Malfunction of the hydraulic unit (integrated with TCL/ASC-ECU)
Past trouble
Carry out diagnosis with particular emphasis on connector(s) or wiring harness
in the power supply circuit (terminal 11) to the TCL/ASC-ECU solenoid valve
or ground circuit (terminal 12). For diagnosis procedures, refer to HOW TO COPE WITH INTERMITTENT MALFUNCTIONS
).
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
MB991970: ABS Check Harness
STEP 1. Using scan tool MB991958, diagnose the CAN bus line.
1. Connect scan tool MB991958 to the data link connec
tor. CAUTION: To prevent damage to scan tool MB991958,
always turn the ignition switch to the
"LOCK" (OFF) position before connecting or
disconnecting scan tool MB991958.

4. Turn the ignition switch to the "LOCK" (OFF) position.
Q: Is DTC C1226, C1231, C1236, C1241, C1246, C1251, C1256, C1261,
C1300, C1305, C1310 or C1315 set?
YES: Go to Step 3.
NO: The procedure is complete.
STEP 3. 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 11 and ground. It should be
a
pproximatel
y 12 volts
(batter
y positive volta
ge). NOTE: Do not connect special tool ABS Check Harness
(MB991952) to the TCL/ASC-ECU.

Q: Is TCL/ASC-ECU connector A-32 damaged?
YES: Repair or replace the damaged component(s). Then go to Step 5.
NO: An open or short circuit may be present in the solenoid valve power
supply circuit. Repair the wiring harness between TCL/ASC-ECU
connector A-32 terminal 11 and fusible link No. 3. Then go to Step 4.
STEP 5. 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 and ground. It should be 2
ohms or less. NOTE: Do not connect special tool ABS Check Harness
(MB991952) to the TCL/ASC-ECU.

Q: Is TCL/ASC-ECU connector A-32 damaged?
YES: Repair or replace the damaged component(s). Then go to Step 8.
NO: An open circuit may be present in the ground circuit. Repair the
wiring harness between TCL/ASC-ECU connector A-32 terminal 12 and
the body ground. Then go to Step 8.
STEP 7. Recheck for diagnostic trouble code.
Check again if the DTC is set.
1. Turn the ignition switch to the "ON" position.
2. Erase the DTC.
3. Turn the ignition switch to the "LOCK" (OFF) position.
4. Turn the ignition switch to the "ON" position.
5. Check if the DTC is set.
