Indicator Input Test
SRS components are located in this area. Review the SRS component locations (see COMPONENT LOCATION INDEX ), and the precautions and procedures (see PRECAUTIONS AND PROCEDURES ) before performing repairs or service.
- If the MIL has been reported, check for a DTC, and repair the system as indicated by DTC.
- 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).
- Inspect the connectors and connector 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.
- Turn the ignition switch ON (II).
- 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.
- 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.
- 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.
- 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.
- 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.
- If all input tests prove OK, but the indicator is faulty, replace the gauge assembly.
