STEP 1. Voltage measurement at transmission range switch connector (terminal No. 3)
(1) Disconnect the transmission range switch connector, and measure at the wiring harness side.
(2) Turn the ignition switch to the "ON" position.
(3) Measure the voltage between the transmission range switch connector (terminal No. 3) and body ground.OK: 10 V or more
Is the check result normal?
Go to Step 2. Repair the connector(s) or the wiring harness (power supply line between the transmission range switch connector terminal No. 3 and the ETACS-ECU connector).
STEP 2. Check for open circuit or short to ground in INHP, INHR, INHN, INHD and INHL line between the transmission range switch connector and the TCM connector
STEP 3. Transmission range switch and control cable adjustment
STEP 4. Transmission range switch continuity check
STEP 5. Voltage measurement at TCM connector (INHP, INHR, INHN, INHD and INHL terminal)
(1) Connect the transmission range switch connector.
(2) Disconnect the TCM connector, and measure at the wiring harness side.
(3) Turn the ignition switch to the "ON" position.
(4) Measure the voltage at each terminal when the selector lever is moved to each range.- At P range: Between the TCM connector (INHP terminal) and body ground
- At R range: Between the TCM connector (INHR terminal) and body ground
- At N range: Between the TCM connector (INHN terminal) and body ground
- At D range: Between the TCM connector (INHD terminal) and body ground
- At L range: Between the TCM connector (INHL terminal) and body ground
OK: 10 V or more
Is the check result normal?
Go to Step 6. Repair the connector(s) or the wiring harness.
STEP 6. Symptom recheck after erasing diagnostic trouble code
