P0614ECM/TCM Incompatible
- Generic OBD-II code · Powertrain
- Turns on the check-engine light
- Matters for the ITP
- Can trigger limp mode
- How the car detects it
- P0614 means the software or calibration variant of the engine module does not match the fitted transmission module or transmission type, or the transmission module is not registered. CARB allows modules with several calibration variants (for example manual and automatic) to share one calibration ID only if a wrong variant turns on the lamp – exactly this check. GM's V6 engines (Saab 9-5 2010) run it continuously with ignition on and light the lamp in the first trip, also for incomplete programming; Saab's Bosch ME9 sets it when a wrong variant is programmed, without any other system reaction. Typical cases are a used module from a car with a different gearbox or a software update applied to only one of the two modules.
