Remote Keyless Entry Systems: Other Dodge Ram Van B2500

PROGRAMMING

Note. Following procedures require a functional transmitter. If a functional transmitter is not available, program RKE receiver using scan tool. See appropriate BODY CONTROL COMPUTER TESTS article.

Note. For more information, see TSB REMOTE KEYLESS ENTRY (RKE) PROGRAMMING PROCEDURES .

CENTRAL TIMER MODULE PROGRAMMING

Note. This procedure applies to models with anti-theft system.

This procedure requires the use of a scan tool. Using scan tool, select CENTRAL TIMER MODULE. If scan tool displays NO RESPONSE or CCD BUS FAILURE, go to appropriate VEHICLE COMMUNICATIONS article. If scan tool does not display NO RESPONSE or CCD BUS FAILURE, use scan tool to select MISCELLANEOUS, then PROGRAM RKE. Follow scan tool prompts to program transmitter.

POWER LOCK/REMOTE KEYLESS ENTRY MODULE

Note. This procedure applies to models without anti-theft system.

1. Locate Dark Green program enable wire, connected to Data Link Connector (DLC) terminal No. 1. DLC is located under left side of instrument panel, to left of steering column. End of enable wire has a Black rubber cap.
2. Connect program enable wire to ground. Turn ignition on. Power door locks will cycle. Depress either button on transmitter. Doors locks will cycle to confirm signal was received. Depress either button on second transmitter if needed. Doors locks will again cycle to confirm signal was received.
3. Disconnect enable from ground. Secure wire to harness. Turn ignition off. Verify transmitter(s) operation.

HORN CHIRP ENABLE/DISABLE PROGRAMMING

Turn ignition on, with engine off. Press and hold UNLOCK button for at least 4 seconds. While holding UNLOCK button, press LOCK button, then release both buttons. Horn will chirp once when programming is completed.

POWER LOCKS DO NOT WORK WITH RKE OR LOCK SWITCHES

Check fuses.

POWER LOCKS DO NOT WORK WITH RKE, BUT WORK WITH LOCK SWITCHES

Check RKE transmitter batteries. Program RKE transmitter. See PROGRAMMING .

POWER LOCKS WORK WITH RKE, BUT DO NOT WORK WITH LOCK SWITCHES

Check power lock switches. See appropriate POWER DOOR LOCKS & LIFTGATE RELEASE article.

ONE POWER LOCK DOES NOT WORK WITH RKE TRANSMITTER OR LOCK SWITCHES

Check power lock motor. See appropriate POWER DOOR LOCKS & LIFTGATE RELEASE article.

ANTI-THEFT FEATURES DO NOT WORK

If horn chirp does not work, check horn relay. See HORN RELAY under COMPONENT TESTS. If relay is okay or any other feature does not work, check CTM. See CENTRAL TIMER MODULE (CTM) under SYSTEM TESTS.

COMPONENT TESTS

Note. For power door lock component tests, see appropriate POWER DOOR LOCKS & LIFTGATE RELEASE article.

TRANSMITTER

Replace transmitter batteries. Reprogram suspect transmitter and a known-good transmitter. See appropriate procedure under PROGRAMMING . Test system with both transmitters. If both transmitters do not operate system, diagnose system using scan tool. See appropriate BODY CONTROL COMPUTER TESTS article. If known-good transmitter operates system but suspect transmitter does not, replace faulty transmitter. Repeat transmitter programming.

Scheme 29

1. Remove horn relay from junction block. Using an ohmmeter, check for continuity between relay terminals No. 87A and 30. (Scheme 29) If continuity does not exist, replace relay. If continuity exists, go to next step.
2. Check for continuity between relay terminals No. 30 and 87. If continuity exists, replace relay. If continuity does not exist, check resistance between relay terminals No. 85 and 86. If resistance is not 70-80 ohms, replace relay. If resistance is 70-80 ohms, go to next step.
3. Using jumper wires, connect battery voltage to relay terminal No. 86 and ground to relay terminal No. 85. Continuity should exist between terminals No. 30 and 87. Continuity should not exist between relay terminals No. 87A and 30. If continuity is not as specified, replace relay. If continuity is as specified, relay is okay.

SYSTEM TESTS

Note. For wire color and circuit identification, see WIRING DIAGRAMS .
