  1. Ignition OFF, disconnect the harness connector at the T10N keyless entry antenna-passenger door handle.
  2. Test for less than 5 Ω between the ground circuit terminal 4 and ground.
    • If greater than the specified range, test the gorund circuit for an open/high resistance.
  3. Ignition ON, verify the scan tool Exterior Passenger Door Handle Touch Sensor parameter is Inactive.
    • If not the specified value, test the signal circuit terminal 3 for a short to ground. If the circuit tests normal, replace the K84 keyless entry control module.
  4. Connect a 3A fused jumper wire between the signal circuit terminal 3 and ground, verify the scan tool Exterior Passenger Door Handle Touch Sensor is Active.
    • If not the specified value, test the signal circuit for a short to voltage or an open/high resistance. If the circuit tests normal, replace the K84 keyless entry control module
  5. If all circuits test normal, test or replace the T10N keyless entry antenna-passenger door handle.
