  1. 1) MEASURE THE RESISTANCE OF THE SENTRY KEY ANTENNA CIRCUIT Disconnect the Sentry Key Antenna Ring connector from the SKREEM. Turn the ignition on. Measure the resistance of the Sentry Key Antenna circuit from cavity 1 to cavity 2 of the connector. Is the resistance between 4 and 6 ohms? Yes Replace the Sentry Key Remote Entry Module. Perform «SENTRY KEY VERIFICATION TEST»(ref-250684-S22203965722007031500000) . No Replace the Sentry Key Antenna Ring assembly. Perform «SENTRY KEY VERIFICATION TEST»(ref-250684-S22203965722007031500000) .

  1. When Monitored: Continuous.
  2. Set Condition: The Sentry Key Remote Entry Module (SKREEM) reports a short to power, ground, or an open circuit failure on the Remote Keyless Entry Relay Control circuit.
POSSIBLE CAUSES
REMOTE KEYLESS ENTRY RELAY CONTROL CIRCUIT SHORTED TO VOLTAGE
REMOTE KEYLESS ENTRY RELAY CONTROL CIRCUIT SHORTED TO GROUND
REMOTE KEYLESS ENTRY RELAY CONTROL CIRCUIT OPEN

  1. 1) MEASURE THE RESISTANCE OF THE REMOTE KEYLESS ENTRY RELAY CONTROL CIRCUIT Turn the ignition off. Disconnect the SKREEM harness connector. Remove the Remote Keyless Entry Relay. NOTE: Check connectors - Clean/repair as necessary. Measure the resistance of the Remote Keyless Entry Relay Control circuit from the SKREEM harness connector to the Remote Keyless Entry Relay harness connector. Is the resistance below 5.0 ohms? Yes Go to step 2) . No Repair the Remote Keyless Entry Relay Control circuit for an open. Perform «SENTRY KEY VERIFICATION TEST»(ref-250684-S22203965722007031500000) .
  2. 2) MEASURE THE VOLTAGE OF THE REMOTE KEYLESS ENTRY RELAY CONTROL CIRCUIT Turn the ignition on. Measure the voltage of the Remote Keyless Entry Relay Control circuit at the Remote Keyless Entry Relay harness connector. Is voltage present? Yes Repair the Remote Keyless Entry Relay Control circuit for a short to voltage. Perform «SENTRY KEY VERIFICATION TEST»(ref-250684-S22203965722007031500000) . No Go to step 3) .
  3. 3) MEASURE THE RESISTANCE OF THE REMOTE KEYLESS ENTRY RELAY CONTROL CIRCUIT Turn the ignition off. Measure the resistance between ground and the Remote Keyless Entry Relay Control circuit at the Remote Keyless Entry Relay harness connector. Is the resistance below 10K ohms? Yes Repair the Remote Keyless Entry Relay Control circuit for a short to ground. Perform «SENTRY KEY VERIFICATION TEST»(ref-250684-S22203965722007031500000) . No Replace the Remote Keyless Entry Relay. Perform «SENTRY KEY VERIFICATION TEST»(ref-250684-S22203965722007031500000) .
