- 12659039
- Notes
- Parts reference: Historical physical Engine Control Module service part 12659039, ECU family E82, for 2016 Cadillac CTS equipped with the 3.6L LGX engine only. GM PIP5306B (April 2016), page 1 identifies this named model, year, engine and restricted ECM part number. The bulletin described a historical PQC engineering-feedback parts restriction after SI diagnostics led to ECM replacement; this process is not verified as current policy and no restriction ending or current ordering approval is established. Questionnaire items are diagnostic prompts, not additional fitment or eligibility requirements. No mandatory specific symptom or DTC gate is specified. Quantity, VIN range, body, trim, drivetrain, transmission, build, emissions and equipment allocation remain unverified. Match exact VIN, original module and current OEM replacement selection before ordering. Current ordering, supersession, availability, warranty eligibility, interchange, programming, key, cloning and repair capability remain unverified. No other engine, 2017 or other model year application is included. CTS-V, coupe, wagon, CT6-V and CT6 Plug-In remain outside this qualified scope. Hardware-label, serial and calibration identifiers are separate from this physical service part number.

- Parts reference: Historical physical Engine Control Module service part 12679078, ECU family E82, for 2016 Cadillac CTS equipped with the 3.6L LGX engine only. GM PIP5306F (June 5, 2017), page 1 specifies this exact model, year and engine; the VIN-from, VIN-to and transmission columns each state ALL within that scope. The bulletin ended the historical PQC parts restriction and stated that the ECM could then be ordered through the normal parts catalog; this is not verification of current ordering, availability or VIN-specific selection. PIP5306F superseded PIP5306E to end that restriction. Unspecified successors are not an established supersession or interchange chain, and no relationship to another part number is established here. No mandatory symptom or DTC gate is specified. Quantity, body, trim, drivetrain, build, emissions and equipment allocation remain unverified. Match the exact VIN, original module and current OEM replacement selection before ordering. Current ordering, supersession, warranty eligibility, interchange, programming, key, cloning and repair capability remain unverified. No other engine or model year application is included. Hardware-label, serial and calibration identifiers are separate from this physical service part number.
Reference information for 2016. Coverage can vary by year and equipment. Confirm the VIN and full part number before ordering a replacement.
