Important: The voltage signal sent by the 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 |
5 | Test the passive portion of the transmitter:
Does the J 43241 beep during each entry attempt? | Go to Step 8 | Go to Step 9 |
6 | Test both the Keyless Entry Antenna power and ground circuit for an open or short to ground. Refer to Circuit Testing and Wiring Repairs in Wiring Systems. Did you find and correct the condition? | Go to Step 14 | Go to Step 8 |
7 | Inspect for poor connections at the affected Keyless Entry Antenna. Refer to Testing for Intermittent Conditions and Poor Connections and Connector Repairs in Wiring Systems. Did you find and correct the condition? | Go to Step 14 | Go to Step 12 |
8 | Inspect for poor connections at the Remote Control Door Lock Receiver (RCDLR). Refer to Testing for Intermittent Conditions and Poor Connections and Connector Repairs in Wiring Systems. Did you find and correct the condition? | Go to Step 14 | Go to Step 13 |
