INSPECTION PROCEDURE

PROCEDURE

1. INSPECT FUSE (TI & TE)

(a) Remove the TI & TE fuse from the main body ECU RH (cowl side J/B RH).

(b) Measure the resistance of the TI & TE fuse.

Standard resistance:

Below 1 Ohms

NG -- REPLACE FUSE
OK -- Continue to next step.

2. CHECK HARNESS AND CONNECTOR (MULTIPLEX TILT & TELESCOPIC ECU - BATTERY)

(a) Disconnect the J28 connector from the multiplex tilt & telescopic ECU.





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

Standard voltage:





NG -- CHECK HARNESS AND CONNECTOR (MULTIPLEX TILT & TELESCOPIC ECU - MAIN BODY ECU RH)
OK -- Continue to next step.

3. CHECK HARNESS AND CONNECTOR (MULTIPLEX TILT & TELESCOPIC ECU - BODY GROUND)

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





Standard resistance:





NG -- REPAIR OR REPLACE HARNESS OR CONNECTOR

OK -- PROCEED TO NEXT CIRCUIT INSPECTION SHOWN IN PROBLEM SYMPTOMS TABLE

4. CHECK HARNESS AND CONNECTOR (MULTIPLEX TILT & TELESCOPIC ECU - MAIN BODY ECU RH)

(a) Disconnect the RA connector from the main body ECU RH (cowl side J/B 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 & TELESCOPIC ECU - MAIN BODY ECU RH)

OK -- REPAIR OR REPLACE HARNESS OR CONNECTOR (BATTERY - MAIN BODY ECU RH (COWL SIDE J/B RH))
