Indicator Input Test

Indicator Input Test
SRS components are located in this area. Review the SRS components locations, precautions, and procedures in the SRS section before performing repairs or service.
1. Remove the gauge assembly from the dashboard, then disconnect gauge assembly connectors A (30P) and C (14P).
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. Turn the ignition switch ON (II), and check for voltage in about 2 seconds between terminal C13 (GRN/BLK) and body ground, and between C11 (RED/GRN) and body ground. There should be battery voltage within about 2 seconds aster the ignition switch is turned ON (II).





5. Shift to the [P] position, and check for voltage between gauge assembly connector terminal C1 (BLU/BLK) and body ground. There should be 0 V in the [P] position. There should be battery voltage in any other shift lever position.
6. Shift to the [R] position, and check her voltage between terminal C2 (WHT) and body ground. There should be 0 V in the [R] position. There should be battery voltage in any other shift: lever position.
7. Shift to the [N] position, and check for continuity between terminal C3 (RED/BLK) and body ground. There should be continuity in the [N] position, and no continuity in any other shift lever position.





8. Shift to the [D] position, and check for voltage between terminal A13 (YEL) and body ground. There should be 0 V in the [D] position. There should be battery voltage in any other shift lever position.





9. Shift to the [D3] position, and check for voltage between terminal C4 (RED) and body ground. There should be 0 V in the [D3] position. There should be battery voltage in any other shift lever position.
10. Shift to the [2] position, and check for voltage between terminal C5 (BLU) and body ground. There should be 0 V in the [2] position. There should be battery voltage in any other shift lever position.
11. Shift to the [1] position, and check for voltage between terminal C6 (BRN) and body ground. There should be 0 V in the [1] position. There should be battery voltage in any other shift lever position.
12. If the test results are different, check for an open in the wire(s), a faulty transmission range switch, or a faulty PCM.





13. Check for voltage between terminal C8 (YEL) and body ground with the ignition switch ON (II). There should be battery voltage. If there is 0 V, check for a blown No. 9 (10A) fuse in the fuse in the driver's under-dash fuse/relay box or an open in the wire.





14. Turn the ignition switch OFF, and check for continuity between terminal C9 (BLK) and body ground.
There should be continuity to ground under all conditions.
If there is no continuity, check for an open in the wire, or poor ground (G502).
15. If all input tests prove OK, but the indicator is faulty, replace the printed circuit board.
