1. If the MIL has been reported on, check for a DTC,

and repair the system as indicated by DTC.

2. If the MIL does not come on, and A/T gear position

indicator P, R, or N does not come on, remove the
gauge assembly from the dashboard, then
disconnect the gauge assembly connector A (22P)
and B (18P).

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 the P position, and check the voltage

between gauge assembly terminal A20 (BLU/BLK)
and ground. There should be 0 V in the P position
and about 5 V in any other shift lever position. If the
test results are different, check for faulty
transmission range switch or an open in the wire.

7. Shift to the R position, and check the voltage

between gauge assembly terminal A19 (WHT) and
ground. There should be 0 V in the R position and
about 5 V in any other shift lever position. If the test
results are different, check for faulty transmission
range switch or an open in the wire.

8. Shift to the N position, and check the voltage

between gauge assembly terminal A17 (BLK/RED)
and ground. There should be 0 V in the N position
and 5 V 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 the voltage between gauge assembly

terminal B7 (YEL) and ground. There should be
battery voltage. If the test result is different, check
for a blown No. 10 (7.5 A) fuse in the under-dash
fuse/relay box or an open in the wire.

10. Turn the ignition switch OFF, and check for

continuity between gauge assembly terminal B17
terminal and ground. There should be continuity
under all conditions. If the test result is different,
check for a poor ground (G401) or open in the wire.

11. If all input tests prove OK, but the indicator is faulty,

replace the printed circuit board.
