Vehicle manufacturers have helped you locate a driveability problem by designing Electronic Control Unit s with trouble-code generating capabilities. But, the ECUs aren’t perfect because they don’t cover everything (most glitches and intermittents). On-board diagnostic systems are engineered with fairly wide set limits for sensors, actuat ors, connectors and terminals.

When a component exceeds its limit consistently, a trouble code is generated. But to keep warranty costs in line, tolerances aren’t set to catch all transients, even though they can cause some of your worst driveability problems. Therefore, repair technicians are finding more and more uses for a Digital Storage Oscilloscope (DSO) and a Digital Multimeter (DMM) thesedays. A DSO can capture a live “signature” of a circuit and store it for later analysis or comparison against Known-good waveforms - an invaluable resource for detecting marginal components. A GMM (Graphing Multimeter) gives you advanced multimeter capabilities coupled with the visual power of trend graphing and waveform display. This Met er a combination DSO and GMM represents the most powerful and versat ile tool available for troubleshooting automotive electronics since we can track down elusive no-code driveability problems.

1.1 COMPARING SCAN TOOLS, DSOs AND DMMs All of these tools have unique capabilities, and today’s vehicles demand that automotive technicians are able to use all three tools to correctly diagnose various driveability problems. DSOs alone cannot replace DMMs or scan tools. By the same token, DMMs or scan tools cannot replace DSOs. For example, when anti-lock brakes on your car are sometimes erratic, you might firstly try a road test to notice that the ABS light does not come on. When you get back to the shop, you plug in your scan tool and find no trouble codes.

Because you still have your DMM, you follow the manufacturer’s instructions and you look at the output voltage from each of the wheel speed sensors. They all appear to be in tolerance, and the manufacturer’s fault tree recommends you to replace the ABS computer.

Unfortunat ely, the ABS computer on this vehicle is embedded in the mast er cylinder, so you must replace everything. The worst thing is the problem still exists even after you complete all of the work.
