INSPECTION PROCEDURE

PROCEDURE

1. INSPECT DLC3 TERMINAL VOLTAGE (TS TERMINAL)





(a) Turn the ignition switch to the ON position.
(b) Measure the voltage.

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





(a) Disconnect the skid control ECU connector.
(b) Measure the resistance.
Standard Resistance:





(c) Reconnect the skid control ECU connector.
NG -- REPAIR OR REPLACE HARNESS OR CONNECTOR
OK -- REPLACE BRAKE ACTUATOR
3. CHECK HARNESS AND CONNECTOR (BODY GROUND - DLC3)





(a) Measure the resistance.
Standard Resistance:





NG -- REPAIR OR REPLACE HARNESS OR CONNECTOR
OK -- Continue to next step.
4. CHECK HARNESS AND CONNECTOR (SKID CONTROL ECU - DLC3)





(a) Disconnect the skid control ECU connector.
(b) Measure the resistance.
Standard Resistance:





(c) Reconnect the skid control ECU connector.
