Problem in Lock-up Control

Solenoid Valve Circuit

NOTE: Record all freeze data and review General
Troubleshooting Information (see page 14-3) before
you troubleshoot.

1. Turn the ignition switch OFF.

2. Disconnect the B (25P) and D (16P) connectors from

the PCM.

3. Turn the ignition switch ON (II).

4. Measure the voltage between the D1 and B20 or

B22 terminals.

Repair short to power in the wire between

the D1 terminal and the lock-up control solenoid
valve.

Go to step 5.

5. Turn the ignition switch OFF.

6. Measure the resistance between the D1 and B20 or

B22 terminals.

Go to step 11.

Go to step 7.

7. Check for continuity between the B20 and B22

terminals and body ground.

Go to step 8.

Repair open in the wires between the B20 and

B22 terminals and ground (G101), or repair poor
ground (G101).

8. Disconnect the 3P connector from the lock-up

control solenoid valve/shift control solenoid valve
A assembly.

9. Check for continuity between the D1 and B20 or

B22 terminals.

Repair short to ground in the wire between

the D1 terminal and the lock-up control solenoid
valve.

Go to step 10.

10. Measure the resistance between the No. 3 terminal

of the lock-up control solenoid valve/shift control
solenoid valve A assembly connector and body
ground.

Check for an open in the wire between the D1

terminal and the lock-up control solenoid valve.

Replace the lock-up control solenoid valve/

shift control solenoid valve A assembly (see page
14-130).

11. Turn the ignition switch ON (II).

12. Measure the voltage between the D5 and B20 or

B22 terminals.

Check for loose terminal fit in the PCM

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

Check for blown No. 6 (15A) fuse in the

driver’s under-dash fuse/relay box. If the fuse is OK,
repair open in the wire between the D5 terminal
and the driver’s under-dash fuse/relay box.

Problem in A/T Clutch Pressure

Control Solenoid Valve A 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. Disconnect the 2P connector from A/T clutch

pressure control solenoid valve A.

2. Measure A/T clutch pressure control solenoid

resistance at the solenoid valve connector.

Go to step 3.

Replace the A/T clutch pressure control

solenoid valve A/B assembly (see page 14-133).

3. Disconnect the B (25P) connector from the PCM.

4. Check for continuity between body ground and the

B8 terminal and the B17 terminal individually.

Repair short to ground in the wires between

the B8 and B17 terminals and A/T clutch pressure
control solenoid valve A.

Go to step 5.

5. Connect the A/T clutch pressure control solenoid

valve A connector.

6. Measure the resistance between the B8 and B17

terminals.

Go to step 7.

Repair loose terminal or open in the wires

between the B8 and B17 terminals and A/T clutch
pressure control solenoid valve A.
