This diagnosis code is set if any malfunction below is found:

When the output value of the longitudinal G-sensor is abnormal

PROBABLE CAUSES

ASC-ECU malfunction
External noise interference

DIAGNOSIS PROCEDURE

STEP 1. M.U.T.-III CAN bus diagnosis

Use M.U.T.-III to diagnose the CAN bus lines.

Q. Is the check result normal?

	Go to Step 3

	Repair the CAN bus lines (Refer to GROUP 54C - CAN Bus Diagnostics Table ). On completion, go to Step 2.

STEP 2. Diagnosis code recheck after resetting CAN bus lines

Q. Is diagnosis code No.C1210 set?

	Go to Step 3

	This diagnosis is complete.

STEP 3. M.U.T.-III data list

Check the following data list (Refer to

).

Item 09: G sensor

Q. Is the check result normal?

	Go to Step 4

	Replace the hydraulic unit (integrated with ASC-ECU) (Refer to ). Then go to Step 5.

STEP 4. Check whether the diagnosis code is reset.

Erase the diagnosis code.

Q. Is diagnosis code No.C1210 set?

	Replace the hydraulic unit (integrated with ASC-ECU) (Refer to ), and then go to Step 5.

	Intermittent malfunction (Refer to GROUP 00 - How to Use Troubleshooting/How to Cope with Intermittent Malfunctions ).

STEP 5. Check whether the diagnosis code is reset.

Erase the diagnosis code.

Q. Is diagnosis code No.C1210 set?

	Return to Step 1.

	This diagnosis is complete.
