A/C Oil Service: Achieving Balance
Not following the proper service procedures or compressor oil recommendations could be factors that contribute to premature compressor failure.
Ignition Diagnostics: Interpreting Secondary Waveforms
The secret to analyzing secondary ignition waveforms is understanding what is happening.
TPMS And Radio Waves: What You Can’t See Can Hold Up A Relearn
TPMS and keyless entry can be difficult to understand because these systems rely on transmitting, receiving and decoding radio waves.
Transmissions and Scan Tools
Even with codes and data stream information, you must be able to think like the transmission to find the correct diagnosis, which typically doesn’t involve replacing the entire transmission.
VIDEO: TPMS Sensor Protocols
Andrew Markel explains how a TPMS tool can help you program universal TPMS sensors.
Scan Tool Freeze Frames: Using Generic Data to Make a Specific Diagnosis
As part of OBDII, Mode$02 for the logging or freeze frame data was created. This diagnostic protocol saves data PIDs and information when a code is set.
VIDEO: 3 Reasons You Need a Scan Tool for Brake Repairs
Andrew Markel explains why you cannot efficiently or profitably complete certain brake repairs without a scan tool.
Using Fuel and Ignition Waveforms Together
Fuel injector and secondary ignition waveforms can show the condition of the fuel and ignition system, and combined they can give you new insights on misfires and if they are related to the fuel or ignition system.
