Conditions for Running the DTC

Ignition ON.

Conditions for Setting the DTC

The control module has detected a malfunction.

Action Taken When the DTC Sets

* The Side Blind Zone and Rear Cross Traffic Alert Systems will not function.

* The DIC will display "Service Side Detection System".

Conditions for Clearing the DTC

* A current DTC clears when the malfunction is no longer present.

* A history DTC clears when the control module ignition cycle counter reaches the reset threshold of 50, without a repeat of the malfunction.

Diagnostic Aids

If DTC B094B 58 or B094C 58 is set, check for anything that can interfere with the radar signal. Verify area in front of radar is clean of mud, ice, snow, etc. Also verify the fascia panels in front of the radar are damage-free and not obstructed by any add-on accessories such as emblems, etc.
