7. Raise the front of the vehicle, and make sure it is

securely supported.

8. Set the parking brake, and block the rear wheels

securely.

9. Start the engine, then shift to D3 position and let

the wheels spin in 3rd gear for more than 5
seconds.

10. Measure the voltage between PCM connector

terminals D13 and B20 or B22 .

Check for loose terminal fit in the PCM

connectors. If necessary, substitute a known-good
PCM and recheck.

Go to step 11.

11. Turn the ignition switch OFF.

12. Disconnect the 3rd clutch transmission fluid

pressure switch connector.

13. Turn the ignition switch ON (II).

14. Measure the voltage between the 3rd clutch

transmission fluid pressure switch connector
terminal and body ground.

Go to step 15.

Repair open in the wire between the 3rd

transmission fluid clutch pressure switch and the
PCM.

15. Measure the resistance between the 3rd clutch

transmission fluid pressure switch connector
terminal and body ground.

Check for loose terminal fit in the PCM

connectors. If necessary, substitute a known-good
PCM and recheck.

Replace the 3rd clutch transmission fluid

pressure switch (see page 14-365).

NOTE:

• Record all freeze data and review General

Troubleshooting Information (see page 14-247)
before you troubleshoot.

• This code is caused by an electrical circuit problem

and cannot be caused by a mechanical problem in the
transmission.

1. Turn the ignition switch ON (II).

2. Shift to all positions other than R.

3. Measure the voltage between PCM connector

terminals D6 and B20 or B22 .

Go to step 4.

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 PCM connector
terminals B20 and B22 and body ground (G101). If
the wires are OK, check for loose terminal fit in the
PCM connectors. If necessary, substitute a known-
good PCM and recheck.

4. Shift to all positions other than P or N.

5. Measure the voltage between PCM connector

terminals B14 and B20 or B22 .

Go to step 6.

Check for a short in the wire between PCM

connector terminal B14 terminal and the
transmission range switch. If the wires are OK,
check for loose terminal fit in the PCM connectors.
If necessary, substitute a known-good PCM and
recheck.

Go to step 8.

Check for a short in the wire between PCM

connector terminal D9 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.

8. Shift to all positions other than D3.

9. Measure the voltage between PCM connector

switch or A/T gear position indicator. If the wires
are OK, check for loose terminal fit in the PCM
connectors. If necessary, substitute a known-good
PCM and recheck.
