ECM And PCM Calibration Numbers
Finding out if the vehicle has the latest version or calibration on a module is a required step.
ECM Damage
Engineers have devised two strategies that can be called the “immune system” for the electrical system.
ECM/PCM Communication Issues (VIDEO)
Before you swap out a module that won’t communicate, do a few simple inspections. Sponsored by The Group Training Academy.
ECM No Communication Issues
The source of the problem could be software, electrical or mechanical.
VIDEO: Power Steering ECM Technology
Andrew Markel discusses power steering systems, and how it uses sensors and the ECM to add steering assist during certain road conditions.
VIDEO: ECM Alternator Regulation; No More Full Field Testing
Andrew Markel explains how modern alternators are designed to have their loads regulated by the ECM, eliminating the need for full field testing.
Outsmarting The Smart Cars: ECM Replacement
The ECM’s (engine control computer) function is to control emissions, monitor and regulate engine functions as well as optimize engine performance and fuel consumption.
Fuel Pressure Diagnostic Service
Use a scan tool that can look at special direct fuel injection parameters and perform bidirectional tests.
Battery Charging and Diagnostics
Here are six tips to use when diagnosing a vehicle with a dead battery.
Fuel Pressure Diagnostics
Direct injection pressure is measured with sensors, and the signals are used to determine pump speed and/or volume.
