- 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+ .
