| 1. | If the D indicator or MIL has been reported on, check for a DTC, and repair the system as indicated by DTC. |
| 2. | If the D indicator, A/T gear position indicator, and M indicator do not come on, or the shift indicator works improperly, remove the gauge assembly from the dashboard, then disconnect the gauge assembly connectors A (20P) and B (14P). |
| 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 gauge assembly connector terminal B14 and ground. There should be continuity in the P position and no continuity in any other shift lever position.
|
| 6. | Turn the ignition switch ON (II), and shift to the R position with pressing the brake pedal. Check for voltage between connector terminal B13 and ground. There should be 0 V in the R position, and about 5 V in any other position. |
| 7. | Shift to the N position, and check for continuity between connector terminal B12 and ground. There should be continuity in the N position, and no continuity in any other position. |
| 8. | Shift to the D position, and check for voltage between connector terminal B9 and ground. There should be about 5 V in the D position, and 0 V in any other position. |
| 9. | Shift to the S position, and check for voltage between connector terminal B8 and ground. There should be 0 V in the S position, and about 5 V in any other position. |
| 10. | Shift to the L position, and check for voltage between connector terminal B10 and ground. There should be 0 V in the L position, and about 5 V in any other position. |
| 11. | If the test results are different, check the transmission range switch and check for an open in the wires. |
| 12. | Shift to the D or S position, push the 7SPEED MODE main switch (A), and push steering shift + (plus) switch (B) or steering shift - (minus) switch (C).
|
| 13. | Check for voltage between connector terminal B11 and ground. There should be about 5 V in the 7-speed manual shifting mode, and 0 V out of the 7-speed manual shifting mode. If the test results are different, check 7SPEED MODE main switch circuit and steering shift switch circuit.
|
| 14. | Check for voltage between connector terminal A2 and ground. There should be battery voltage with the ignition switch turned ON (II). If the voltage is 0 V, check for a blown No. 16 (7.5A) fuse in the under-dash fuse/relay box or an open in the wire.
|
| 15. | Check for continuity between connector terminal A9 and ground. There should be continuity under all conditions. If there is no continuity, check for a poor ground (G501) or an open in the wire. |
| 16. | Turn the ignition switch OFF. |
| 17. | Connect gauge assembly connectors A (20P) and B (14P). |
| 18. | Check for LED A voltage between connector terminal B5 terminal and ground, and check for LED B voltage between terminal B4 and ground. There should be about 5 V.
|
| 19. | Check for LED C voltage between terminal B3 and ground. There should be about 0.3 V. |
| 20. | If a input test prove OK, but the indicator is faulty, replace the gauge assembly. |
