STEP 6. Check whether the DTC is reset.
Erase the DTCs.
Q: Is DTC U0100 or U0141 set?

YES : Replace the hydraulic unit (integrated with ABS-ECU)

(Refer to

P.35B-188

).

NO : The procedure is complete.

DTC U1415 Variant coding not completed

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

).

• When the DTC U1415 is set in ABS-ECU, the DTC may

also be set in ETACS-ECU. When the DTC is set in
ETACS-ECU, carry out the diagnosis of the DTC for
ETACS-ECU first.

.

OPERATION

• ABS-ECU receives the vehicle information stored in the

ETACS-ECU via CAN bus lines.

• The ABS-ECU stores the tire size information sent from the

ETACS.

.

DTC SET CONDITIONS

This DTC is set when the tire size information is not coded to
the ABS-ECU.

.

PROBABLE CAUSES

• Variant coding for ETACS-ECU has not been implemented.

• Malfunction of ABS-ECU.

DIAGNOSIS

Required Special Tools:

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

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

• 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 MB991958 to diagnose the CAN bus lines.
Q: Is the check result normal?

YES : Go to Step 2.
NO : Repair the CAN bus lines (Refer to GROUP 54C

−

CAN Bus Diagnostics Table

P.54C-17

). On

completion, go to Step 4.

STEP 2. Scan tool other system DTC
Use scan tool MB991958 to check that the DTC B222C is set in
the ETACS-ECU.
Q: Is any DTC set?

YES : Troubleshoot the relevant DTC, and then go to Step

4.

NO : Go to Step 3.

STEP 3. Check whether the DTC is reset.
(1) Erase the DTC.
(2) Turn the ignition switch to the "ON" position.
(3) Turn the ignition switch to the "OFF" position.
(4) Check that the ABS warning light goes out when the ignition

switch is turned to the "ON" position.

Q: Is the DTC U1415 set?

YES : Replace the hydraulic unit (integrated with ABS-ECU)

(Refer to

P.35B-188

). Then go to Step 4.

NO : Intermittent malfunction (Refer to GROUP 00

− How

to Use Troubleshooting/How to Cope with Intermittent
Malfunctions

P.00-15

).

STEP 4. Check whether the DTC is reset.
(1) Erase the DTC.
(2) Turn the ignition switch to the "ON" position.
(3) Turn the ignition switch to the "OFF" position.
(4) Check that the ABS warning light goes out when the ignition

switch is turned to the "ON" position.

Q: Is the DTC U1415 set?

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

DTC U1417 Variant coding value invalid (includes faulty installation)

CAUTION

• If DTC U1417 is set in ABS-ECU, always diagnose the

CAN bus lines. If there is any fault in the CAN bus lines
(Refer to GROUP 54C

− CAN Bus Line Diagnostic Flow

P.54C-10

), an incorrect DTC may be set. In this case,

the set DTC is not highly reliable.

• Before replacing the ECU, ensure that the communica-

tion circuit is normal.

• When the DTC U1417 is set in ABS-ECU, the DTC may

also be set in ETACS-ECU. When the DTC is set in
ETACS-ECU, carry out the diagnosis of the DTC for
ETACS-ECU first.

.

OPERATION

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

DTC SET CONDITIONS

ABS-ECU communicates with ETACS-ECU via CAN bus lines.
This DTC is set when there is difference between the vehicle
information from the ETACS-ECU and the vehicle information
stored in the ABS-ECU.

.

PROBABLE CAUSES

• Malfunction of ETACS-ECU

• ETACS-ECUs have been interchanged between two vehi-

cles.

• ABS-ECU malfunction

• External noise interference

• ABS-ECUs have been interchanged between two vehicles.

DIAGNOSIS

Required Special Tools:

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

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

• 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 MB991958 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

−

). On

completion, go to Step 2.

STEP 2. DTC recheck after resetting CAN bus lines
Q: Is the DTC U1417 set?

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

STEP 3. Scan tool other system DTC
Use scan tool MB991958 to check whether the
ETACS-ECU-related or engine control module-related DTC is
set or not.
Q: Is any DTC set?
