STEP 3. Check whether the DTC is reset.
Erase the DTC.
Q: Is DTC C2002 set?

YES : Return to Step 1.
NO : The procedure is complete.

DTC C2003: Control parameter not implement

CAUTION

• If there is any problem in the CAN bus lines, an incor-

rect diagnostic trouble code may be set. Prior to this
diagnosis, diagnose the CAN bus lines (Refer to
GROUP 54C

− CAN Bus Line Diagnostic Flow

P.54C-10

).

• If diagnostic trouble 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 diagnostic trouble
code may be set. In this case, the set diagnostic trouble
code is not highly reliable.

• Before replacing the ECU, ensure that the communica-

tion circuit is normal.

• When diagnostic trouble code C2003 is set in

ASC-ECU, the diagnostic trouble code may also be set
in ETACS-ECU. When the diagnostic trouble code is set
in ETACS-ECU, carry out the diagnosis of the diagnos-
tic trouble code for ETACS-ECU first.

• When the hydraulic unit (integrated with ASC-ECU) is

replaced, always carry out the calibration of the steer-
ing wheel sensor, the G and yaw rate sensor and brake
fluid pressure sensor (Refer to

P.35C-282

,

P.35C-283

and

P.35C-284

).

.

DTC SET CONDITIONS

ASC-ECU communicates with ETACS-ECU via CAN bus lines.
When received unset vehicle information from the
ETACS-ECU, this diagnostic trouble code is set.

.

PROBABLE CAUSES

• ETACS-ECU or ASC-ECU which was equipped with other

vehicle is used.

• Faulty installation of ETACS-ECU or ASC-ECU

• Faulty ETACS-ECU coding

• Malfunction of ETACS-ECU

• ASC-ECU malfunction

DIAGNOSIS

Required Special Tools:

• MB991958: Scan Tool (M.U.T.-III Sub Assembly)

• MB991824: Vehicle Communication Interface (V.C.I.)

DIAGNOSIS

• MB991827: M.U.T.-III USB Cable

• MB991910: M.U.T.-III Main Harness A

STEP 1. Using scan tool MB991958, diagnose the CAN bus
line.
Use scan tool to diagnose the CAN bus lines.
Q: Is the check result normal?

YES : Go to Step 3.
NO : Repair the CAN bus lines (Refer to GROUP 54C

−

CAN Bus Diagnostics Table

P.54C-17

). On

completion, go to Step 2.

STEP 2. Diagnostic trouble code recheck after resetting
CAN bus lines
Q: Is DTC C2003 set?

YES : Go to Step 3.
NO : The procedure is complete.

STEP 3. Scan tool other system DTC
Use scan tool to check whether any coding-related diagnostic
trouble code is set by ETACS-ECU.
Q: Is the DTC set?

YES : Troubleshoot for the relevant diagnostic trouble code

(Refer to GROUP 54A

− ETACS-ECU/Diagnostic

Trouble Code Chart

P.54A-732

). Then go to Step 8.

NO : 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?

YES : Go to Step 5.
NO : Replace the hydraulic unit (integrated with ASC-ECU)

(Refer to

P.35C-287

). Then go to Step 8.
