Code No. C1394 INCOMP.learn neutral(SAS)
 
 
caution
  • Whenever the ECU is replaced, ensure that the CAN bus lines are normal.
  • When the steering wheel sensor is replaced, calibrate the steering wheel sensor (Refer to GROUP 35C - On-vehicle Service ).
 
 
OPERATION
FCM/LDW/AHB-ECU communicates with the steering wheel sensor via the CAN bus lines.
 
 
DIAGNOSIS CODE SET CONDITION
This diagnosis code is set when the abnormality below is detected:
  • The steering wheel sensor has not learned the neutral position yet.
 
 
PROBABLE CAUSES
  • Neutral position of steering wheel sensor not learned
  • Malfunction of the steering wheel sensor (column switch assembly)
  • Malfunction of the FCM/LDW/AHB-ECU
 
 
DIAGNOSIS PROCEDURE
STEP 1. Steering wheel sensor calibration.
Perform calibration of steering wheel sensor (Refer to GROUP 35C - On-vehicle Service ).
Has the calibration succeeded?
Go to Step 2.
Replace the steering wheel sensor (column switch assembly) (Refer to ).
 
STEP 2. Check whether the diagnosis code is set again.
Check again if the diagnosis code is set in the FCM/LDW/AHB-ECU.
(1) Erase the diagnosis code.
(2) Turn the ignition switch from "LOCK" (OFF) position to "ON" position.
(3) Check if diagnosis code is set.
Is the diagnosis code set?
Replace the FCM/LDW/AHB-ECU (Refer to ).
This diagnosis is complete.
