1. NG: CHECK FOR SHORT IN ALL HARNESS AND CONNECTOR CONNECTED TO FUSE AND REPLACE FUSE 
2. OK: GO TO NEXT STEP. 

1. Disconnect the skid control ECU connector.
2. Measure the voltage according to the value (s) in the table below.

   Standard:

1. NG: REPAIR OR REPLACE HARNESS OR CONNECTOR (+BS CIRCUIT) 
2. OK: GO TO NEXT STEP. 

1. Disconnect the skid control ECU connector.
2. Measure the resistance according to the value (s) in the table below.

   Standard: 

   SKID CONTROL ECU TERMINALS RESISTANCE
   
   

   Tester Connection	Specified Condition
   S1-32 (GND1) - Body ground	Below 1 Ω

1. NG: REPAIR OR REPLACE HARNESS OR CONNECTOR (GND CIRCUIT) 
2. OK: GO TO NEXT STEP. 

HINT: These codes are detected when a problem is determined in the ABS & TRACTION actuator assy.

The ABS solenoid relay is in the ABS & TRACTION actuator assy.

Therefore, solenoid relay circuit inspection relay unit inspection cannot be performed. Be sure to check if the DTC code is output before replacing the ABS & TRACTION actuator assy.

1. Clear the DTCs (see DTC CHECK/CLEAR ).
2. Turn the ignition switch to the ON position.

Are the same DTCs recorded? 

1. NO: END 

   HINT: These DTCs may be memorized due to a malfunction in the connector terminal.

2. YES: GO TO NEXT STEP. 

   REPLACE ABS & TRACTION ACTUATOR ASSY (SEE  REPLACEMENT  )
