The following pages contain directions and readings for testing signals and levels of the control module.
Remember
^
Observe the test criteria. Use common sense when assessing the test results.
^
Check first that the control module is receiving power and is grounded.
^
Then check all sensor inputs and signals from other systems.
^
Finally, check the control module outputs. Remember that the test readings are not a confirmation of whether the actuator is in working order.
^
If a test reading is incorrect, use the wiring diagram to locate the leads, connectors or components that need to be checked further.
^
Specified readings are for a calibrated Fluke 88/97.
^
Test readings % (+) and ms (+) indicate the signal pulse ratio and pulse width respectively. A scan tool with pulse ratio and pulse width
measurement must be used. The sign indicates positive trigger pulse, TRIG+.
J1
NOTE: All units on the I and P-buses send signals.
