Code No.C2003: Control parameter not implement

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, Trouble code diagnosis ).
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.
If diagnosis code No.C2003 is set in ASC-ECU, always diagnose the CAN bus line. If there is any fault in the CAN bus lines, an incorrect diagnosis code may be set. In this case, the set diagnosis code is not highly reliable.
Before replacing the ECU, ensure that the communication circuit is normal.
When diagnosis code No.C2003 is set in ASC-ECU, the diagnosis code may also be set in ETACS-ECU. When the diagnosis code is set in ETACS-ECU, carry out the diagnosis of the diagnosis code for ETACS-ECU first.
When the hydraulic unit (integrated with ASC-ECU) is replaced, always carry out the calibration of the steering wheel sensor, the G and yaw rate sensor and brake fluid pressure sensor (Refer to , and ).

OPERATION

ASC-ECU receives the vehicle information stored in the ETACS-ECU via CAN bus lines.

DIAGNOSIS CODE SET CONDITIONS

When received unset coding data from the ETACS-ECU, this diagnosis code is set.

PROBABLE CAUSES

Malfunction of ETACS-ECU
Engine ECU malfunction
ETACS-ECUs have been interchanged between two vehicles.
ASC-ECU malfunction
ASC-ECUs have been interchanged between two vehicles.
ETACS-ECU or ASC-ECU installation error
Malfunction of ETACS-ECU coding data

DIAGNOSIS PROCEDURE

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 3.

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

STEP 2. Diagnosis code recheck after resetting CAN bus lines

Q. Is diagnosis code No.C2003 set?

	Go to Step 3.

	This diagnosis is complete.

STEP 3. M.U.T.-III other system diagnosis code

Use M.U.T.-III to check whether the ETACS-ECU-related diagnosis code is set or not.

Q. Is the diagnosis code set?

	Troubleshoot for the relevant diagnosis code.

	Go to Step 4.

STEP 4. Check part number of ASC-ECU

Check the part number of ASC-ECU.

Q. Is the check result normal?

	Go to Step 5.

	Replace the ASC-ECU (Refer to ). Then go to Step 8.

STEP 5. ETACS-ECU coding data check

Q. Is the check result normal?

	Go to Step 6.

	Replace the ETACS-ECU (Refer to GROUP 54A - ETACS-ECU ).

STEP 6. Check part number of ETACS-ECU

Check the part number of ETACS-ECU.

Q. Is the check result normal?

	Go to Step 7.

	Replace the ETACS-ECU (Refer to GROUP 54A - ETACS-ECU ).

STEP 7. Check whether the diagnosis code is reset.

Q. Is diagnosis code No.C2003 set?

	Replace the hydraulic unit (ASC-ECU) (Refer to ). Then go to Step 8.

	The trouble can be an intermittent malfunction (Refer to GROUP 00 - How to Cope with Intermittent Malfunction ).

STEP 8. Check whether the diagnosis code is reset.

Q. Is diagnosis code No.C2003 set?

	Return to Step 1.

	This diagnosis is complete.
