17 -ENGINE AND EMISSION CONTROL > ADAPTIVE CRUISE CONTROL SYSTEM (ACC) > DIAGNOSIS CODE PROCEDURES > CODE NO. C2350: RECEIVED FCM TEMPORARY FAIL FROM FCM/LDW/AHB ECU
Code No. C2350: Received FCM temporary fail from FCM/LDW/AHB ECU
 
 
caution
  • Whenever the ECU is replaced, ensure that the CAN bus lines are normal.
  • When the ACC/FCM-ECU is replaced, calibrate the radar (refer to ).
 
 
OPERATION
ACC/FCM-ECU communicates with the FCM/LDW/AHB-ECU via the CAN bus lines.
 
 
DIAGNOSIS CODE SET CONDITION
Check Conditions
  • More than 5 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 temporary failure the FCM system, is received from the FCM/LDW/AHB-ECU.
noteA diagnosis code is not set as a historic fault.
 
 
PROBABLE CAUSES
  • Defective of the FCM/LDW/AHB system (FCM control related)
  • Temporary failure of the ACC/FCM-ECU
 
 
DIAGNOSIS PROCEDURE
STEP 1. M.U.T.-IIISE other system diagnosis code.
Use M.U.T.-IIISE to check that any diagnosis code is set in FCM/LDW/AHB-ECU (Refer to GROUP 54A - FCM/LDW/AHB-ECU ).
Is the diagnosis code set?
Perform the relevant troubleshooting (Refer to GROUP 54A - FCM/LDW/AHB-ECU ).
Go to Step 2.
 
STEP 2. Check whether the diagnosis code is set again.
Is the diagnosis code No.C2350 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 ).
