Circuit/System Verification

2022 Chevrolet Traverse High Country, FWDSECTION Circuit/System Verification
  1. Verify the Tire Pressure Monitoring System is functioning by adding air to one tire to see the air pressure display increase.
    • Go to next step: If the pressure increases 
  2. Verify the VIN information for the vehicle transmitter is correct using the EL-52545  .
    • If the VIN is incorrect 

      This transmitter is not for this vehicle, it may already be programmed to work with a different vehicle but cannot be programmed to this vehicle.

    • Go to next step: If the VIN is correct 
  3. Verify the frequency of the transmitter matches the frequency of the tire pressure monitoring system and the remote control door lock receiver using the EL-52545  .
    • If the transmitter frequency is incorrect 

      Replace the vehicle transmitter.

    • Go to next step: If the transmitter frequency is correct 
  4. Verify the part number information for the vehicle transmitter is correct using the EL-52545  .
    • If the vehicle transmitter part number is incorrect 

      Replace the vehicle transmitter.

    • Go to next step: If the vehicle transmitter part number is correct 
  5. Verify the transmitter output is above 20% on the EL-52545  signal strength meter by pressing a button on the transmitter ten times.
    • If the transmitter output is lower than 20% 

      Replace the transmitter battery.

      • NOTE:

      Before replacing the transmitter, inspect the transmitter battery contacts for any corrosion or damage. If no corrosion or damage is found, replace the transmitter battery and retest before replacing the transmitter. For transmitter battery replacement refer to Remote Keyless Entry (RKE) System Operation in the owner manual.

    • Go to next step: If the transmitter output is higher than 20% 
  6. Using the scan tool read the number of transmitters learned in the K9 Body Control Module. Using the EL-52545  read the number of transmitters learned in the transmitter.
    • Go to next step: If the transmitters learned is equal to the number programmed 
  7. Lock the vehicle using the keyless entry transmitter.
    • If either the doors or the rear compartment do not unlock/unlatch and open 

      Refer to Circuit/System Testing.

    • Go to next step: If both doors and the rear compartment unlock/unlatch and open 
  8. The concern may be caused by temporary RF interference. Discuss the conditions in which the concern occurs with the customer. RF interference from aftermarket devices such as 2-way radios, power inverters, cellular phone chargers, computers, etc. may cause a system malfunction. High RF traffic areas, such as gas stations which use pay-at-the-pump RF transponders, may also cause interference that could lead to a malfunction.
