Inspection Procedure

WARNING: This page is about a different car, the 2007 Toyota Land Cruiser. However, it is still accessible from the selected car via links, so may be relevant.

PERFORM ACTIVE TEST BY INTELLIGENT TESTER (SHOCK ABSORBER)
1. Using the same method as used for the DAMPING FORCE CONTROLLING CHECK (see TEST MODE PROCEDURE ), bounce the vehicle and check that the shock absorber damping force becomes harder.
OK: REPLACE SUSPENSION CONTROL ECU

NG: GO TO NEXT STEP
CHECK WIRE HARNESS (DAMPING FORCE CONTROL ACTUATOR (FRONT AND REAR) - SUSPENSION CONTROL ECU)
NG: REPAIR OR REPLACE HARNESS AND CONNECTOR

OK: GO TO NEXT STEP

INSPECT DAMPING FORCE CONTROL ACTUATOR (FRONT AND REAR)

Disconnect the damping force control actuator connector.

Measure the resistance between each terminal of the damping force control actuator.

Standard resistance

TESTER CONNECTION SPECIFIED CONDITION

Tester Connection	Specified Condition
1 - 2	12.0 to 13.6 Ω
2 - 3	12.0 to 13.6 Ω
2 - 4	12.0 to 13.6 Ω
2 - 5	12.0 to 13.6 Ω

NG: REPLACE DAMPING FORCE CONTROL ACTUATOR (FRONT OR REAR)
