TROUBLESHOOTING HINTS (The most likely causes for these DTCs are to set are:)
The CAN bus line is defective. Malfunction of the hydraulic unit (integrated with TCL/ASC-ECU) Malfunction of the steering wheel sensor
DIAGNOSIS Required Special Tools:
MB991958: Scan Tool (MUT-III Sub Assembly)
MB991824: Vehicle Communication Interface (V.C.I.) MB991827: MUT-III USB Cable MB991910: MUT-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.
1. Connect scan tool MB991958 to the data link connec
tor. NOTE: For a past trouble, you may not find it by the MUT-III
CAN bus diagnostics even if there is any failure in CAN
bus lines. In this case, Refer to HOW TO COPE WITH
INTERMITTENT MALFUNCTIONS
). and check the CAN
bus lines. You can narrow down the possible cause of
the trouble by referring to the DTC, which is set
regarding the CAN communication-linked ECUs (Refer
to HOW TO DIAGNOSE THE CAN BUS LINE
).

2. Turn the ignition switch to "ON" position.
3. Diagnose the CAN bus line.
Q: Is the check result satisfactory?
YES: Go to Step 2
NO: Repair the CAN bus lines (Refer to DIAGNOSTIC TROUBLE
CODE DIAGNOSIS
or DIAGNOSIS < VEHICLES WITHOUT
ADVANCED AIR BAG
). On completion, go to Step 6.
STEP 2. Using scan tool MB991958, read the steering wheel sensor
diagnostic trouble code.
Check if a steering wheel sensor DTC is set.
Q: Is the DTC set?
YES: Diagnose the steering wheel sensor by referring to DIAGNOSTIC
TROUBLE CODE CHART
.
NO: Go to Step 3.
STEP 3. Using scan tool MB991958 read any of the diagnostic trouble
code.
Check if a DTC, which relates to CAN communication-linked systems below,
is set.

DTC U1105: YR/G CAN TIMEOUT/NOT EQUIPPED CIRCUIT OPERATION The TCL/ASC-ECU and the G and yaw rate sensor are connected each other via
CAN bus line, and the sensor sends longitudinal and lateral acceleration
information to the ECU. TCL/ASC DTC SET CONDITIONS
Current trouble
Connector(s) or wiring harness in the CAN bus lines between the TCL/ASC-
ECU and the G and yaw rate sensor, the power supply system to the G and yaw
rate sensor, the G and yaw rate sensor itself, or the TCL/ASC-ECU may be
defective.
Past trouble
Carry out diagnosis with particular emphasis on connector(s) or wiring harness
in the CAN bus lines between the G and yaw rate sensor and the TCL/ASC-
ECU, and the power supply system to the G and yaw rate sensor. For diagnosis
procedures, refer to HOW TO COPE WITH INTERMITTENT MALFUNCTIONS
). CAUTION: If DTC U1105 is set in the TCL/ASC-ECU, always
diagnose the CAN bus lines.
CAUTION: Whenever the ECU is replaced, ensure that the CAN
bus lines are normal.
