Special Tools Required

J 43241  Keyless Entry Tester

Circuit/System Verification

1. Place the remote-key on the test pad of the J 43241   and press each button of the remote-key one at a time. The tester should sound a tone and

illuminate a green light when each button is pressed.

‹› If one or more buttons does not sound the tone and illuminate the green light, replace the remote-key battery and retest with the J 43241  . If

the condition continues after battery replacement, replace the remote-key.

2. Verify the scan tool Transponder Key parameter for the appropriate remote-key is Programmed.

‹› If not the specified value, program the remote-key. Refer to Replacing Keys   (See: Accessories and Optional Equipment/Antitheft and Alarm

Systems/Service and Repair).

3. Operate the remote-key while observing the scan tool Remote Key Function parameters. The parameter should correspond with the function

selected on the remote-key.

‹› If the parameter does not match the function selected on the remote-key, program the remote-key and retest. Refer to Replacing Keys   (See:

Accessories and Optional Equipment/Antitheft and Alarm Systems/Service and Repair). If the condition continues after remote-key
programming, replace the remote-key.

4. If all circuits test normal, replace the CIM.

Repair Instructions

Perform the Diagnostic Repair Verification   (See: Powertrain Management/Computers and Control Systems/Testing and Inspection/Diagnostic Trouble
Code Tests and Associated Procedures/Verification Tests and Procedures) after completing the diagnostic procedure.
