Test Description

WARNING: This page is about a different car, the 2002 Oldsmobile Intrigue and 2002 Oldsmobile Aurora. However, it is still accessible from the selected car via links, so may be relevant.

The numbers below refer to the step number in the diagnostic procedures.

3

Normally, ignition feed voltage should be present on the control circuit with PCM disconnected and ignition on.

4

This step checks for a shorted component or a short to B+ on the control circuit. Either condition would result in a measured current of over 500 milliamperes. This step also checks for a component that is causing an open circuit while being operated, resulting in a measured current of 0 milliamperes.

5

This step checks for a short to voltage on the control circuit.

15

This vehicle is equipped with a PCM which utilizes an Electrically Erasable Programmable Read Only Memory (EEPROM). When PCM is being replaced, the new PCM must be programmed.
