Points to remember

  1. Observe the test conditions, use your common sense when judging the readings obtained.
  2. The specified values are with the ignition in position ON unless stated otherwise.
  3. First check that the control module is supplied with current and grounded.
  4. Then check all sensor inputs and signals from other systems.
  5. Finally, check the control module inputs. Remember that the test readings do not indicate whether or not the actuator is in working order.
  6. If any reading is not OK, consult the wiring diagram to trace the leads, connectors or components which ought to be checked more thoroughly.
  7. The specified test readings refer to those obtained with a calibrated Fluke 88/97.
  8. Test readings %(+) and ms(+) indicate the signal's pulse ratio and pulse duration. A test instrument capable of measuring pulse ratio and pulse width must be used. The sign denotes a positive trigger pulse, TRIG+.
