6. Turn the ignition switch to the "LOCK" (OFF) position.
Q: Is DTC C1266, C1273, or C1274 set?
YES: Go to Step 3.
NO: The procedure is complete.
STEP 3. Measure the voltage 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. Turn the ignition switch to the "ON" position.
3. Measure the voltage between terminal 19 and ground. It should be
a
pproximatel
y 12 volts
(batter
y positive volta
ge). NOTE: Do not connect special tool ABS Check Harness
(MB991970) to the ABS-ECU.

YES: Repair or replace the damaged component(s). Then go to Step 8 .
NO: An open or short circuit may be present in the solenoid valve power
supply circuit. Repair the wiring harness between ABS-ECU connector A-
02 terminal 19 and fusible link No.3. Then go to Step 8 .
STEP 5. 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 terminal 18 and ground. It should be 2
ohms or less. NOTE: Do not connect special tool ABS Check Harness
(MB991970) to the ABS-ECU.
