Indicator Input Test
WARNING: This page is about a different variant/trim than selected.
- If the D indicator or MIL has been reported on, check for a DTC, and repair the system as indicated by the DTC.
- If the D indicator does not come on, and the A/T gear position indicator light does not come on, remove the gauge assembly from the dashboard, then disconnect the gauge assembly connectors B (22P) and C (10P).
- 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.
- Shift to the P position, and check for continuity between C1 terminal (BLU/BLK) and ground. There should be continuity in the P position and no continuity 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.
- Turn the ignition switch ON (II), and shift to the R position by pressing the brake pedal. Check for voltage between C2 terminal (WHT) and ground. There should be 0 V in the R position, and about 5 V in any other 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 continuity between C3 terminal (RED/BLK) and ground. There should be continuity in the N position and no continuity in any other position. If the test results are different, check for a faulty transmission range switch or an open in the wire.
- Shift to the D position, and check for voltage between C10 terminal (GRN/BLK) and ground. There should be battery voltage in the D position, and 5 V in any other position. If the test results are different, check for faulty transmission range switch and TCM, or an open in the wire.
- Shift to the L position, and check for voltage between C4 terminal (BLU) and ground. There should be 0 V in the L position, and about 5 V in any other position. If the test results are different, check for a faulty transmission range switch or an open in the wire.
- Shift to the D position and check for voltage between B1 terminal (LT GRN) and ground. There should be 10 V while pressing the S mode switch and 0 V when the switch is released. If the test results are different, check for a faulty mode switch and TCM, or an open in the wire.
- Check for voltage between the B8 terminal (YEL) and ground. There should be battery voltage. If the test result is different, check for a blown No. 6 (7.5 A) fuse in the under-dash fuse/relay box or an open in the wire.
- Check for continuity between the B16 terminal (BRN) and ground. There should be continuity under all conditions. If the test result is different, check for a poor ground (G401) or an open in the wire.
- If the input test found nothing wrong, but the indicator is faulty, replace the printed circuit board.
