Door Locks & Anti-Theft Systems 3 illustrations ~3427 words

DESCRIPTION

Remote Keyless Entry (RKE) system, also known as Remote Function Actuator (RFA) system, allows driver to operate several features from outside vehicle. Main components of system are the transmitter and receiver module. Transmitter unit sends a radio signal to the receiver module in response to button presses by vehicle operator. Receiver module then interprets signals and relays information to appropriate module to provide requested function. RFA module identifies which transmitter is being used and sends class 2 data to memory seat module to adjusts seats and mirrors to their preset positions. Perimeter lighting can be enabled to illuminate using RKE transmitter when it is dark out.

OPERATION

Pressing unlock button once will unlock driver's door, turn on illuminated entry lights, and disarm theft system (if equipped). Pressing unlock button a second time within 4 seconds will unlock all doors. This function will be disabled if ignition is on.

Pressing lock button will lock all doors. Pressing trunk button will unlock trunk. This feature is disabled if transmission is not in Park and ignition is on. Pressing fuel door button will open fuel door.

SYNCHRONIZING TRANSMITTERS

When transmitters are out of synchronization, all buttons except fuel door release will be inoperative. Transmitters need to be synchronized if buttons have been pushed 256 times out of range of receiver, Remote Function Actuator (RFA) module is replaced or resynchronization procedure is performed outside range of receiver.

To synchronize transmitters after battery replacement, press and hold LOCK and UNLOCK buttons simultaneously for seven seconds. All doors lock and unlock to indicate synchronization is complete. Verify RKE system operation.

PRELIMINARY CHECKS

Ensure retained accessory power system operates correctly by checking if radio operates after ignition is turned off for 10 minutes or until door is opened. Check if door locks work from all door lock switches. Ensure theft deterrent arming and disarming functions correctly. See appropriate ANTI-THEFT SYSTEMS article. Check IGN SW fuse No. 20 (15-amp) in rear compartment fuse block and replace as necessary. Ensure all power and ground circuits are clean and tight. Perform REMOTE KEYLESS ENTRY (RKE) SYSTEM CHECK .

Scan Tool

A scan tool can be used to retrieve and clear DTCs. The scan tool also has several features that can be used to help locate an intermittent condition. When scan tool is used for system tests, it will display values actually seen or commanded by various systems (i.e., BCM, PCM). To display DTCs, connect scan tool to Data Link Connector (DLC) and power up scan tool. Select appropriate system for DTCs to be displayed. Select DTC on scan tool to display system DTCs. After displaying all DTCs, go to REMOTE KEYLESS ENTRY SYSTEM DTCs table to diagnose and repair. To clear DTCs, see CLEARING DIAGNOSTIC TROUBLE CODES (DTCs) .

On-Board Diagnostics

DTCs can be displayed and erased on both digital and analog instrument clusters using the A/C-heater control panel. Turn ignition on. On digital instrument clusters, press and hold OFF and warmer (Red) buttons until all segments in the Driver's Information Center (DIC) light up. On analog instrument clusters, press and hold OFF and passenger warmer (up arrow) buttons until all segments in the Driver's Information Center (DIC) light up. On all models, after segments light up, the DIC will display DTCs in the following order

  1. PCM
  2. IPC

  4. SDM
  5. TCS
  6. PZM
  7. IRC
  8. RFA
  9. CCP

REMOTE KEYLESS ENTRY (RKE) DIAGNOSTIC SYSTEM CHECK

  1. Connect scan tool to Data Link Connector (DLC). Turn ignition on. Attempt to establish communications with vehicle. If scan tool communicates with vehicle, go to next step. If scan tool does not communicate with vehicle, go to BODY CONTROL MODULES - DEVILLE & ELDORADO article.
  2. Attempt to communicate with Remote Function Actuator (RFA) module. If scan tool communicates with RFA module, go to next step. If scan tool does not communicate with RFA module, go to «REMOTE KEYLESS ENTRY SYSTEM INOPERATIVE»(/cadillac/deville-concours/i-final-1999-1999/remont/door-locks-anti-theft-systems/#remote-keyless-entry-systems__remote-keyless-entry-system-inoperative) .
  3. Check for Diagnostic Trouble Codes (DTCs) in RFA module. If any current RKE DTCs are present, go to «REMOTE KEYLESS ENTRY SYSTEM DTCs»(/cadillac/deville-concours/i-final-1999-1999/remont/door-locks-anti-theft-systems/#remote-keyless-entry-systems) table. If no DTCs are set, go to «REMOTE KEYLESS ENTRY (RKE) SYSTEM CHECK»(/cadillac/deville-concours/i-final-1999-1999/remont/door-locks-anti-theft-systems/#remote-keyless-entry-systems__remote-keyless-entry-rke-system-check) under TROUBLE SHOOTING.

Remote Function Actuator (RFA) module runs this internal self-test at power up. This test will only be run if DTC B1982 (battery voltage high) or B1983 (battery voltage low) is not present.

DTC B1000 will set and store in Remote Keyless Entry (RKE) current memory only if RFA module fails internal Read Only Memory (ROM) to Random Access Memory (RAM) write test. No driver warning message will be displayed for this DTC.

DTC B1000 will clear when RFA module receives a "passed test" message after power up self-test.

Testing

  1. If remote keyless entry diagnostic system check was performed, go to next step. If remote keyless entry diagnostic system check was not performed, go to «REMOTE KEYLESS ENTRY (RKE) DIAGNOSTIC SYSTEM CHECK»(/cadillac/deville-concours/i-final-1999-1999/remont/door-locks-anti-theft-systems/#remote-keyless-entry-systems__remote-keyless-entry-rke-diagnostic-system) under SELF-DIAGNOSTIC SYSTEM.
  2. Using scan tool, clear DTC B1000. Turn ignition off and back on again. Recheck for DTCs. If DTC B1000 is still present, go to next step. If DTC B1000 is no longer present, go to «REMOTE KEYLESS ENTRY (RKE) DIAGNOSTIC SYSTEM CHECK»(/cadillac/deville-concours/i-final-1999-1999/remont/door-locks-anti-theft-systems/#remote-keyless-entry-systems__remote-keyless-entry-rke-diagnostic-system) under SELF-DIAGNOSTIC SYSTEM.
  3. Replace Remote Function Actuator (RFA) module. See «REMOTE FUNCTION ACTUATOR (RFA) MODULE»(/cadillac/deville-concours/i-final-1999-1999/remont/door-locks-anti-theft-systems/#remote-keyless-entry-systems) under REMOVAL & INSTALLATION.

Diagnostic Aids

DTC B1000 will stay in current memory until passed test message is received by Remote Function Actuator (RFA) module after power up self-test. If DTC will not clear, replace RFA module.

Remote Function Actuator (RFA) module performs internal tests on EEPROM each time RFA module writes to memory in EEPROM. RFA module reads back data from EEPROM that has been written to EEPROM. If data does not match after 3 consecutive write and verify attempts, RFA module will set DTC B1007 as current. No driver warning message will be displayed for this DTC.

DTC B1007 will clear when RFA successfully writes and reads from EEPROM. History DTCs will clear after 50 consecutive ignition cycles if malfunction is no longer present.

  1. If remote keyless entry diagnostic system check was performed, go to next step. If remote keyless entry diagnostic system check was not performed, go to «REMOTE KEYLESS ENTRY (RKE) DIAGNOSTIC SYSTEM CHECK»(/cadillac/deville-concours/i-final-1999-1999/remont/door-locks-anti-theft-systems/#remote-keyless-entry-systems__remote-keyless-entry-rke-diagnostic-system) under SELF-DIAGNOSTIC SYSTEM.
  2. Using scan tool, clear DTC B1007. Turn ignition off and back on again. Recheck for DTCs. If DTC B1007 is still present, go to next step.

  3. Replace Remote Function Actuator (RFA) module. See «REMOTE FUNCTION ACTUATOR (RFA) MODULE»(/cadillac/deville-concours/i-final-1999-1999/remont/door-locks-anti-theft-systems/#remote-keyless-entry-systems) under REMOVAL & INSTALLATION.

EEPROM cannot be removed from Remote Function Actuator (RFA) module. DTC B1007 is an internal RKE malfunction, RFA module will need to be replaced if DTC B1007 is set as current.

Remote Function Actuator (RFA) module runs this test every time module processes a message from transmitters.

DTC B3108 will set and store in current memory if RFA module does not receive a transmission from transmitter. No driver warning message will be displayed for this DTC.

Under all fault conditions, DTC B3108 will clear when transmission is received by RFA module, using on-board clearing DTC feature or when scan tool is used to clear codes.
