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. Test the transmission range switch (see page 14-
403).
Go to step 2.
Replace the transmission range switch (see
page 14-404).
2. Turn the ignition switch OFF.
3. Check for continuity between PCM connector
terminals B20 and body ground, and between B22
and body ground.
Go to step 4.
Repair open in the wire between PCM
connector terminals B20, B22, and ground (G101),
or repair poor ground (G101).
4. Turn the ignition switch ON (II).
5. Shift to the D position.
6. Measure the voltage between PCM connector
terminals D9 and B20 or B22 .
Repair open in the wire between PCM
connector terminal D9 and the transmission range
switch.
Go to step 7.
7. Shift to the R position.
8. Measure the voltage between PCM connector
terminals D6 and B20 or B22 .
Repair open in the wire between PCM
connector terminal D6 and the transmission range
switch.
Go to step 9.

9. Shift to the P and N position.
10. Measure the voltage between PCM connector
terminals B14 and B20 or B22.
Repair open in the wire between PCM
connector terminal B14 and the transmission range
switch.
Go to step 11.
11. Shift to the D3 position.
12. Measure the voltage between PCM connector
terminals D8 and B20 or B22.
Repair open in the wire between PCM
connector terminal D8 and the transmission range
switch.
Go to step 13.
13. Shift to the 2 position.
14. Measure the voltage between PCM connector
terminals D14 and B20 or B22.
Repair open in the wire between PCM
connector terminal D14 and the transmission range
switch.
Go to step 15.
15. Shift to the 1 position.
16. Measure the voltage between PCM connector
terminals D15 and B20 or B22.
Repair open in the wire between PCM
connector terminal D15 and the transmission range
switch.
Check for loose terminal fit in the PCM
connectors. If necessary, substitute a known-good
PCM and recheck.

NOTE: Record all freeze data and review General
Troubleshooting Information (see page 14-247) before
you troubleshoot.
1. Turn the ignition switch ON (II).
2. Measure the voltage between PCM connector
terminals B19 and B20 or B22.
Go to step 7.
Go to step 3.
3. Turn the ignition switch OFF.
4. Disconnect PCM connector B (25P).
5. Disconnect the 4th clutch transmission fluid
pressure switch connector.
6. Check for continuity between PCM connector
terminal B19 and body ground.
Repair short to ground in the wire between
PCM connector terminal B19 and the 4th clutch
transmission fluid pressure switch.
Disconnect the 4th clutch transmission fluid
pressure switch connector, and go to step 15.
