Transmitter/Module Isolation Test

  1. Connect Tech 1 to Data Link Connector (DLC). Set Tech 1 to monitor signals received by Remote Accessory Control (RAC) module. Press any transmitter button. If Tech 1 does not indicate signal received by RAC module, replace transmitter.
  2. If Tech 1 does indicate signal received by RAC module, check RAC module connector for good terminal contact. If terminal is okay, replace RAC module.
