From To
Cadillac CTS 2014 2017

This service update should be performed on vehicles in dealer inventory only. Involved vehicles are marked “open” on the Investigate Vehicle History screen in GM Global Warranty Management system. This site should always be checked to confirm vehicle involvement prior to beginning any required inspections and/or repairs.

Condition Certain 2014-2017 model year Cadillac CTS vehicles were built with HVAC actuators that had two internal wire junctions assembled with solder that contained lead above the allowable guidelines set by end of life vehicle recyclability laws in Europe and Korea.
Correction Remove the non-compliant actuators and replace with compliant stock.

Service Procedure

EQUIPPED WITH HVAC System-Air Conditioning, Front & Rear Electronic Controls (RPO CJ4) & Engine Control-Stop/Start System (RPO KL9)

  1. Remove the air inlet valve actuator. Refer to Air Inlet Valve Actuator Replacement (Fresh Air) in SI.
  2. Remove and replace the mode valve actuator. Refer to Mode Valve Actuator Replacement (CJ4) in SI.
  3. Remove and replace the console mode valve actuator. Refer to Mode Valve Actuator Replacement – Console (Left Side) in SI.
  4. Remove and replace the auxiliary temperature valve actuator. Refer to Temperature Valve Actuator Replacement (CJ4) in SI.
  5. Remove and replace the left side temperature valve actuator. Refer to Temperature Valve Actuator Replacement – Left Side (CJ4) in SI.
  6. Remove and replace the right side temperature valve actuator. Refer to Temperature Valve Actuator Replacement – Right Side in SI.
  7. Recalibrate the actuators following the procedure below.

Note: When replacing an HVAC actuator it will be necessary to allow the HVAC control module to perform a recalibration process. When installing an HVAC actuator be sure to perform one of the following.

 

Preferred Method (with Scan Tool)

Note: Do not adjust any controls on the HVAC control module while the HVAC control module is self-calibrating. If interrupted, improper HVAC performance will result.

  1. Clear all DTC’s.
  2. Ignition off.
  3. Install the HVAC actuators.
  4. Connect all previously disconnected components.
  5. Start the vehicle.
  6. With the scan tool, initiate the HVAC Actuators Relearn feature of the HVAC Control Module located in Configuration/Reset Functions. Follow the HVAC Actuators Learn process.
  7. Operate system and verify that no DTCs have set as current DTCs.
  8. If DTC B101E 4B is set after attempting the actuator recalibration procedure, perform the following:
  9. Verify which actuator does not have a scan tool learn status parameter status of complete. These actuator learn status are located under Data List, HVAC Door Position Data.
    1. Verify the unlearned actuator is physically rotating – A common cause of DTC B101E 4B is an actuator that is electrically OK but fails to physically rotate (e.g. stripped gears).
    2. If the unlearned actuator is not physically rotating, replace the actuator, otherwise replace the HVAC control module.

 

Alternate Method (without Scan Tool)

Note: Do not adjust any controls on the HVAC control module while the HVAC control module is self-calibrating. If interrupted, improper HVAC performance will result.

  1. Clear all DTC’s.
  2. Ignition off.
  3. Install the HVAC actuators.
  4. Connect all previously disconnected components.
  5. Remove the HVAC control module fuse for a minimum of 10 seconds.
  6. Install the HVAC control module fuse.
  7. Start the vehicle.
  8. Wait 40 seconds for the HVAC module to self calibrate.

Dealer Responsibility

Dealers must take the steps necessary to ensure that the service update correction has been made to all involved vehicles in dealer inventory before selling or dealer-trading the vehicle, but no later than September 30, 2017.

All new, used, GM Certified Used, courtesy transportation vehicles, dealer shuttle vehicles, etc. in dealers’ possession and subject to this bulletin must be held and inspected/repaired per the service procedure of this bulletin before customers take possession of these vehicles. Involved vehicles must be held and not delivered to customers, dealer-traded, released to auction, used for demonstration, or any other purpose.

All GM Certified Used vehicles currently in the dealers’ inventory within the Certified Pre-Owned Inventory System (CPOIS) will be de-certified and must be held and remedied per the service procedure in this bulletin. Upon submitting an accepted/paid warranty transaction in the Global Warranty Management (GWM) system, the vehicle can be re-certified for sale within the CPOIS system, or once again be used in the CTP program.
