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 either A/T gear position indicator does not come on, remove the gauge assembly from the dashboard, then disconnect gauge assembly connectors 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.For KX model: If no indicator is lit, remove that indicator bulb from the gauge assembly, and check for a burned-out. If the bulb has burned out, replace the indicator bulb.

6.Turn the ignition switch ON (II).

7.Shift to the P position, and check for voltage between gauge assembly connector terminal B7 and ground.
There should be 0 V in the P 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.

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

 

8.Shift to the R position, and check for voltage between gauge assembly connector terminal B6 and ground.
There should be 0 V in the 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.

9.Shift to the N position, and check for voltage between gauge assembly connector terminal B17 and ground.
There should be 0 V in the N 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.

10.Check for voltage between gauge assembly connector terminal A15 and ground with the ignition switch ON (II).
There should be battery voltage. If there is no voltage, check for a blown No. 10 (7.5A) fuse in the under-dash fuse/relay box or open in the wire.

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

 

11.Turn the ignition switch OFF, and check for continuity between connector terminal A11 and ground under all conditions.
There should be continuity. If there is no continuity, check for a poor ground (G502) or open in the wire.

12.If a input tests prove OK, but the indicator is faulty, replace the printed circuit board or gauge assembly.
