DIAGNOSIS CODE SET CONDITION
Check Conditions
  • More than 2 seconds have passed since the ignition switch was turned to "ON" position.
  • ACC/FCM-ECU power voltage is more than 9 V and is less than 18 V.
Judgement Criterion
  • A signal, which indicates a defective ASC system, is received from the ASC-ECU.
 
 
PROBABLE CAUSES
  • Malfunction of the ASC system
  • Malfunction of ACC/FCM-ECU

 
 
DIAGNOSIS PROCEDURE
STEP 1. M.U.T.-IIISE diagnosis code.
Is any other the diagnosis code than C1753 set?
Inspection Chart for Diagnosis Code (Refer to ).
Go to Step 2.
 
STEP 2. Check the ASC system diagnosis code.
Using M.U.T.-IIISE, perform ASC system diagnosis code (Refer to GROUP 35C - Troubleshooting, Diagnosis Function ).
Is the diagnosis code set?
Repair the ASC system (Refer to GROUP 35C - Troubleshooting, Inspection Chart for Diagnosis Code ).
Go to Step 3.
 
STEP 3. Check whether the diagnosis code is set again.
Is diagnosis code No.C1777 set?
Replace the ACC/FCM-ECU (Refer to ).
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 ).
