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. Remove the gauge assembly from the dashboard, then disconnect gauge assembly connectors A (30 P) and C (16P).
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).





5. Check for voltage between gauge assembly connector terminals and body ground in each shift lever position:
- Between A7 (BLK/BLU) and ground in the P position.
- Between A8 (WHT) and ground in the R position.
- Between A9 (RED/BLK) and ground in the N position.
- Between A27 (YEL) and ground in the D4 position
- Between A11 (PNK) and ground in the D3 position.
- Between A10 (BLU) and ground in the 2 position.
- Between A12 (BRN) and ground in the 1 position.
There should be 0 V at each terminal to ground in each position, and there should be about 5 V in any other position.
6. Shift the shift lever into the D5 position, and check for voltage between gauge assembly connector terminal A28 (BLK/RED) and body ground. There should be battery voltage in the D5 position, and there should be 0 V in any position other than the D5.
7. If the test result are different, check for an open in the wire(s), a faulty transmission range switch, or a faulty PCM.





8. Check for voltage between gauge assembly connector terminal C10 (YEL) and body ground with the ignition switch turned ON (II). There should be battery voltage. If there is no voltage, check for a blown No. 9 (10 A) fuse in the driver's under-dash fuse/relay box or an open in the wire.





9. Turn the ignition switch OFF, and check for continuity between connector terminal C12 (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 (G501).
10. Connect gauge assembly connectors A (30P) and C (16P).





11. Turn the ignition switch ON (II), and check for voltage in about 2 seconds between connector terminals A24 (RED/GRN) and body ground, and between A28 (BLK/RED) and ground. There should be battery voltage within about 2 seconds after the ignition switch is turned ON (II).
12. If all input tests prove OK, but the indicator is faulty, replace the gauge assembly.
