Scope

Values and directions for measuring signals and levels in DICE can be found on the following pages.

Keep in mind


• Note the measuring conditions, use common sense when considering the measurement results.

• The values given apply with the ignition key in the ON position unless otherwise indicated.

• First check that the control module is supplied with power and that it is grounded.

• Then check all the sensor inputs and signals from other systems.

• Finally, check the control module outputs. Remember that the measured values will not indicate if the switch device is functional.

• If any measured value is incorrect, use the wiring diagram to diagnose which leads, connections or components that should be checked further.

• Given values refer to calibrated Fluke 88/97.

• The measured values %(+) and ms(+) show the pulse ratio and pulse duration of the signal. A test instrument with pulse ratio and pulse duration measuring capacity must be used. The sign (+) indicates positive trigger pulse, TRIG+.







> = greater than

< = less than

» = approximately equal to

∼ = alternating current

(LP: LOGIC PROBE P = select pulse; p = visible pulses)

For other measured values and control module connections, refer to group 03, DICE
