STEP 1. Check the brake pedal stroke sensor installation.
STEP 2. Damage check of the harness wires (PHEV-ECU connector and brake pedal stroke sensor connector).
STEP 3. Voltage measurement at brake pedal stroke sensor connector (CNTP terminal).
(1) Disconnect the brake pedal stroke sensor connector and measure the harness connector side.
(2) Turn on the power supply mode of the electric motor switch.
(3) Measure the voltage between the brake pedal stroke sensor connector (terminal 5V) and body ground.OK: Approximately 5 V
Is the check result normal?
Go to Step 4. Replace the PHEV-ECU (Refer to ). Then go to Step 6.
STEP 4. Using scan tool (M.U.T.-IIISE), check the data list. <PHEV-ECU>
STEP 5. Test the OBD-II drive cycle.
STEP 6. Test the OBD-II drive cycle.
(1) Carry out a test drive with the drive cycle pattern. Refer to Diagnostic Function - OBD-II Drive Cycle - Pattern 1 . (2) Check if the DTC is set.
Is the DTC set?
Retry the troubleshooting. The procedure is complete.
