Acura RL (1996-2004 year). Manual — part 651

NOTE:
• Before testing, go to the Troubleshooting Guide (see page

23-244

). Be sure to go through self-diagnosis function

modes 1 and 2 (see pages

23-248

and

23-252

).

• All connector views are from the wire side of female terminals unless otherwise noted.

1. Inspect the connector and socket terminals to be sure they are all making good contact.

• If the terminals are bent, loose or corroded, repair them as necessary, and recheck the system.
• If the terminals look OK, make the following input tests at the connector.

— If any test indicates a problem, find and correct the cause, then recheck the system.
— If all the input tests prove OK, the control unit must be faulty; replace it.
