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))
