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)
1
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
2.
Disconnect the electrical connector (1) from the top of the applicable shock absorber (actuator) contact (2).
Electrical Connector Insulator and Center Post
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.

GM bulletins are intended for use by professional technicians, NOT a "do-it-yourselfer". They are written to inform these technicians of conditions that may
occur on some vehicles, or to provide information that could assist in the proper service of a vehicle. Properly trained technicians have the equipment, tools,
safety instructions, and know-how to do a job properly and safely. If a condition is described, DO NOT assume that the bulletin applies to your vehicle, or that
your vehicle will have that condition. See your GM dealer for information on whether your vehicle may benefit from the information.
