Condition/Concern
As part of our ongoing quality improvement process, effective November 1st, 2010 the K114B Hybrid Powertrain
Control Module 2, also known as the HPCM 2 part numbers 22994053 and 22985723 are being placed on restriction
through GM TAC (Technical Assistance Center).
Note: If the part is being ordered for a non warrantable concern (i.e. collision, theft, fire, etc.) proceed directly to step
6 below (Valid VIN and proof of ownership required).

Recommendation/Instructions
1. Please have a certified Volt technician follow the procedures below prior to contacting TAC.
Important: Do NOT erase DTCs in any of the modules (especially on intermittent concerns) and do NOT attempt to
reprogram software!
2. Check and record all diagnostic codes in all modules on the vehicle.
3. Be sure to record what module the DTC came from and any symptom codes associated with the DTCs (see
latest version of bulletin 10-07-30-002A for snapshot information).
4. Please save the DTC captured data for later use.
5. Once the above information has been obtained, please review all P.I and TSB information and all available S.I.
diagnostics.
6. If diagnostics lead to HPCM 2 replacement, contact TAC @ 877-446-8227 (U.S.) or in Canada 1-800-263-7740
(English) or 1-800-263-7960 (French) to review case details. Please have as much stored DTC and snapshot
information as possible prior to contacting TAC.
7. After reviewing the diagnosis, if component replacement is needed, TAC will arrange for ordering of the new
component and request that it be shipped overnight.
Note:
After reviewing the diagnosis, if component replacement is needed, GM TAC will arrange for ordering of the
part(s). When this occurs, record the last 9 digits of the TAC case # to be used by the parts department (in
conjunction with the part #) as the CONTROL NUMBER to track shipment of the part. It is not necessary to call
TAC for part tracking information.
