- Disconnect connector C2 from the radio interface module (RIM).
- Remove the radio.
- Disconnect the radio connector.
- Test the LH side audio (+) circuit (radio connector terminal E13
or RIM terminal B4) for a short to voltage. (Turn ON the ignition, leaving
the engine OFF, when testing for a short to voltage.)
- Test the LH side audio (+) circuit for a short to ground. Refer
to
Testing for Short to Ground
in
Wiring Systems.
- Test the shield wire circuit (radio connector terminal E14) for
a short to voltage.
Did you find and correct a short to voltage or ground condition?
