Standard resistance:

Below 1 Ohms

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

2. CHECK WIRE HARNESS (TERMINAL BW)

(a) Turn the ignition switch ON.





(b) Check the voltage between the terminal of the wire harness side connector and the body ground.

Standard voltage:





NG -- REPAIR OR REPLACE HARNESS AND CONNECTOR (P/W FUSE - MASTER SWITCH)
OK -- Continue to next step.
