1) Turn OFF the ignition switch.

2) Disconnect the TCM harness connector (E5).

3) Connect a test lamp between the clutch control solenoid (SL2) low-side control circuit (pin 16 of E42) of the transmission internal harness and the battery power supply. Does the test lamp illuminate?

Refer to "LHD Automatic Transmission" in the ETM (wiring diagram). (Open using the ETM viewer.).

Refer to "RHD Automatic Transmission" in the ETM (wiring diagram). (Open using the ETM viewer.).

Yes

=>Go to Inspection for short to ground in clutch control solenoid (SL2) low-side control circuit.

No

=>Go to Inspection of transmission internal harness.

6. Inspection for short circuit in clutch control solenoid (SL2) high-side control circuit

1) Inspect the clutch control solenoid (SL2) high-side control circuit between the TCM (pin 3 of E5) and the transmission internal harness (pin 15 of E42) for a short to the clutch control solenoid (SL2) low-side control circuit. Is the result normal?

Refer to "LHD Automatic Transmission" in the ETM (wiring diagram). (Open using the ETM viewer.).

Refer to "RHD Automatic Transmission" in the ETM (wiring diagram). (Open using the ETM viewer.).

Yes

=>Go to TCM replacement.

No
