Test Readings, Control Module Connections



Test Readings, Control Module Connections







Scope
Values and directions for measuring the voltage levels in the control module are given 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 test readings do not indicate whether or not the actuator is in working order.
- If any reading is not OK, consult the wiring diagram to trace the leads, connectors or components which should be checked more thoroughly.
- The specified test readings refer to those obtained with a calibrated Fluke 88/97.
- Test values %(+) and ms(+) indicate the pulse ratio and pulse rate of the signal respectively. A scan tool for measuring pulse ratio and pulse width respectively must be used. The (+) indicates positive trigger pulse, TRIG+.
