Indicator Input Test

Indicator Input Test

CAUTION:

• All SRS electrical wiring harnesses are covered with yellow outer insulation.
• Replace the entire affected SRS harness assembly if it has an open circuit or damaged wiring.
• Before disconnecting the SRS wiring harness, turn the ignition switch off, disconnect the negative and positive battery cables, and wait at least three minutes.

1. Remove the gauge assembly and disconnect all connectors from it.
2. Inspect the connector and socket terminals to be sure they are 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 30 – P connector.

• – If a test indicates a problem, find and correct the cause, then recheck the system.
• – If all the input test prove OK, but the indicator is faulty, replace the main printed circuit board.

1. A 30 – P connector
2. B Gauge assembly
