2010 Cadillac CTS Sedan AWD V6-3.6L Page 563
Circuit/System Description
The RF door handle antenna is located in the right front door handle assembly and is used to establish low frequency (LF) communications with the
keyless entry transmitter. As a vehicle with locked doors is approached with a keyless entry transmitter, known as an electronic key, and the
exterior door handle is activated, the keyless entry antenna broadcasts a challenge to the transmitter in an approximately 1 meter range. If the
response from the transmitter via radio frequency (RF) is valid, the locked door will be passively unlocked/unlatched and allow the door to be
opened.
Conditions for Running the DTC
The right front door handle is pulled.
Conditions for Setting the DTC
An improper current level is seen on the keyless entry antenna - signal (5) circuit.
Action Taken When the DTC Sets
No action is taken.
Conditions for Clearing the DTC
* A current DTC will clear when the conditions for setting the DTC are no longer present.
* A history DTC will clear after 50 malfunction free ignition cycles.
