INSPECTION PROCEDURE

NOTE: Turn the ignition switch off before measuring the resistances of CAN bus main wires and CAN bus branch wires.

PROCEDURE

1. CHECK OPEN IN CAN BUS WIRE (SKID CONTROL ECU BRANCH WIRE)
(a) Turn the ignition switch off.
(b) Disconnect the skid control ECU with actuator connector.

NG -- REPAIR OR REPLACE CAN BUS BRANCH WIRE OR CONNECTOR
OK -- Continue to next step.
2. CHECK WIRE HARNESS (IG1, GND1, GND2)

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

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

NG -- REPAIR OR REPLACE HARNESS OR CONNECTOR
OK -- REPLACE SKID CONTROL ECU WITH ACTUATOR
