Diagnostic Aids

WARNING: This page does not describe the selected car, but rather 8 other vehicles, including the 2008 GMC Yukon XL, 2008 GMC Yukon, 2008 Chevrolet Tahoe, 2008 Chevrolet Suburban, and 2008 Chevrolet Avalanche. However, it is still accessible from the selected car via links, so may be relevant.

For the J 43241  Keyless Entry Tester, 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.
