KU, KU-H, KN, KM, KT, KP, KW, FO, MA, PH, IN, and KZ Models


NOTE: Record all freeze data before you troubleshoot.

1.Turn the ignition switch ON (II).

2.Observe the A/T gear position indicator while shifting to each position.

Do any indicators stay on when the shift lever is not in that position?


YES - Go to 3.


NO - Turn the ignition switch OFF, then go to 4.


3.Disconnect the transmission range switch connector, and watch the A/T gear position indicator.

Do all gear position indicators go out?


YES - Replace the transmission range switch.n


NO - Turn the ignition switch OFF, then go to 5.


4.Inspect the transmission range switch.

Is the switch OK?


YES - Go to 5.


NO - Replace the transmission range switch.n


5.Connect the transmission range switch connector.

6.Turn the ignition switch ON (II).

7.Shift to all positions other than P.

8.Measure the voltage between PCM connector terminals D6 and A23 or A24.

 

Is there about 5 V?


YES - Go to 9.


NO - Check for a short in the wire between PCM connector terminal D6 and the  transmission range switch or A/T gear position indicator, and check for an open in the wires between ground  G101 and PCM connector terminals A23 and A24. If the wires are OK, check for loose terminal fit in the PCM connectors. If necessary, substitute a known-good  PCM and recheck.n

9.Shift to all positions other than R.

10.Measure the voltage between PCM connector terminals D5 and A23 or A24.

 

Is there about 5 V?


YES - Go to 11.


NO - Check for a short in the wire between PCM connector terminal D5 and the  transmission range switch or A/T gear position indicator. If the wire is OK, check for loose terminal fit in the PCM connectors. If necessary, substitute a known-good  PCM and recheck.n

11.Measure the voltage between PCM connector terminals C12 and A23 or A24.

 

Is there about 5 V?


YES - Go to 12.


NO - Check for a short in the wire between PCM connector terminal C12 and the  transmission range switch. If the wire is OK, check for loose terminal fit in the PCM connectors. If necessary, substitute a known-good  PCM and recheck.n

12.Shift to all positions other than N.

13.Measure the voltage between PCM connector terminals D4 and A23 or A24.

 

Is there about 5 V?


YES - Go to 14.


NO - Check for a short in the wire between PCM connector terminal D4 and the  transmission range switch or A/T gear position indicator. If the wire is OK, check for loose terminal fit in the PCM connectors. If necessary, substitute a known-good  PCM and recheck.n

14.Shift to all positions other than D.

15.Measure the voltage between PCM connector terminals D10 and A23 or A24.

 

Is there about 5 V?


YES - Go to 16.


NO - Check for a short in the wire between PCM connector terminal D10 and the  transmission range switch. If the wire is OK, check for loose terminal fit in the PCM connectors. If necessary, substitute a known-good  PCM and recheck.n

16.Shift to all positions other than 2.

17.Measure the voltage between PCM connector terminals C11 and A23 or A24.

 

Is there about 5 V?


YES - Go to 18.


NO - Check for a short in the wire between PCM connector terminal C11 and the  transmission range switch. If the wire is OK, check for loose terminal fit in the PCM connectors. If necessary, substitute a known-good  PCM and recheck.n

18.Shift to all positions other than 1.

19.Measure the voltage between PCM connector terminals C19 and A23 or A24.

 

Is there about 5 V?


YES - Check for loose terminal fit in the PCM connectors. If necessary, substitute a known-good  PCM and recheck.n


NO - Check for a short in the wire between PCM connector terminal C19 and the transmission range switch. If the wire is OK, check for loose terminal fit in the PCM connectors. If necessary, substitute a known-good  PCM and recheck.n
