Component Tests and General Diagnostics

Control Unit Input Test:

CAUTION:
^ All SRS wire harnesses are covered with yellow insulation. Before you disconnect any part of an SRS wire harness, disconnect the airbag connectors.
^ Whenever the ignition switch ON (II), or has been turned OFF for less than three minutes, be careful not to bump the SRS unit; the airbags could accidentally deploy and cause damage or injuries.
^ For additional precautions, refer to Air Bag and Seat Belts.

1. Remove the dashboard lower cover and knee bolster.
2. Disconnect the 14-P connector from the control unit

Control Unit Input Test:

3. 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.
