Description:
Modern diagnostics systems can be a blessing or a curse, depending on your level of understanding. This book helps you harness the power of the diagnostics inside the ECU to improve the ability to find and make the right repair the first time. This book shows that by using commonly available electronic tools, the consumer has the power to access a wealth of information about his or her vehicle. It also helps those who are looking to improve performance do so without compromise to the environment or enforcement agencies. Whether you want to repair the vehicle yourself or simply want to possess an understanding of how these systems work while dealing with service professionals, this is the guide you need.

Backgrounds & Origins
The malfunction indicator lamp (MIL), also commonly referred to as the check engine light, is tested at every startup to make sure it is working. After that, it is used to alert the driver to a condition that needs to be addressed to keep the engine running properly.
Uses of OBD
Some auto-parts stores allow you to connect a scan tool to your vehicle for free while you’re there in hopes that you will also purchase the parts necessary to repair the vehicle on the same visit. Of course, they also sell several versions of these tools.
CAN & Other Networks
The introduction of SAE J1962 brought a common connection point to all vehicles along with common power and ground locations within that connector. Early data pins varied, but eventually became standardized with the introduction of CAN.
I’ve been preaching it for years: proper calibration requires a fair amount of steady-state measurement on a load-bearing dyno to build the base maps. Thus, a Mustang dynamometer with an eddy current absorber lets the user hold the engine at a constant RPM while the driver controls engine load with the accelerator pedal to get the necessary measurements.
Basic Engine Controls
Manufacturers have gone from single knock sensors to the most sensitive applications having one almost touching each individual cylinder to better capture the noise at the source. Raw knock-sensor signals are filtered for timing relative to those cylinders’ combustion events and the frequency of the expected noise.
Fault Code Fundamentals
If a wheel-speed sensor is unplugged or failing, it should show up as a C code on the scan tool. This may have a direct impact on powertrain behavior because so many engine and transmission controls are tied to vehicle speed inputs.
Generic SAE Fault Codes
Looking at this data shows both banks of this engine maxed out with 2-percent positive fuel trims and still more positive adjustment happening in the short-term trims. This is normal for a case where the P0171/P0174 faults have been set for “Bank 1/Bank 2 Lean” as the ECU tries to correct the error.
