Actuator Power Source Circuit: Procedure

1. Remove the TI & TE fuse from the main body ECU RH (cowl side J/B RH).
2. Measure the resistance of the TI & TE fuse.

   Standard resistance

   Below 1 Ω

NG → REPLACE FUSE 

OK: Go to next step 

1. Disconnect the J28 connector from the multiplex tilt & telescopic ECU.
