17 -ENGINE AND EMISSION CONTROL > ADAPTIVE CRUISE CONTROL SYSTEM (ACC) > SYMPTOM PROCEDURES > CRUISE CONTROL CANNOT BE SET.
Inspection Procedure 3: Adaptive Cruise Control cannot be Set (No Response SET - Switch and RES + Switch is Pressed).
 
 
cautionWhen the ACC/FCM-ECU is replaced, calibrate the radar (refer to ).
 
 
COMMENTS ON TROUBLE SYMPTOM
  • The conditions for initiating the adaptive cruise control (ACC) system may not be satisfied.
  • The fail-safe function is probably cancelling ACC system. In this case, checking the DI and MPI system, ASC system and electric parking brake system diagnosis codes.
 
 
PROBABLE CAUSES
  • Malfunction of the cruise control switch (integrated with SET -, RES + switch)
  • Malfunction of the engine-ECU
  • Malfunction of the ACC/FCM-ECU
  • Malfunction of the DI and MPI system
  • Malfunction of the ASC system
  • Malfunction of the electric parking brake system
 
 
DIAGNOSIS PROCEDURE
STEP 1. Check the DI and MPI system data list.
Using M.U.T.-IIISE, check the DI and MPI system data list (Refer to GROUP 13A - Troubleshooting, Data List Reference Table ).
  • Item No.91: RES + switch
  • Item No.92: SET - switch
Is the check result normal?
Go to Step 3.
Go to Step 2.
 
STEP 2. Check the cruise control switch (integrated with SET -, RES + switch).
Refer to .
Is the check result normal?
Replace the engine-ECU (Refer to GROUP 13A - Engine-ECU ).
Replace the cruise control switch (integrated with SET -, RES + switch) (Refer to ).
 
STEP 3. M.U.T.-IIISE data list.
Check the following data list (Refer to ).
  • Item No.22: ACC switch state
Is the check result normal?
Go to Step 4.
Replace the ACC/FCM-ECU (Refer to ).
 
STEP 4. Check the symptom.
When the ACC start conditions are satisfied, confirm whether a trouble symptom reappears or not (For details, refer to the relevant Technical Information Manual - GROUP 17 - Adaptive Cruise Control System).
Can adaptive cruise control be set?
It can be assumed that this malfunction is intermittent (Refer to GROUP 00 - How to Use Troubleshooting/Inspection Service Points, How to Cope with Intermittent Malfunction ).
Replace the ACC/FCM-ECU (Refer to ).
