Pinout Values and Diagnostic Parameters

Test Readings, Control Module Connections

Scope
Values and directions for measuring control module voltages can be found under the relevant heading.

Remember:
- Note the test conditions and use common sense when assessing the test result.
- The specified values are with the ignition ON unless otherwise stated.
- First check that the control module has a power supply and is grounded.
- Then check all sensor inputs and signals from other systems.
- Finally, check the control module outputs. Remember that the values do not indicate whether the actuator unit is working.
- If any reading is not OK, consult the wiring diagram to trace the leads, connectors or components which should be checked more thoroughly. " The test readings given apply to a calibrated Fluke 88/97.
- Test readings in %(+) and ms(+) show the pulse ratio and pulse duration of the signal. A test instrument capable of giving pulse ratio and pulse duration readings must be used. The (+) sign indicates a positive trigger pulse, TRIG+.
