INSPECTION PROCEDURE

PROCEDURE

1. INSPECT DLC3 (TC TERMINAL VOLTAGE)

(a) Turn the ignition switch to ON.





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

Standard Voltage:





(c) Turn the ignition switch off.

NG -- CHECK HARNESS AND CONNECTOR (DLC3 - BODY GROUND)
OK -- Continue to next step.

2. CHECK CAN COMMUNICATION SYSTEM

(a) Check if the CAN communication DTC is output Diagnosis System.

Result





B -- REPAIR CIRCUITS INDICATED BY OUTPUT DTCS Vehicle Stability Control System (for Hydraulic Brake Booster)

A -- REPLACE MASTER CYLINDER SOLENOID Disassembly

3. CHECK HARNESS AND CONNECTOR (DLC3 - BODY GROUND)

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





Standard Resistance:





NG -- REPAIR OR REPLACE HARNESS OR CONNECTOR
OK -- Continue to next step.

4. CHECK HARNESS AND CONNECTOR (ECM - DLC3)

(a) Disconnect the ECM connector.





(b) Measure the resistance according to the value(s) in the table below.

Standard Resistance:





(c) Reconnect the ECM connector.

NG -- REPAIR OR REPLACE HARNESS OR CONNECTOR
OK -- Continue to next step.

5. CHECK HARNESS AND CONNECTOR (ECM - SKID CONTROL ECU)

(a) Disconnect the S1 skid control ECU connector.





(b) Disconnect the E14 ECM connector.

(c) Measure the resistance according to the value(s) in the table below.

Standard Resistance:





(d) Reconnect the ECM connector.

(e) Reconnect the skid control ECU connector.

NG -- REPAIR OR REPLACE HARNESS OR CONNECTOR
OK -- Continue to next step.

6. CHECK ECM (DLC3 (TC) INPUT)

(a) Connect terminals TC and CG of DLC3.





(b) Turn the ignition switch to ON.

(c) Check if the ECM warning light is blinking.

OK:

ECM warning light is blinking.

(d) Turn the ignition switch off.

(e) Disconnect the TC and CG terminals of DLC3.

NG -- REPLACE ECM Removal

OK -- REPLACE MASTER CYLINDER SOLENOID Disassembly
