Test Reading, Telematics Unit (468)

Test Reading, Telematics Unit (468)

Scope










The following information include values and instructions for measuring signals and levels on the main instrument unit and its control module.

Remember
- Note the test conditions and use common sense when assessing the test result.
- 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 readings do not indicate whether the actuator is working.
- 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 values %(+) and ms(+) indicate the pulse ratio and pulse duration of the signal. A test instrument capable of giving pulse ratio and pulse duration readings should be used. The (+) symbol indicates a positive trigger pulse, TRIG+.
