Inspection Procedures

  1. CHECK THE DTC RECONFIRMING THAT THE NORMAL CODE IS OUTPUT. 
    1. Connect the Hi-Scan (pro) with the data link connector and turn the ignition switch ON.
    2. Verify that the normal code is output.

    Is the normal code output? 

    Yes:  Go to next step.

    No:  Erase the DTC and recheck using Hi-Scan (pro).

  2. CHECK THE POWER SOURCE CIRCUIT. 
    1. Disconnect the connector from the ABS control module.
    2. Turn the ignition switch ON, measure the voltage between terminal 4 of the ABS control module harness side connector (E37) and body ground.
    • Specification: approximately B+

    Refer to the DTC troubleshooting procedures. (see DTC C1200 (FL); C1203 (FR); C1206 (RL); C1209 (RR) WHEEL SPEED SENSOR OPEN OR SHORT TO GROUND )

    OK:  Go to next step.

    NG:  Repair or replace the wheel speed sensor.

  5. CHECK THE HYDRAULIC CIRCUIT FOR LEAKAGE. 

    Refer to the hydraulic lines. (see COMPONENTS )

    OK:  Go to next step.

    NG:  Repair the hydraulic lines for leakage.

The problem is still occurring, replace the ABS control module.
