Scheme 102

1. Connect scan tool MB991958 to the data link connector.
2. Turn the ignition switch to the "ON" position.
3. Select "System Select."
4. Select "ABS/ASC/ASTC" from the system list, and select the "OK" button.
5. Select "Data List."

CHECK OF FREEZE FRAME DATA

The freeze frame data can be checked by using the scan tool.

When detecting fault and storing the DTC, the ECU connected to CAN bus line obtains the data before the determination of the DTC and the data when the DTC is determined, and then stores the ECU status of that time. By analyzing each data from scan tool, the troubleshooting can be performed more efficiently. The displayed items are as the table below.

DISPLAY ITEM LIST

FAIL-SAFE FUNCTIONS

ASC-ECU constantly monitors the input and output signals. If an error is detected in the system, ASC-ECU sends a fail signal and the corresponding indicator light is illuminated or blinks. Various controls are processed depending on the cause of malfunction as shown below.

Scheme 104

ECU TERMINAL CONDITIONS

Scheme 105

1. When performing the continuity check, turn the ignition switch to LOCK (OFF) position, connect the special tool ASC check harness (MB991997) as shown in the illustration, and disconnect the ASC-ECU connector.
2. Check for continuity between terminals shown in the chart below.
3. Terminal layout is shown in the illustration.

WHEEL SPEED SENSOR OUTPUT CURRENT MEASUREMENT

Required Special Tools

1. MB991709: Wiring harness set

The relevant wheel, on which the wheel speed sensor is fitted, should be free to run.

Scheme 106

1. Remove the wheel speed sensor connector to be checked. CAUTION: For precise measurement, do not connect to the wheel speed sensor-side connector and the wiring harness side connector terminal No. 1.
2. Use the special tool test harness (MB991709) to connect a multimeter between the wheel speed sensor-side connector and the wiring harness connector terminal No. 2.
3. Turn the ignition switch to the "ON" position. CAUTION: Do not rotate the wheel too quickly. Output current changes significantly as the wheel speed detection magnetic encoder comes near or goes away from the wheel speed sensor.
4. Rotate the wheel, on which the wheel speed sensor is fitted, quite slowly to measure the output current with the multimeter. Standard value: 5.9 to 8.4 mA or 11.8 to 16.8 mA
5. If the measurement is not within the standard value, or the output current does not change in proportion to the wheel rotation, replace the wheel speed sensor (Refer to «WHEEL SPEED SENSOR»(ref-592559-S19740126892014011000000) ).

Scheme 107

1. Raise the vehicle using a jack and support the specified points with a rigid rack. CAUTION: Before connecting or disconnecting scan tool, always turn the ignition switch to the LOCK (OFF) position.
2. Before setting scan tool, turn the ignition key to the LOCK (OFF) position.
3. Confirm that the selector lever is in the "N" position, and then start the engine.
4. When carrying out the actuator tests No. 01 to 04, perform the actuator tests using scan tool while depressing the brake pedal. When carrying out the actuator tests No. 05 to 08, perform the actuator tests using scan tool without depressing the brake pedal. When carrying out the actuator tests, rotate the wheel by hands to confirm that the braking force changes. NOTE: While performing the actuator test, the ABS warning light flashes at a rate of 2 Hz. When ASC-ECU is disabled due to the fail-safe function, the scan tool actuator test cannot be performed. After the actuator test has been performed, the ABS warning light, brake waning light, and ASC OFF light or ASC OFF display illuminate until the ignition switch is turned to ON again or the communication between scan tool and ASC-ECU is terminated.
5. This is indicated as shown in the Illustration above.

Clogged hydraulic circuit in the hydraulic unit Replace the hydraulic unit assembly.
7. After the inspection, turn the ignition switch to the LOCK (OFF) position, and then disconnect scan tool.

IN THE EVENT OF A DISCHARGED BATTERY

If the engine is started using a booster cable when the battery is completely flat, and the vehicle is then driven without waiting for the battery to be recharged, the engine may misfire and it may not be possible to drive the vehicle. This is because the ASC consumes a large amount of current when carrying out its initial checks. If this happens, recharge the battery fully.
