Important: The voltage signal sent by the remote control door lock receiver (RCDLR) to the passive antenna is a AC voltage signal. The DMM must be set on AC voltage setting to record the voltage pulse to the passive antenna. Important: Use a DMM to record the voltage pulse using the MIN MAX setting to capture the AC voltage pulse to the passive antenna. Important: The ignition start button must be pressed to produce the voltage pulse to the passive antenna.
Was an AC voltage signal captured on the DMM? | Go to Step 7 | Go to Step 6 |
