InspectionNJEL0221AUDIO UNITNJEL0221S01All voltage inspections are made with:
Ignition switch ON or ACC
Audio unit ON
Audio unit connected (If audio unit is removed for inspection, supply a ground to the case using a jumper
wire.)
ANTENNANJEL0221S02Using a jumper wire, clip an auxiliary ground between antenna and body.
If reception improves, check antenna ground (at body surface).
If reception does not improve, check main feeder cable for short circuit oropen circuit.
