Scope
On the following pages, there are values and directions for measuring signals and levels of the control module.
Keep in mind
- Note the test conditions, and use common sense when assessing the test results.
- The specified readings are with the ignition in position ON unless otherwise stated.
- First, check that the control module is supplied with current and is grounded.
- Then check all sensor inputs and signals from other systems.
- Finally, check the control module outputs. Remember that the test readings do not indicate whether the actuator is working.
- If any reading is not correct, consult the wiring diagram to trace the leads, connectors or components that should be checked more thoroughly.
- The test readings given apply to a calibrated Fluke 88/97.
- The test readings show the signal's pulse ratio and pulse width. A test instrument with pulse ratio and pulse width measurement must be used. The (+) sign indicates a positive trigger pulse, TRIG+.
= greater than; <= less than; = alternating current (LP: LOGIC PROBE P = select pulse; p = visible pulse)
