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.
