INSPECTION PROCEDURE

PROCEDURE

1. INSPECT FUSE (TI & TE)
(a) Remove the TI & TE fuse from the driver side junction block.
(b) Measure the resistance of the fuse.
Standard resistance:
Below 1 Ohms
NG -- REPLACE FUSE
OK -- Continue to next step.
2. CHECK WIRE HARNESS (ECU - BATTERY AND BODY GROUND)




(a) Disconnect the T8 ECU connector.
(b) Measure the voltage of the wire harness side connector.
Standard voltage:





(c) Measure the resistance of the wire harness side connector.
Standard resistance:






NG -- REPAIR OR REPLACE HARNESS AND CONNECTOR
OK -- REPLACE MULTIPLEX TILT AND TELESCOPIC ECU
