Below 1 Ω

NG: REPLACE FUSE

OK: Go To Next Step
CHECK POWER WINDOW REGULATOR MASTER SWITCH ASSEMBLY (CPUB, SIG VOLTAGE)
1. Turn the ignition switch OFF.
2. Measure the voltage between terminals CPUB, SIG, BDR and GND.
Standard voltage:

10 to 14 V

OK: PROCEED TO NEXT CIRCUIT INSPECTION SHOWN ON PROBLEM SYMPTOMS TABLE

NG: Go To Next Step
