Inspection Procedure
NOTE:
When replacing the skid control ECU, perform initialization of linear solenoid valve and calibration (see INITIALIZATION
).
- CHECK DLC3 (TC VOLTAGE)
- Turn the power switch ON (READY).
- Measure the voltage of the DLC3 connector.
Standard voltage
STANDARD VOLTAGE SPECIFICATIONTester Connection Specified Condition D1-13 (TC) - Body ground 10 to 14 V - Measure the resistance of the DLC3 connector.
Standard resistance
STANDARD RESISTANCE REFERENCE CHARTTester Connection Specified Condition D1-4 (CG) - Body ground Below 1 Ω
NG: Go to step 3
OK: Go to next step
- CHECK CAN COMMUNICATION SYSTEM
- Check if a CAN communication system DTC is output (See PROBLEM SYMPTOMS TABLE
)
.
Result
DTC RESULT REFERENCEResult Proceed to DTC is not output A DTC is output B
B: REPAIR CIRCUIT INDICATED BY OUTPUT CODE
A: REPLACE SKID CONTROL ECU
- Check if a CAN communication system DTC is output (See PROBLEM SYMPTOMS TABLE
)
.
- CHECK WIRE HARNESS AND CONNECTORS (DLC3 - ECM)
- Disconnect the slid control ECU connector.
- Measure the resistance of the wire harness side connectors.
Standard resistance
STANDARD RESISTANCE REFERENCE CHARTTester Connection Specified Condition D1-13 (TC) - E6-14 (TC) Below 1 Ω D1-13 (TC) - Body ground 10 kΩ or higher
NG: REPAIR OR REPLACE HARNESS AND CONNECTOR
OK: Go to next step
- CHECK WIRE HARNESS (DLC3 - BODY GROUND)
- Measure the resistance of the DLC3 connector.
Standard resistance
STANDARD RESISTANCE REFERENCE CHARTTester Connection Specified Condition D1-4 (CG) - Body ground Below 1 Ω
NG: REPAIR OR REPLACE HARNESS AND CONNECTOR
OK: Go to next step
- Measure the resistance of the DLC3 connector.
- CHECK CAN COMMUNICATION SYSTEM
- Check if a CAN communication system DTC is output (See PROBLEM SYMPTOMS TABLE
)
.
