Indicator Input Test

SRS components are located in this area. Review the SRS component locations, precautions, and procedures in the SRS section before performing repairs or service. See AIR BAG RESTRAINT SYSTEM .

1. Remove the gauge assembly from the dashboard. See Gauge Assembly Replacement , then disconnect the A (30P) and C (14P) connectors from the gauge assembly.
2. Inspect the connectors and connector terminals to be sure they are making good contact.
3. If the terminals are bent, loose, or corroded, repair them as necessary, and recheck the system.
4. Perform the following input test at the gauge assembly A (30P) and C (14P) connectors.
