INSPECTION PROCEDURE

PROCEDURE

1. INSPECT FUSE (POWER)





(a) Remove POWER fuse from the driver side J/B.
(b) Check continuity of the POWER fuse.
Standard resistance:
Below 1 Ohms (Continuity)
NG -- REPLACE FUSE
OK -- Continue to next step.
2. CHECK HARNESS AND CONNECTOR (MULTIPLEX TILT AND TELESCOPIC ECU - BATTERY)





(a) Disconnect the multiplex tilt and telescopic ECU connector.
(b) Measure the voltage between terminals +B and GND of the ECU connector.
Standard voltage:
10 to 14 V
NG -- REPAIR OR REPLACE HARNESS OR CONNECTOR
OK -- Continue to next step.
3. CHECK HARNESS AND CONNECTOR (MULTIPLEX TILT AND TELESCOPIC ECU - BODY GROUND)





(a) Measure the resistance between terminal GND of the ECU connector and body ground.
Standard resistance:
Below 1 Ohms
NG -- REPAIR OR REPLACE HARNESS OR CONNECTOR
OK -- PROCEED TO NEXT CIRCUIT INSPECTION SHOWN IN PROBLEM SYMPTOMS TABLE
