Measure values, control module connections, SID




Scope

Below the headings, values and directions can be found for measuring voltage levels of the SID unit.

Keep in mind


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

• The values presented are with ignition ON if nothing else is stated.

• 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)
