Inspection Procedure 21: AS&G System Abnormal (auto start carried out under condition that clutch pedal not operated) <M/T>
 
 
 
 
FUNCTION
When the specified conditions are satisfied, the engine-ECU will restart the engine regardless of the driver's intention.
 
 
COMMENTS ON TROUBLE SYMPTOM
The failure could possibly be caused by the failed AS&G system. The engine-ECU, however, can possibly carry out the forced auto start, depending on the vehicle status or the ambient conditions.
 
 
PROBABLE CAUSES
  • Failed AS&G system
  • Failed engine-ECU
 
 
DIAGNOSIS PROCEDURE
STEP 1. Confirm the vehicle status and the ambient conditions.
  • Confirm the vehicle status or the ambient conditions to check whether the forced auto start should be carried out or not (For details, refer to the relevant Technical Information Manual - GROUP 13A - AS&G system).
Are the conditions for carrying out the forced auto start satisfied?
Check end.
Go to Step 2.
 
STEP 2. M.U.T.-IIISE diagnosis code
Is the diagnosis code set?
Inspection chart for diagnosis code (Refer to ).
Go to Step 3.
 
STEP 3. M.U.T.-IIISE other system diagnosis code
  • Confirm whether the diagnosis code is set in the A/C-ECU.
Is the diagnosis code set?
Perform the troubleshooting of the A/C-ECU (Refer to GROUP 55 - Troubleshooting - Diagnosis Code Chart ).
Go to Step 4.
 
STEP 4. M.U.T.-IIISE data list
  • Data list reference table (Refer to ).
    1. Item 186: Clutch monitoring switch (upper)
    2. Item 187: Clutch interlock switch (bottom)
Are the check results normal?
Go to Step 5.

STEP 5. M.U.T.-IIISE data list
  • Item 4: Vehicle speed
OK: 0 km/h (Vehicle: Stopped)
Is the check result normal?
Go to Step 6.
Perform the troubleshooting of the ASC-ECU (Refer to GROUP 35C - Troubleshooting - Diagnosis Code Chart ).
 
STEP 6. M.U.T.-IIISE data list
  • Item 6: Engine coolant temperature sensor
OK:
  • Engine cold state: At ambient temperature (atmospheric temperature) or equivalent.
  • Engine hot state: At 80 - 120°C
Is the check result normal?
Go to Step 7.
Perform the troubleshooting of the engine coolant temperature sensor. Inspection chart for diagnosis code (Refer to ).
 
STEP 7. Check the trouble symptom.
Does the trouble symptom persist?
Replace the engine-ECU.
Intermittent malfunction (Refer to GROUP 00 - How to Use Troubleshooting/Inspection Service Points - How to Cope with Intermittent Malfunctions ).
