Indicator Input Test

Indicator Input Test
1. If the [D] indicator light or MIL has been reported on, check for a DTC, and repair the system as indicated by the DTC.
2. If the [D] indicator light 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).
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. 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.
6. 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.
7. 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.
8. 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 0 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.
9. 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.





10. Turn the S mode switch on with the shift lever in the [D] position. Check for voltage between B1 terminal (LT GRN) and ground. There should be battery voltage and 0 V with the S mode switch turned off. If the test results are different, check for a faulty mode switch and TCM, or an open in the wire.
11. Check for voltage between the Be 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.
12. 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.
13. If the input test found nothing wrong, but the indicator is faulty, replace the printed circuit board.
