INSPECTION PROCEDURE

NOTICE:
When replacing the brake actuator assembly, perform zero point calibration Component Tests and General Diagnostics.

PROCEDURE

1. CHECK DLC3 (TC VOLTAGE)

(a) Turn the ignition switch to ON.





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

Standard Voltage:





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

2. CHECK CAN COMMUNICATION SYSTEM

(a) Check if a CAN communication system DTC is output How to Proceed With Troubleshooting.

Result:





B -- REPAIR CIRCUIT INDICATED BY OUTPUT DTC CAN Communication System

A -- REPLACE BRAKE ACTUATOR ASSEMBLY Removal

3. CHECK HARNESS AND CONNECTOR (DLC3 - ECM)

(a) Turn the ignition switch off.





(b) Disconnect the ECM connector.

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

Standard Resistance:

for 2GR-FE:





for 2AR-FE:





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

4. 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.

5. CHECK CAN COMMUNICATION SYSTEM

(a) Check if a CAN communication system DTC is output How to Proceed With Troubleshooting.

Result:





B -- REPAIR CIRCUIT INDICATED BY OUTPUT DTC CAN Communication System

A -- REPLACE BRAKE ACTUATOR ASSEMBLY Removal
