STEP 1. Voltage measurement at TCM connector (PRPS terminal)
(1) Drive the vehicle until the engine is warmed up.
(2) Measure the TCM connector side by backprobing.
(3) Selector lever position: N range.
(4) Engine: Idling
(5) Measure the voltage between the TCM connector (PRPS terminal) and body ground.
Is the voltage approximately 0.09 V or less?
Go to Step 2. Go to Step 8.
STEP 2. Voltage measurement at CVT assembly connector (SSPW terminal)
(1) Disconnect the CVT assembly connector connector, and measure at the wiring harness side.
(2) Turn the ignition switch to the "ON" position.
(3) Measure the voltage between the CVT assembly connector (SSPW terminal) and body ground.OK: approx. 5 V
Is the check result normal?
Go to Step 4. : Go to Step 3.
STEP 3. Check for open circuit or short to ground in SSPW line between the CVT assembly connector and the CVT-ECU connector
STEP 4. Check for open circuit or short to ground in PRPS line between the CVT assembly connector and the TCM connector
STEP 5. Check for open circuit in SGND line between the CVT assembly connector and the TCM connector
STEP 6. Check for open circuit or short to ground in signal line between the CVT assembly connector and the valve body harness connector (primary pressure sensor line)
STEP 7. Check for open circuit or short to ground in power supply line between the CVT assembly connector and the valve body harness connector (sensor power supply line)
STEP 8. Voltage measurement at TCM connector (PRPS terminal)
(1) Drive the vehicle until the engine is warmed up.
(2) Measure the TCM connector side by backprobing.
(3) Selector lever position: N range.
(4) Engine: Idling
(5) Measure the voltage between the TCM connector (PRPS terminal) and body ground.OK: approx. 0.90 - 0.92 V
Is the check result normal?
Go to Step 9. Replace the valve body assembly. (Refer to )
STEP 9. Symptom recheck after erasing diagnostic trouble code
