Test readings, driver door module, (702D)

Scope



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+.

Note

All units on the I and P-buses send signals.
