A/T Gear Position Indicator Input Test - With 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, 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 B14 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 faulty transmission range switch or open in the wire.

 

6.Turn the ignition switch ON (II), and shift to the [R] position with pressing the brake pedal. Check for voltage between B13 terminal (WHT) and ground. There should be 0 V in the [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 the [N] position, and check for continuity between B12 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 faulty transmission range switch or open in the wire.

8.Shift to the [D] position, and check for voltage between B9 terminal (PNK) 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 PCM, or an open in the wire.

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

10.Shift to the [L] position, and check for voltage between B10 terminal (BLU) and ground. There should be 0 V in the [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.Shift to the [D] or [S] position, push the main switch (7SPEED MODE) (A), then push both plus (+) and minus (-) of the steering shift switches (B).

 

12.Check for voltage between B11 terminal (BRN/WHT) and ground. There should be battery voltage 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 for faulty main switch (7SPEED MODE)/steering shift switch and PCM, or an open in the wire.

 

13.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.

 

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

15.Turn the ignition switch OFF.

16.Connect gauge assembly connectors A (20P) and B (14P).

17.Start the engine, and shift to the [D] or [S] position.Push the main switch (7SPEED MODE), then push the steering shift switch plus(+). The shift indicator displays 1 in the shift indicator.

18.Check for LED A voltage between B5 terminal and ground,and check for LED B voltage between B4 and ground. There should be about 5 V.
Check for LED C voltage between B3 terminal and ground. There should be about 0.3 V.

 

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