P0713
DTC P0713: TC-SST-ECU temperature sensor system (Output high range out)
CAUTION:
- If there is any problem in the CAN bus lines, an incorrect diagnostic trouble code may be set. Prior to this diagnosis, diagnose the CAN bus lines.
- Whenever the ECU is replaced, ensure that the CAN bus lines are normal.
DIAGNOSTIC FUNCTION
TC-SST-ECU checks that the output of the ECU temperature sensor is normal.
DESCRIPTIONS OF MONITOR METHODS
The output of the ECU temperature is determined to be too high.
MONITOR EXECUTION

- MB991910 M.U.T.-III Main Harness A
STEP 1. Scan tool CAN bus diagnostics
Using scan tool MB991958, diagnose the CAN bus lines.
Q. Is the check result normal?
YES Go to Step 2.
NO Repair the CAN bus lines. CAN Bus Diagnostics Chart.) After repairing the CAN bus line, go to Step 2.
STEP 2. Check whether the DTC is reset.
30 seconds after turning ON the ignition switch, check that the DTC is reset.
Q. Is DTC No. P0713 set?
YES Replace the transaxle assembly. (Refer to Removal and Replacement.)
