DICE Control Module (628)
Test Readings, Control Module Connections
Scope
Values and directions for measuring the voltage levels in the control module are given under the relevant heading.
Points to remember
- Note the test conditions, use common sense when assessing the test results.
- The specified values are with the ignition ON unless otherwise stated.
- First check that the control module is supplied with current and is grounded.
- Then check all the sensor inputs and signals from other systems.
- Finally, check the control module outputs. Remember that the test values do not say anything about whether or not the actuator is functioning.
- If any reading is not OK, consult the wiring diagram to trace the leads, connectors or components which ought to 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+.
