Pinpoint Test B - Locks Do Not Operate From Remote

TRANSMITTER

1. Open trunk. Ensure antenna is installed properly. Unplug antenna from RKEM antenna connector. Inspect antenna connector and antenna for damage. If antenna is okay, reconnect it to RKEM, then go to next step. Repair or replace antenna as necessary.
2. If more than one transmitter is available, test vehicle response to each transmitter. If other transmitters do not operate locks properly, go to next step. If other transmitters operate locks properly, replace defective transmitter.
3. Examine programming connector C4 located under glove box, for presence of shorting plug. See Fig 1 . Remove shorting plug if present, then go to next step.

4. Unplug RKEM connector C2. Test for continuity between connector C4, pin No. 1 (White/Yellow wire) and No. 2 (Gray/Yellow wire). If continuity does not exist, go to next step. If continuity exists, replace shorting plug.
5. Test for continuity between connector C4, pin No. 1 (White/Yellow wire) and ground. If continuity does not exist, go to next step. If continuity exists, repair short to ground on White/Yellow wire.
6. Test for voltage on connector C4, pin No. 1 (White/Yellow wire). If voltage does not exist, go to next step. If voltage exists, repair short to voltage on White/Yellow wire.
7. Test for continuity between connector C4, pin No. 2 (Gray/Yellow wire) and ground. If continuity exists, repair short to ground on Gray/Yellow wire. If continuity does not exist, go to next step.
8. Test for voltage on connector C4, pin No. 2 (Gray/Yellow wire). If voltage does not exist, go to next step. If voltage exists, repair short to voltage on Gray/Yellow wire.
9. Attach connector C2 to RKEM. Measure voltage between connector C2, pin No. 15 (White/Yellow wire) and ground. If voltage is 4-6 volts, go to next step. If voltage is not 4-6 volts, temporarily substitute known-good RKEM, then retest system.
10. Measure voltage between connector C2, pin No. 10 (Gray/Yellow wire) and ground. If voltage is 4-6 volts, go to next step. If voltage is not 4-6 volts, temporarily substitute known-good RKEM, then retest system.
11. Attach connector C2. Measure voltage between connector C4, pin No. 1 (White/Yellow wire) and ground. If voltage is between 4 and 6 volts, go to next step. If voltage is less than 4 volts, repair open in White/Yellow wire.
12. Test for continuity between connector C4, pin No. 2 (Gray/Yellow wire) and ground. If continuity exists, go to next step. If continuity does not exist, repair open in Gray/Yellow wire.
    NOTE: PINPOINT TEST B, steps 1) and 2) MUST be performed before performing step 13).
13. Turn ignition on. Insert shorting plug into programming connector C4. If doors lock and unlock, go to next step. If doors do not lock and unlock, go to step 4).
14. Turn ignition on. Press any button on transmitter. Repeat procedure for each transmitter. If all doors lock, then unlock, go to next step. If door locks do not respond after pressing button 3 times, replace transmitter batteries, then repeat this step. If door locks still do not respond, temporarily substitute known-good RKEM, then retest system.
15. Turn ignition off. Remove shorting plug from connector C4 (if installed). If doors lock and unlock, go to PINPOINT TEST A  , and perform steps 18) to 28). If doors do not lock and unlock, temporarily substitute known-good RKEM, then retest system.
