A system and method are disclosed for detecting tampering with the software, software parameters, and calibration data used by a vehicle controller. During authorized installation of controller memory images, a hash function is applied to selected regions of controller memory to obtain stored hash values. Then, periodically during operation of the vehicle, the hash function is applied to the then-current contents of the controller memory to obtain calculated hash values. If the stored hash values stored do not match the calculated hash values, a fault is logged for future retrieval by service personnel.
