DIAGNOSTIC TROUBLE CODE CHART
M1136003300022
CAUTION
During diagnosis, a DTC associated with other
system may be set when the ignition switch is
turned on with connector(s) disconnected. On
completion, confirm all systems for DTC(s). If
DTC(s) are set, erase them all.
NOTE: If the ABS-8 ECU or the active wheel
speed sensor are disconnected, or if the wiring is
an open/ short circuit, the ABS 8 ECU will shut
off power supply to the respective wheel speed
sensor. All other wheel speed sensors will oper-
ate normally. To restore the power supply, the
ignition switch must be turned to the "OFF" posi-
tion then to the "ON" position again.
Follow the inspection chart that is appropriate for the
diagnostic trouble code.

DIAGNOSTIC TROUBLE CODE PROCEDURES
U1100 CAN Communications System Time Out Error Engine Related Data
CAUTION
• If DTC U1100 is set in the ABS/TCL-ECU,
always diagnose the CAN main bus line. If
there is any fault in the CAN bus lines, an
incorrect DTC may be set.
• Whenever the ABS/TCL-ECU is replaced,
ensure that the communication circuit is nor-
mal.
NOTE: If the ABS-8 ECU or the active wheel
speed sensor are disconnected, or if the wiring is
an open/ short circuit, the ABS 8 ECU will shut
off power supply to the respective wheel speed
sensor. All other wheel speed sensors will oper-
ate normally. To restore the power supply, the
ignition switch must be turned to the "OFF" posi-
tion then to the "ON" position again.
.
DTC SET CONDITION
The ABS/TCL-ECU receives engine system-related
signals from the ENGINE-ECU via CAN bus lines.
.
TROUBLESHOOTING HINTS (THE MOST
LIKELY CAUSES FOR THESE DTCS ARE
TO SET ARE:)
• Damaged harness or connector.
• Malfunction of the ENGINE-ECU.
• Malfunction of the ABS/TCL-ECU.
DIAGNOSIS
Required Special Tools:
• MB991958: Diagnostic Tool (MUT-III Sub Assembly)
• MB991824: V.C.I.
• MB991827: MUT-III USB Cable
• MB991910: MUT-III Main Harness A

STEP 1. Using diagnostic tool MB991958, diagnose the
CAN bus line.
CAUTION
To prevent damage to diagnostic tool MB991958, always
turn the ignition switch to the "LOCK" (OFF) position
before connecting or disconnecting diagnostic tool
MB991958.
(1) Connect diagnostic tool MB991958 to the data link
(2) Turn the ignition switch to the "ON" position.
(3) Diagnose the CAN bus line. (Refer to
).
(4) Turn the ignition switch to the "LOCK" (OFF) position.
(5) Disconnect diagnostic tool MB991958.
Q: Is the CAN bus line found to be normal?
YES : Go to Step 2.
NO : Repair the CAN bus line. (Refer to GROUP 54C,
Diagnosis
− Can Bus Diagnostic Chart
Then go to Step 6.
STEP 2. Using diagnostic tool MB991958, read the
diagnostic trouble code.
CAUTION
To prevent damage to diagnostic tool MB991958, always
turn the ignition switch to the "LOCK" (OFF) position
before connecting or disconnecting diagnostic tool
MB991958.
(1) Connect diagnostic tool MB991958 to the data link
(2) Turn the ignition switch to the "ON" position.
(3) Check for MPI system diagnostic trouble code. (Refer to
GROUP 13A, MPI Diagnosis
− Diagnostic Function − How
to Read and Erase Diagnostic Trouble Code
(4) Turn the ignition switch to the "LOCK" (OFF) position.
(5) Disconnect diagnostic tool MB991958.
Q: Is any DTC set?
YES : Repair the MPI control system. (Refer to GROUP
13A, MPI Diagnosis
