify connectors and terminals, see appropriate illustration under «CONNECTOR IDENTIFICATION»(ref-22039-S10495454552001010300000).
