CHECKING AFTERMARKET ACCESSORIES

Do not connect aftermarket accessories into the following circuits:

CAUTION:  Refer to SIR Caution in Service Precautions.

-

SIR circuits, all such circuits are indicated on circuit diagrams with the SIR symbol.

NOTE:  Refer to OBD II Symbol Description Notice in Service Precautions.

-

OBD II circuits, all such circuits are indicated on circuit diagrams with the OBD II symbol.

Always check for aftermarket accessories (non-OEM) as the first step in diagnosing electrical problems. If the vehicle is so equipped, disconnect the
system to verify that these add-on accessories are not the cause of the problems.

Possible causes of vehicle problems related to aftermarket accessories include:
-

Power feeds connected to points other than the battery

-

Antenna location

-

Transceiver wiring located too close to vehicle electronic modules or wiring

-

Poor shielding or poor connectors on antenna feed line

-

Check for recent service bulletins detailing installation guidelines for aftermarket accessories.
