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+

   Is the voltage within specification? 

   Yes:  Go to next step.

   No:  Check the harness or connector between the No.11 fuse (10A) in the passenger compartment junction block and the ABS control module. Repair if necessary.

3. CHECK THE GROUND CIRCUIT. 
   1. Disconnect the connector from the ABS control module.
   2. Check for continuity between terminals 8, 24 of the ABS control module harness side connector (E37) and ground point (G17).

   Is there continuity?

   Yes:  Go to next step.

   No:  Repair an open in the wire and ground point (G17).

4. CHECK THE WHEEL SPEED SENSOR CIRCUIT. 

   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.
