Indicator Input Test

Indicator Input Test
SRS components are located in this area. Review the SRS component locations, and the precautions and procedures before performing repairs or service.
1. If the MIL has been reported, check for a DTC, and repair the system as indicated by DTC.
2. If the MIL does not come on, and the A/T gear position indicator P, N, or R does not come on, remove the gauge assembly from the dashboard, then disconnect gauge assembly connector A (30P).
3. Inspect the connectors and connector terminals to be sure they are making good contact.
4. If the terminals are bent, loose, or corroded, repair them as necessary, and recheck the system.
5. Turn the ignition switch ON (II).





6. Shift to the P position, and check for voltage between A2 terminal (BLK/BLU) and ground. There should be 0 V in the P position. There should be battery voltage in any other shift lever position. If the test results are different, check for a faulty transmission range switch or an open in the wire.
7. Shift to the R position, and check for voltage between A6 terminal (WHT) and ground. There should be 0 V in the R position. There should be battery voltage in any other shift lever position. If the test results are different, check for a faulty transmission range switch or an open in the wire.
8. Shift to the N position, and check for voltage between A1 terminal (BLK/RED) and ground. There should be 0 V in the N position. There should be battery voltage in any other shift lever position. If the test results are different, check for faulty transmission range switch or an open in the wire.





9. Check for voltage A14 terminal (YEL) and ground with the ignition in switch ON (II). There should be battery voltage. If the test result is different, check for a blown No. 10 (7.5 A) fuse in the under-dash fuse/relay box or an open in the wire
10. Turn the ignition switch OFF, and check for continuity between A30 terminal (BLK) and ground under all conditions. There should be continuity. If the test result is different, check for a poor ground (G502) or an open in the wire.
11. If all input tests prove OK, but the indicator is faulty, replace the printed circuit board.
