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 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(+) shows the pulse of the signal respective pulse length. Test instrument with pulse quotient respective pulse width measuring capacity must be used. The sign (+) indicates positive trigger pulse, TRIG+.







>= greater than; <= less than; ~= alternating current

A pin without further comments does not have a pin connection. (LP: LOGIC PROBE P= select pulse; p= visible pulses)
