INSPECTION PROCEDURE

PROCEDURE

1. INSPECT FUSE (TI & TE)
(a) Remove the TI & TE fuse from the main body ECU RH.
(b) Measure the resistance of the fuse.
Standard resistance:
Below 1 Ohms
NG -- REPLACE FUSE
OK -- Continue to next step.
2. CHECK WIRE HARNESS (MULTIPLEX TILT AND TELESCOPIC ECU - BATTERY)





(a) Disconnect the K27 connector from the multiplex tilt and telescopic ECU.
(b) Measure the voltage according to the value(s) in the table below.
Standard voltage:






NG -- CHECK WIRE HARNESS (MULTIPLEX TILT AND TELESCOPIC ECU - MAIN BODY ECU RH)
OK -- Continue to next step.
3. CHECK WIRE HARNESS (MULTIPLEX TILT AND TELESCOPIC ECU - BODY GROUND) B2610

NG -- REPAIR OR REPLACE HARNESS OR CONNECTOR
OK -- PROCEED TO NEXT CIRCUIT INSPECTION SHOWN IN PROBLEM SYMPTOMS TABLE
4. CHECK WIRE HARNESS (MULTIPLEX TILT AND TELESCOPIC ECU - MAIN BODY ECU RH)





(a) Disconnect the DA connector from the main body ECU RH.
(b) Measure the resistance according to the value(s) in the table below.
Standard resistance:






NG -- REPAIR OR REPLACE HARNESS OR CONNECTOR (MULTIPLEX TILT AND TELESCOPIC ECU - MAIN BODY ECU RH)
OK -- REPAIR OR REPLACE HARNESS OR CONNECTOR (BATTERY - MAIN BODY ECU RH)
