Code No. C2262:
SAS offset threshold exceed
| caution |
- If there is any problem in the
CAN bus lines, an incorrect diagnosis code may be set. Prior to this diagnosis, diagnose the
CAN bus lines.
- Whenever the ECU is replaced, ensure that the CAN bus lines are normal.
- When the column switch assembly (Integrated with steering wheel sensor) is replaced,
calibrate the steering wheel sensor (Refer to On-vehicle Service
 ).
- When the FCM-ECU is replaced, calibrate the radar (refer to ).
|
OPERATION
FCM-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 output value deviates from the actual value.
| note |
A diagnosis code is not set as a historic fault.
|
PROBABLE CAUSES
- The CAN bus line is defective.
- Malfunction of the column switch assembly (Integrated with steering wheel sensor)
- Malfunction of the FCM-ECU
|
|
STEP 1. M.U.T.-III CAN bus diagnostics.
|
|
|
Use M.U.T.-III to diagnose the CAN bus lines.
|
|
|
Q.
Is the check result normal?
|
|
|
 Go to Step 2.
|
|
|
|
|
|
 Repair the CAN bus lines (Refer to GROUP 54C - Troubleshooting ).
|
|
|
|
|
|
STEP 2. Use M.U.T.-III to confirm a diagnosis code of other systems.
|
|
|
Check if the diagnosis code is set in the steering wheel sensor (Refer to Diagnosis Code
Chart ).
|
|
|
Q.
Is the diagnosis code set?
|
|
|
Troubleshoot the steering wheel sensor diagnosis code (Refer to Diagnosis Code
Chart ).
|
|
|
|
|
|
Go to Step 3.
|
|
|
|
|
|
STEP 3. Steering wheel sensor installation state check
|
|
|
Check that the column switch assembly (Integrated with steering wheel sensor) is installed
correctly (Refer to GROUP 54A - Column Switch .).
|
|
|
Q.
Is the check result normal?
|
|
|
Go to Step 4.
|
|
|
|
|
|
Install the column switch assembly (Integrated with steering wheel sensor) correctly
(Refer to GROUP 54A - Column Switch ).
|
|
|
|
|
|
STEP 4. M.U.T.-III data list of other systems.
|
|
|
Check the ASTC-ECU data list (Refer to ).
|
|
|
With the front wheel facing in the straight-ahead direction, check the steering wheel
sensor signal using the data list. Check that the data list deviates within ±5° from
the neutral position.
|
|
|
- Item No.7: Steering angle
|
|
|
Q.
Is the check result normal?
|
|
|
Go to Step 5.
|
|
|
|
|
|
Replace the column switch assembly (Integrated with steering wheel sensor) correctly
(Refer to GROUP 54A - Column Switch ).
|
|
|
|
|
|
STEP 5. Check whether the diagnosis code is set again.
|
|
|
Check again if the diagnosis code is set in the FCM-ECU.
|
|
|
(1)Erase the diagnosis code.
|
|
|
(2)Turn the ignition switch from "LOCK" (OFF) position to "ON" position.
|
|
|
(4)Drive the vehicle for 30 minutes.
|
|
|
(5)On completion, check that the diagnosis code is set again.
|
|
|
Q.
Is diagnosis code No. C2262 set?
|
|
|
Replace the FCM-ECU (Refer to ).
|
|
|
|
|
|
Intermittent malfunction (Refer to GROUP 00 - How to Cope with Intermittent
Malfunction ).
