2010 Cadillac CTS Sedan AWD V6-3.6L Page 565
Circuit/System Description
The rear compartment keyless entry antenna is used to establish low frequency (LF) communications with the keyless entry transmitter. As a
vehicle with a closed rear compartment lid is approached with a keyless entry transmitter, known as an electronic key, and the rear compartment lid
release switch is pressed, the keyless entry antenna transmitter broadcasts a challenge to the transmitter in an approximate 1 meter range. If the
response from the transmitter via radio frequency (RF) is valid, the latched rear compartment will be passively unlocked/unlatched, allowing the
rear compartment area to be opened.
Conditions for Running the DTC
The rear compartment lid release switch is pressed.
Conditions for Setting the DTC
An improper current level is seen on the keyless entry antenna - signal 3 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.
