INSPECTION PROCEDURE
NOTE: When replacing the skid control ECU, perform initialization of linear solenoid valve and calibration Initialization.

PROCEDURE

1. INSPECT DLC3 (TC AND CG TERMINAL)

(a) Turn the ignition switch on.
(b) Measure the voltage according to the value(s) in the table below.
Voltage:

NG -- CHECK HARNESS AND CONNECTOR (DLC3 (TC) TO HV CONTROL ECU)
OK -- Continue to next step.
2. CHECK CAN COMMUNICATION SYSTEM
(a) Check if the CAN communication DTC is output Diagnosis System.
Result:

HINT: If troubleshooting has been carried out according to the PROBLEM SYMPTOMS TABLE, refer back to the table and proceed to the next step before replacing the part Problem Symptoms Table.

B -- REPAIR CIRCUIT INDICATED BY OUTPUT CODE
A -- Continue to next step.
3. CHECK HARNESS AND CONNECTOR (DLC3 (TC) TO HV CONTROL ECU)

(a) Disconnect the HV control ECU connector.
(b) Measure the resistance according to the value(s) in the table below.
Resistance:

NG -- REPAIR OR REPLACE HARNESS OR CONNECTOR
OK -- Continue to next step.
4. CHECK HARNESS AND CONNECTOR (DLC3 (CG) TO BODY GROUND)

(a) Measure the resistance according to the value(s) in the table below.
Resistance:

NG -- REPAIR OR REPLACE HARNESS OR CONNECTOR
OK -- Continue to next step.
5. CHECK ECM (DLC3 (TC) INPUT)
SST: 09843-18040

(a) Using the SST, connect terminals TC and CG of the DLC3.
(b) Check that the engine warning light is blinking.
Result:

B -- REPAIR OR REPLACE HARNESS OR CONNECTOR
A -- Continue to next step.
6. CHECK CAN COMMUNICATION SYSTEM
(a) Check if the CAN communication DTC is output Diagnosis System.
Result:
