The following information is provided to clearly explain Isuzuâs policy for control module (engine, transmission, antilock brake, instrument panel, body control, power interface, etc.) reprogramming. Control module calibrations are regularly updated for many reasons. These reasons may include, but are not limited to: model year change, software corrections, certification compliance, product improvement and specific application requirements. However, the mere existence of a newer control module calibration does not necessarily mean that warranty coverage exists or that the calibration must be installed. It is not our policy to update control modules, under warranty or after warranty, based solely on the availability of a newer calibration file. Below are our guidelines for reprogramming control modules.

The following table contains many possible causes for the following symptoms. -Hard Start/No Start -Rough, Misfire, Unstable or Incorrect Idle -Surges, Lack of Power, Hesitation, Lag or Stumble While some of these symptoms may lead to component replacement, the replacement should not be considered a completed repair. These types of symptoms have a high probability for a repeat repair since the true source of the failure is typically fuel contamination. In order to improve the overall repair and reduce the potential repeat failures, the procedure below is provided to assist in identifying the source of fuel contamination. Additionally, this bulletin will provide information to clarify the meaning of injector balancing rates and how to apply the values when trying to diagnose the Isuzu common rail fuel system.

Damage to fuel systems, including to both low and high pressure components, often results from fuel contamination. Operating a vehicle?s diesel engine on fuels and additives that do not meet the vehicle manufacturer?s specifications for lubrication and cooling, or that have improper anti-corrosion properties, can cause drivability problems as well as component damage or even failure. Due to the tight tolerances on modern diesel engines, contaminants such as water can dilute the lubricating properties of diesel fuel and cause engine damage. For instance, water can lead to acid forming in the fuel system, which can be extremely caustic and harmful to the engine. Contamination of high pressure fuel system components may cause symptoms including, but not limited to, the following:
