Inspection Procedure 22: AS&G System Abnormal (auto start carried out under condition that brake pedal operated) <CVT>
 
 
 
 
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 DI and MPI system
  • Failed CVT system
  • Failed ASC 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
Confirm whether the diagnosis code is set in the ECUs below.
  • Engine-ECU
  • CVT-ECU
  • ASC-ECU
  • A/C-ECU
Is the diagnosis code set?
YES <Diagnosis code is set in the engine-ECU> : Inspection chart for diagnosis code (Refer to ).
YES <Diagnosis code is set in the CVT-ECU> : Perform the troubleshooting of the CVT-ECU (Refer to GROUP 23A - Troubleshooting - Diagnosis Code Chart ).
YES <Diagnosis code is set in the ASC-ECU> : Perform the troubleshooting of the ASC-ECU (Refer to GROUP 35C - Troubleshooting - Diagnosis Code Chart ).
YES <Diagnosis code is set in the A/C-ECU> : Perform the troubleshooting of the A/C-ECU (Refer to GROUP 55 - Troubleshooting - Diagnosis Code Chart ).
Go to Step 3.
 
STEP 3. M.U.T.-IIISE data list

    1. Item DD: Relative accelerator pedal position sensor
Is the check result normal?
Go to Step 8.
Perform the troubleshooting of the accelerator pedal position sensor. Inspection chart for diagnosis code (Refer to ).
 
STEP 8. M.U.T.-IIISE data list
  • Data list reference table (Refer to ).
    1. Item 171: Brake booster pressure sensor
Is the check result normal?
Go to Step 9.
Perform the troubleshooting of the brake booster pressure sensor. Inspection chart for diagnosis code (Refer to ).
 
STEP 9. Check the trouble symptom.
Does the trouble symptom persist?
Replace the engine-ECU.
