.
STEP 2. Using scan tool MB991958 read the diagnostic trouble code.
Check if a DTC, which relates to CAN communication-linked systems below,
is set.
Power train control module
DTC U1102: ABS-ECU time-out
Combination meter DTC 018: ABS-ECU time-out
Q: Is the DTC set?
YES: Go to Step 3.
NO: Go to Step 4.
STEP 3. Recheck for diagnostic trouble code.
Recheck if the DTC is set.
1. Erase the DTC.
2. Turn the ignition switch to "ON" position.
3. Check if the DTC is set.
Q: Is the check result satisfactory?
YES: A poor connection, open circuit or other intermittent malfunction is
present in the CAN bus lines between the G and yaw rate sensor and the
TCL/ASC-ECU (Refer to HOW TO COPE WITH INTERMITTENT MALFUNCTIONS
).
NO: Replace hydraulic unit (integrated with TCL/ASC-ECU) and then go
to Step 4.
STEP 4. Recheck for diagnostic trouble code.

TECHNICAL DESCRIPTION (COMMENT) If the scan tool (MUT-III Sub Assembly) can not communicate with the ABS
system, the CAN bus lines may be defective. If the ABS system does not work, the
TCL/ASC-ECU or its power supply circuit may be defective. TROUBLESHOOTING HINTS (The most likely causes for this case:)
Damaged wiring harness or connector Malfunction of the hydraulic unit (Integrated with TCL/ASC-ECU)
DIAGNOSIS Required Special Tools:
MB991958: Scan Tool (MUT-III Sub Assembly)
MB991824: Vehicle Communication Interface (V.C.I.)

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
MB991952: ABS Check Harness
STEP 1. Measure the voltage at TCL/ASC-ECU connector A-32.
1. Disconnect the connector A-32, and connect special tool ABS Check
Harness (MB991952) to the wiring harness-side connector.
2. Turn the ignition switch to the "ON" position.
3. Measure the voltage between terminal 32 and ground. It should measure
approximately 12 volts (battery positive voltage). NOTE: Do not connect special tool ABS Check Harness
(MB991952) to the TCL/ASC-ECU.

NO: Repair or replace the damaged component(s). Then go to Step 8.
STEP 3. Measure the resistance at TCL/ASC-ECU connector A-32.
1. Disconnect the connector A-32, and connect special tool ABS Check
Harness (MB991952) to the wiring harness-side connector.
2. Measure the resistance between terminal 12, 34 and ground. It should be 2
ohms or less. NOTE: Do not connect special tool ABS Check Harness
(MB991952) to the TCL/ASC-ECU.

CIRCUIT OPERATION
The steering wheel sensor is energized by the ignition switch (IG2) through
multi-purpose fuse 13 and the steering wheel sensor terminal 2. If the power supply to the steering wheel sensor has failed, scan tool (MUT-III
Sub Assembly) will not be able to communicate with it.
TROUBLESHOOTING HINTS (The most likely causes for this case:)
Damaged wiring harness or connector Defective battery Charging system failed 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. Measure the voltage at G and yaw rate sensor connector C-36.
1. Disconnect the G and yaw rate sensor connector C-36, and measure at the
harness side connector.
2. Turn the ignition switch to the "ON" position.
3. Measure the voltage between terminal 1 and body ground.
Voltage should measure battery positive voltage (approximately 12
volts
).
