Engine Control Module: Service and Repair
Reprogramming the PCM
The Rodeo/Amigo allows reprogramming of the PCM without removing it from the vehicle. This provides a flexible and cost-effective method of
making changes in software calibrations.
The service programming system (SPS) will not allow incorrect software programming or incorrect calibration changes.
Refer to the latest Isuzu Technical Communication System information (See Technical Service Bulletins) for reprogramming or flashing procedures.
