STEP | CHECK | YES | NO |
1.CHECK HARNESS.
1) Turn the ignition switch to OFF.
2) Disconnect the TCM connector.
3) Disconnect the transmission connector.
4) Measure the resistance between TCM connector and chassis ground.
Connector & terminal
(B54) No. 15 — Chassis ground:
Is the resistance 1 M? or more?

Repair the short circuit of harness.
2.CHECK LOCK-UP DUTY SOLENOID.
Measure the resistance between transmission connector and transmission body.
Connector & terminal
(T4) No. 11 — Transmission body:
Is the resistance approx. 10 — 13.5 ?? (when cold)
Check for poor contact of connector, and if no fault is found, replace the TCM. Transmission Control Module (TCM)">

3.CHECK HARNESS INSIDE TRANSMISSION.
CAUTION:
Start work after ATF cools down.
1) Remove the transmission valve cover.
2) Check for the harness pinch, damage.
Is there any fault in the harness?
Replace the transmission harness.

4.CHECK HARNESS INSIDE TRANSMISSION.
1) Disconnect the control valve body connector.
2) Measure the resistance between transmission connector and transmission body.
Connector & terminal
(T4) No. 11 — Transmission body:
Is the resistance 1 M? or more?
Replace the control valve body. Control Valve Body">
Replace the transmission harness.
1. OUTLINE OF DIAGNOSIS
• Detect the ground short of the lock-up clutch pressure control solenoid drive circuit.
• Judge as NG when an abnormal signal is received from the solenoid driver IC of the lock-up clutch pressure control solenoid drive circuit.
2. EXECUTION CONDITION
Secondary Parameters | Execution condition |
12 V battery system voltage | ≥ 9 V |
Commanded duty of torque converter clutch pressure control solenoid | 100% |
3. DIAGNOSTIC METHOD
If the duration of time while the following conditions are met is longer than the time indicated, judge as NG.
Malfunction Criteria | Threshold Value |
Signal of malfunction from solenoid driver IC | ON |
As defined by: | |
Measured torque converter clutch pressure control solenoid voltage ≤ 0.8 V |
Time Needed for Diagnosis: 0.2 seconds
Malfunction Indicator Light Illumination: Illuminates as soon as a malfunction occurs.
