  1. Check ROOM fuse located in interior fuse panel. If fuse is okay, reinstall fuse and go to step 3). If fuse is blown, go to next step.

See Figure . Measure voltage between ground and RAP module connector C2, ter minal No. 12 (Blue/Red wire). See Figure . If both voltages are greater than 10 volts, go to next step. If voltages are less than 10 volts, repair wire in question. See WIRING DIAGRAM  .
  4. Measure resistance between ground and RAP module connector C2, terminal No. 14 (Black wire). See Figure . Resistance should be less than 5 ohms. If resistance is less than 5 ohms, reconnect RAP connectors and go to next step. If resistance is not less than 5 ohms, repair Black wire between RAP module connector and ground. See WIRING DIAGRAM  .
  5. Measure battery voltage of both transmitter batteries. If voltage at both batteries is greater than 2.8 volts, reassemble transmitter and go to next step. If voltage at both batteries is not greater than 2.8 volts, replace transmitter batteries.
  6. Perform programming procedure. See REMOTE TRANSMITTER  under PROGRAMMING. If programming is successful, system is okay. If programming is not successful, replace transmitter and go to next step.
