2. Measure the voltage according to the value(s) in the table below.

   Voltage

   Tester Connection	Condition	Specified Condition
   K16-12 (TS) - K16-4 (CG)	Engine switch on (IG)	10 to 14 V

3. Turn the engine switch off.
4. Measure the resistance according to the value(s) in the table below.

   Resistance

   Tester Connection	Specified Condition
   K16-4 (CG) - Body ground	Below 1 Ω

NG → See step   4 

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.

   Resistance (for 1UR-FSE)

   Tester Connection	Specified Condition
   A13-25 (TS) - K16-12 (TS)	Below 1 Ω
   K16-12 (TS) - Body ground	10 kΩ or higher

   Resistance (for 2GR-FSE)

   Tester Connection	Specified Condition
   K93-13 (TS) - K16-12 (TS)	Below 1 Ω
   K16-12 (TS) - Body ground	10 kΩ or higher

NG → REPAIR OR REPLACE HARNESS OR CONNECTOR (TS TERMINAL CIRCUIT) 

OK: Go to next step 

1. Check if the CAN communication system DTC is output. Refer to DTC CHECK / CLEAR .

   Result

   Result	Proceed to
   DTC is not output	A
   DTC is not output (when troubleshooting accordance with the PROBLEM SYMPTOMS TABLE)	B
   DTC is output	C

C → REPAIR CIRCUIT INDICATED BY OUTPUT CODE 

B → PROCEED TO NEXT CIRCUIT INSPECTION SHOWN IN  PROBLEM SYMPTOMS TABLE 

A → REPLACE ABSORBER CONTROL ECU 

1. Disconnect the skid control ECU connector.

   Resistance

   Tester Connection	Specified Condition
   K16-4 (CG) - Body ground	Below 1 Ω

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

OK: Go to next step 

1. Using the SST, connect the terminals TS and CG of the DLC3.

   Result	Proceed to
   Warning lights are blinking	A
   Warning lights are not blinking	B

B → CHECK BRAKE CONTROL SYSTEM (TS TERMINAL CIRCUIT) 

A: Go to next step 

1. Check if the CAN communication system DTC is output. Refer to DTC CHECK / CLEAR .

   Result

   Result	Proceed to
   DTC is not output	A
