Condition/Concern
Some customers may comment on a Service Suspension System Message displayed on the Drivers Information
Center (DIC).
During the assembly process, it is possible that the 90 degree electrical connector at the top end of a shock absorber
(actuator) may not have been fully seated or has been bumped firmly enough to partially disconnect it, or create an
internal contact concern.
Recommendation/Instructions
Complete the following steps BEFORE attempting shock absorber (actuator) replacement.
Connector with Position Assurance (CPA) Tab (CTS Only)
2612987
CTS Models built after February 22, 2011 have a CPA tab (1) as shown above as part of the connector.
Vehicles built with this design should be less susceptible to being unseated. The CTS is the only vehicle to
adopt this design change. All other products continue with the original style connector.
1. If the diagnostic trouble code (DTC) refers to a front shock absorber (actuator), remove the front shock tower
beauty cover (if equipped on the vehicle).
Electrical Connector and Shock Absorber (Actuator) Contact
2612986
2. Disconnect the electrical connector (1) from the top of the applicable shock absorber (actuator) contact (2).
Electrical Connector Insulator and Center Post
2612985
3. Visually examine the green insulator and center post (1) of the electrical connector to assure it is straight and in
serviceable condition. Replace the connector and retest if required.
4. Reconnect the electrical connector to the shock absorber (actuator). Clear the suspension DTC and confirm that
the code does not reset.
5. If the code returns, remove the electrical connector from the shock absorber (actuator) and pigtail. Swap the
connector with the connector on the opposite side shock absorber (actuator).
6. Does the DTC follow the connector to the other side? If YES, replace the connector, if NO refer to SI and follow
the diagnostics for the DTC originally found.
