INSPECTION PROCEDURE 

1. INSPECT DLC3 TERMINAL VOLTAGE (Ts TERMINAL) 
   1. Turn the ignition switch to the ON position.
   2. Measure the voltage according to the value(s) in DLC3 TERMINAL VOLTAGE (Ts TERMINAL)  .

   Standard: 

   DLC3 TERMINAL VOLTAGE (Ts TERMINAL)
   
   

   Tester Connection	Condition	Specified Condition
   D3-12 (Ts) - D3-4 (CG)	IG switch ON	10 to 14 V

   NG: Go to step 3 

   OK: Go to next step 

2. CHECK HARNESS AND CONNECTOR (SKID CONTROL ECU - DLC3) 
   1. Check the harness and connector between the skid control ECU and DLC3.

   NG: REPAIR OR REPLACE HARNESS OR CONNECTOR (TS CIRCUIT) 

   OK: REPLACE BRAKE ACTUATOR ASSY (See step 3 in REPLACEMENT  ) 

3. CHECK HARNESS AND CONNECTOR (DLC3 - BODY GROUND) 
   1. Measure the resistance according to the value(s) in DLC3 - BODY GROUND  .

   Standard: 

   DLC3 - BODY GROUND
   
   

   Tester Connection	Specified Condition
   D3-4 (CG) - Body ground	Below 1

   NG: REPAIR OR REPLACE HARNESS OR CONNECTOR (GND CIRCUIT) 

   OK: Go to next step 

4. CHECK HARNESS AND CONNECTOR (SKID CONTROL ECU - DLC3) 
   1. Check the harness and connector between the skid control ECU and DLC3.

   NG: REPAIR OR REPLACE HARNESS OR CONNECTOR (TC CIRCUIT) 

   OK: REPLACE BRAKE ACTUATOR ASSY (See step 3 in  REPLACEMENT  )
