A/T Gear Position Indicator Input Test - Without 7-speed Mode

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 does not come on, and the A/T gear position indicator does not come on, 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 [P] position, and check for continuity between B14 terminal (BLU/BLK) and ground. There should be continuity in [P] position and no continuity in any other shift lever position. If the test results are different, check for faulty transmission range switch or open in the wire.

 

6.Turn the ignition switch ON (II), and shift to [R] position with pressing the brake pedal. Check for voltage between B13 terminal (WHT) and ground. There should be 0 V in [R] position, and about 10 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 [N] position, and check for continuity between B12 terminal (RED/BLK) and ground. There should be continuity in [N] position and no continuity in any other position. If the test results are different, check for faulty transmission range switch or open in the wire.

8.Shift to [D] position, and check for voltage between B9 terminal (PNK) and ground. There should be battery voltage in [D] position, and 0 V in any other position. If the test results are different, check for faulty transmission range switch and PCM, or an open in the wire.

9.Shift to [S] position, and check for voltage between B8 terminal (BLU/WHT) and ground. There should be 0 V in [S] position, and about 10 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.Shift to [L] position, and check for voltage between B10 terminal (BLU) and ground. There should be 0 V in [L] position, and about 10 V in any other position. If the test results are different, check for a faulty transmission range switch or an open in the wire.

11.Check for voltage between A2 terminal (YEL) and ground. There should be battery voltage. If the test result is different, check for a blown No. 16 (7.5A) fuse in the under-dash fuse/relay box or an open in the wire.

 

12.Check for continuity between A9 terminal (BLK) and ground. There should be continuity under all conditions. If the test result is different, check for a poor ground (G501) or an open in the wire.

13.If a input test prove OK, but the indicator is faulty, replace the gauge assembly.
