Diagnostic Aids

WARNING: This page is about a different car, the 2008 Cadillac STS. However, it is still accessible from the selected car via links, so may be relevant.

For the J 43241  , inspect the keyless entry transmitter part number to determine that it is the correct model for the vehicle. See Special Tools . A wrong model transmitter may pass the test, but it will not activate the vehicle remote system.
