Why might the help make yourSideWinder
ECM problem diagnosis more accurate?
“So, you have traced the problem down to the ECM motor - but which section
of the motor is the cause of the problem? If you send back the whole motor
(the module the winding section), you may be subject to chargebacksand
under warranty, or you may unnecessarily spend hundreds of the customer’s
dollars for out-of-warranty parts.”
Many unit manufacturers are starting to deny warranty claims for mis-diag-
nosed ECM motor problems. After years of giving Technicians grace after
sending back the complete motor, the unit makers realize that the tools now
exist for a Tech to properly determine when only a module - instead of the
complete motor - required replacement.
About is all that is needed to administer the two30 seconds SideWinder’s
main tests - and it may save you money, hours of work, and possibly the
embarrassment when an ECM motor claim is later denied.
Diagnosing which section of an ECM motor has a
problem has never been easier:
• First, perform your normal system diagnosis routines.
• If a failure in the ECM motor is indicated, disconnect power and remove
the two module screws.
• Unplug the 3-pin connector between the module and winding sections.
• Plug the 3-pin plug into the above connector.SideWinder’s
• Spin the shaft of the motor, and watch the Phase LED’s on the tool.
• Press the “Short Test” switch on the tool, while watching the LED’s.
That’s it! The LED’s have told you whether the winding sec-
tion has any faults. You can confidently use that information
to replace only those parts that really require replacement.
