DTC Descriptor

DTC B094C

Right Side Object Detection Control Module

For symptom byte information, refer to Symptom Byte List .

Circuit/System Description

B218R Side Object Sensor Module - Right communicates on a private communication data bus with the B218L Side Object Sensor Module - Left. The B218L Side Object Sensor Module - Left is the master and can set this code if the B218R Side Object Sensor Module - Right determines it has an internal fault. DTC U18A6 will set if the left module is unable to communicate with the right side module.

Conditions for Running the DTC

Ignition ON.

Conditions for Setting the DTC

The B218R Side Object Sensor Module - Right has detected an internal malfunction.

Action Taken When the DTC Sets

• The side object sensor system is disabled..
• 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 40, without a repeat of the malfunction.

Diagnostic Aids

• The modules are not identical and cannot be swapped from side to side.
• This DTC may be stored as a history DTC without affecting the operation of the B218R Side Object Sensor Module - Right.
• Do not replace B218R Side Object Sensor Module - Right based only on DTC B094C being set in history.
• If DTC B094C is set as current, replace the B218R Side Object Sensor Module - Right.
• B218R Side Object Sensor Module - Right communicates on a private communication data bus with the B218L Side Object Sensor Module - Left. If programming is needed for module replacement, you must program B218L Side Object Sensor Module - Left which will then in turn program B218R Side Object Sensor Module - Right.
