2. Turn the ignition switch to the "ON" position.
3. Measure the voltage between the relevant signal and ground terminals in
the ABS sensor circuit and body ground. It should be less than 1V.
DTC C1201 is set: Between signal terminal 9 and body ground, and
between ground terminal 10 and body ground DTC C1206 is set: Between signal terminal 26 and body ground, and
between ground terminal 16 and body ground DTC C1211 is set: Between signal terminal 11 and body ground, and
between ground terminal 17 and body ground DTC C1216 is set: Between signal terminal 28 and body ground, and
between ground terminal 27 and body ground
Q: Does the voltage measure 1 V or less?
YES: Go to Step 9.
NO (When the voltage between terminal 9 or 10 - and body ground
measures more than 1 V): Go to Step 11 .
NO (When the voltage between terminal 26 or 16 - and body ground
measures more than 1 V): Go to Step 12 .
NO (When the voltage between terminal 11 or 17 - and body ground
measures more than 1 V): Go to Step 13 .
NO (When the voltage between terminal 28 or 27 - and body ground
measures more than 1 V): Go to Step 14 .
STEP 9. Measure the resistance at ABS-ECU connector A-02.
1. Disconnect the connector A-02, and connect special tool ABS Check
Harness (MB991970) to the wiring harness-side connector.
2. Measure the resistance between the relevant signal and ground terminals
in the ABS sensor circuit and body ground. OK if there is no continuity. DTC C1201 is set: Between signal terminal 9 and bo
dy ground, and NOTE: Do not connect special tool ABS Check Harness
(MB991970) to the ABS-ECU.

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.

6. Turn the ignition switch to the "LOCK" (OFF) position.
Q: Is DTC C1201, C1206, C1211 or C1216 set?
YES: Replace the hydraulic unit (integrated with ABS-ECU). Then go to
Step 16.
NO: It can be assumed that this malfunction is intermittent. Refer to
HOW TO COPE WITH INTERMITTENT MALFUNCTIONS
.
STEP 16. 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.

6. Turn the ignition switch to the "LOCK" (OFF) position.
Q: Is DTC C1201, C1206, C1211 or C1216 set?
YES: Go to Step 1 .
NO: The procedure is complete.

CIRCUIT OPERATION
The ABS-ECU contains the power supply circuit (terminal 1) for the solenoid
valve. The solenoid valve is energized by the valve relay, which is
incorporated in the ABS-ECU. The valve relay, which is incorporated in the ABS-ECU, is always energizing
the solenoid valve unless the initial check is in progress when the ignition
switch is turned on. The ABS-ECU activates the solenoid valve by turning on its driving transistor.
ABS DTC SET CONDITIONS These diagnostic trouble codes will be set under the cases below.
The solenoid valve is not energized even after the ABS-ECU has turned on the
driving transistor (Open circuit is present in the power supply circuit to the
ABS-ECU solenoid valve, or the valve relay has failed). The solenoid valve is not energized even after the ABS-ECU has turned on the
driving transistor (Open circuit is present in the solenoid valve circuit inside
the ABS-ECU, or the valve relay has failed). After the ABS-ECU has turned off the driving transistor, the solenoid valve
still remains energized (short in the solenoid valve circuit). When a solenoid valve failure is detected

Malfunction of the hydraulic unit (integrated with ABS-ECU)
PAST TROUBLE
Carry out diagnosis with particular emphasis on connector(s) or wiring harness
in the power supply circuit (terminal 1) to the ABS-ECU solenoid valve or
ground circuit (terminal 18). For diagnosis procedures, refer to HOW TO TREAT PAST TROUBLE
.
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.

2. Turn the ignition switch to the "ON" position.
3. Diagnose the CAN bus line.
4. Turn the ignition switch to the "LOCK" (OFF) position.
Q: Is the CAN bus line found to be normal?
YES: Go to Step 3 .
NO: Repair the CAN bus line (Refer to TCL/ASC DIAGNOSIS
, or
DIAGNOSIS < VEHICLES WITHOUT ADVANCED AIR BAG
).
Then go to Step 2.
STEP 2. Recheck for diagnostic trouble code.
1. Erase the DTC.
2. Turn the ignition switch to the "ON" position.
