14. Shift to any position other than 2.
15. Measure the voltage between PCM connector
terminals C12 and A25 or A26.
Go to step 16.
Check for a short in the wire between PCM
connector terminal C12 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.
16. Shift to any position other than 1.
17. Measure the voltage between PCM connector
terminals C20 and A25 or A26.
Check for loose terminal fit in the PCM
connectors. If necessary, substitute a known-good
PCM and recheck.
Check for a short in the wire between PCM
connector terminal C20 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.

Switch Circuit
NOTE:
• Record all freeze data and review General
Troubleshooting Information (see page 14-3) before
you troubleshoot.
• This code is caused by an electrical circuit problem
and cannot be caused by a mechanical problem in the
transmission.
1. Test the transmission range switch (see page 14-
173).
Go to step 2.
Replace the transmission range switch (see
page 14-174).
2. Turn the ignition switch OFF.
3. Check for continuity between PCM connector
terminal A25 and body ground, and between
terminal A26 and body ground.
Go to step 4.
Repair open in the wires between PCM
connector terminals A25 and A26, and ground
(G101), or repair poor ground (G101).
4. Turn the ignition switch ON (II).
5. Shift to D4 position.
6. Measure the voltage between PCM connector
terminals C13 and A25 or A26.
Repair open in the wire between PCM
connector terminal C13 and the transmission range
switch.
Go to step 7.
7. Shift to R position.
8. Measure the voltage between PCM connector
terminals C21 and A25 or A26.
Repair open in the wire between PCM
connector terminal C21 and the transmission range
switch.
Go to step 9.
