Test B: Keyless Entry System Inoperative

  1. Check the 10A Electron Bat fuse located in the interior fuse panel. Is the fuse okay? If yes, go to next step. If no, go to  3 .
  2. Check the 30A Power Window fuse located in the left engine compartment fuse panel. Is the fuse okay? If yes, go to step  5 . If no, go to next step.
  3. Turn key to OFF position. Replace the fuse(s) in question. Turn key to ON position. Operate the keyless entry system. Turn key to OFF position. Inspect the fuse(s). Do(es) the fuse(s) fail again? If yes, go to next step. If no, go to step  5 .
  4. Turn key to OFF position. Remove the blown fuse(s). Disconnect the keyless entry module 20-pin input and 8-pin output connectors located behind the left inner kick panel. Measure the resistance of the Purple wire between the left side of the 10A Electron Bat fuse holder and ground. See WIRING DIAGRAMS  . Measure the resistance of the Blue/White wire between the terminal nearest the battery at the 30A Power Window fuse holder and ground. Are any of the resistances less than 5 ohms? If yes, service the wire(s) in question for short(s) to ground. If no, install fuses and go to next step.
  5. Turn key to OFF position. Disconnect the keyless entry module input and output connectors. Turn key to ON position. Measure the voltage on the Purple wire between the keyless entry module input connector and ground. Measure the voltage on the Light Green wire between the keyless entry module output connector and ground. Is each voltage greater than 10 volts? If yes, go to step  8 . If no and the Purple wire has less than 10 volts, service the wire for open(s) between the keyless entry module and the interior fuse panel. See WIRING DIAGRAMS  . If no and the Light Green wire has less than 10 volts, go to next step.
  6. Turn key to OFF position. Remove the right circuit breaker located behind the interior fuse panel. See COMPONENT LOCATIONS  . Measure the voltage on the White/Blue wire between the right circuit breaker connector and ground. Is the voltage greater than 10 volts? If yes, go to next step. If no, service the White/Blue wire for open(s) between the circuit breaker and the left engine compartment fuse panel.
  7. Turn key to OFF position. Remove the right circuit breaker. Measure the resistance between terminals of the circuit breaker. Is the resistance less than 5 ohms? If yes, service the Light Green wire for open(s) between the circuit breaker and the keyless entry module and then go to next step. If no, replace circuit breaker. See RIGHT CIRCUIT BREAKER  .
  8. Turn key to OFF position. Disconnect the keyless entry module input and output connectors. Measure the resistance of the Black wire between the keyless entry module and ground. Measure the resistance of the Black wire between the keyless entry module output connector and ground. Are both of the resistances less than 5 ohms? If yes, go to next step. If no, service Black wire. See WIRING DIAGRAMS  .
  9. Turn key to OFF position. Disconnect the keyless entry keypad connector located in the driver side door. Measure the resistance of the Black wire between the keypad connector and ground. Is the resistance less than 5 ohms? If yes, go to TEST A: KEYLESS ENTRY SYSTEM FUNCTION TEST  . If the keyless entry system is still completely inoperative, replace the keyless entry module. See KEYLESS ENTRY MODULE  under REMOVAL & INSTALLATION. If no, service the Black wire for open(s).
