A/T Gear Position Indicator Input Test

1.If the MIL has been reported, check for a DTC, and repair the system as indicated by DTC.

2.If the MIL does not come on, and the A/T gear position indicator [P], [N], or [R] does not come on, remove the gauge assembly from the dashboard, then disconnect gauge assembly connector A (22P) and B (22P).

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.Turn the ignition switch ON (II).

6.Shift to [P] position, and check for continuity between B2 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 a faulty transmission range switch or an open in the wire.

NOTE: The illustration shows example of connector terminal arrangement; connector terminal arrangement varies with models.

 

7.Shift to [R] position, and check for voltage between B4 terminal (WHT) and ground.
There should be 0 V in [R] position. There should be battery voltage in any other shift lever position. If the test results are different, check for a faulty transmission range switch or an open in the wire.

8.Shift to [N] position, and check for continuity between B3 terminal (BLK/RED) and ground.
There should be continuity in [N] position and no continuity in any other shift lever position. If the test results are different, check for faulty transmission range switch or an open in the wire.

9.Check for voltage A18 terminal (YEL) and ground with the ignition switch ON (II).
There should be battery voltage. If the test result is different, check for a blown No. 10 (7.5A) fuse in the under-dash fuse/relay box or an open in the wire.

NOTE: The illustration shows example of connector terminal arrangement; connector terminal arrangement varies with models.

 

10.Turn the ignition switch OFF, and check for continuity between A3 terminal (BLK) and ground under all conditions.
There should be continuity. If the test result is different, check for a poor ground (G502) or an open in the wire.

11.If a input test prove OK, but the indicator is faulty, replace the printed circuit board.
