Pinpoint Test A - Locks Do Not Operate From Keypad
- Ensure key is not in ignition and that all doors are securely closed. Lock doors using keypad. If doors do not lock, go to next step.
- Turn ignition on. Open and close any door. Ensure door ajar light is on with door open and off with door closed. If light does not operate properly, repair door ajar light circuit.
- Disconnect lock control module 12-pin connector. Using ohmmeter, measure resistance between harness connector Blue/Orange wire and mating terminal of control module. Resistance should be less than 5 ohms with key in ignition switch and more than 10 k/ohms with key removed from ignition switch. If resistances are not as specified, go to next step. If resistances are okay, reconnect 12-pin connector and go to step 5).
- Disconnect ignition key reminder switch connector. Measure resistance of Blue/Orange wire between 12-pin connector and ignition key reminder switch connector. Measure resistance of Blue/Orange wire between 12-pin connector and ground. If resistance is less than 5 ohms between connectors and more than 10 k/ohms between 12-pin connector and ground, replace ignition key reminder switch. If resistances are not as specified, repair Blue/Orange wire.
- Press any button on keyless entry keypad. Ensure that keypad illuminates. Wait about 6 seconds for keypad light to go off and press next button. Repeat until all buttons have been checked. If one or more buttons do not illuminate, go to next step. If all buttons do not illuminate, go to PINPOINT TEST C . If all buttons illuminate as each is pressed, go to step 7).
- Disconnect keypad connector in driver's door. Measure resistance between terminals listed in BUTTON TERMINAL IDENTIFICATION
table. With any button depressed, resistance should be less than 5 ohms. With no buttons depressed, resistance should be more than 10 k/ohms. See Fig 1
. If resistances are okay, go to next step. If resistances are not as specified, replace keypad.BUTTON TERMINAL IDENTIFICATION
Buttons Depressed Terminals No. 1/2 1&7 3/4 2&7 5/6 3&7 7/8 4&7 9/10 5&7 - Disconnect keypad connector in driver's door. Disconnect 16-pin control module connector. Measure resistance of all keypad connector wires, except Pink and Black, between keypad connector and module connector. Measure resistance of same wires between 16-pin module connector and ground. If resistance is less than 5 ohms between connectors and more than 10 k/ohms between connector and ground, replace control module. If resistances are not as specified, repair wire(s).
