Cruise Control Module: Testing and Inspection
Scope
Test readings and directions for measuring signals and levels on the cruise control module are given in the following pages.
Remember:
-
Note the test conditions and use common sense when assessing the test result.
-
The test readings presented 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 reading does not tell us whether 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.
-
The test readings % (+) and ms (+) indicate the pulse ratio and pulse duration of the signal. A test instrument for measuring pulse ratio and pulse
duration must be used. The (+) sign indicates a positive trigger pulse, TRIG+.
The pins are identified by both a number and a letter. Note that Pin I does not exist.
