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 (Refer to GROUP 54C -
Troubleshooting
 ).
- 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.
- When the ACC/FCM-ECU is replaced, calibrate the radar (refer to ).
|
OPERATION
ACC/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
- Malfunction of the CAN bus line
- Malfunction of the column switch assembly (Integrated with steering wheel sensor)
- Malfunction of the ACC/FCM-ECU
|
|
STEP 1. M.U.T.-III CAN bus diagnostics.
|
|
|
Use M.U.T.-III to perform the CAN bus diagnosis.
|
|
|
Q.
Is the check result normal?
|
|
|
 Go to Step 2.
|
|
|
|
|
|
 Repair the CAN bus lines (Refer to GROUP 54C -
Troubleshooting ).
On completion, go to Step 2.
|
|
|
|
|
|
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.
|
|
|
Q.
Is the diagnosis code set?
|
|
|
Troubleshoot the steering wheel sensor diagnosis code.
|
|
|
|
|
|
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.
|
|
|
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 degree
angle from the neutral position.
|
|
|
- Item No. 07: 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 ACC/FCM-ECU.
|
|
|
(1)Erase the diagnosis code.
|
|
|
(2)Turn the ignition switch from "LOCK" (OFF) position to "ON" position.
|
|
|
(4)Press the FCM and UMS ON/OFF switch to turn the FCM system to ON.
|
|
|
(5)Drive the vehicle for 30 minutes.
|
|
|
(6)On completion, check that the diagnosis code is set again.
|
|
|
Q.
Is diagnosis code No. C2262 set?
|
|
|
Replace the ACC/FCM-ECU (Refer to ).
|
