Measurement values, control unit connections PSG 16: Remember:: Notes

• Pay attention to the measurement requirements, use common sense when judging the measurement result.
• The measurement values which are given are with the ignition ON unless otherwise stated.
• Check first that there is a voltage supply to the control module and that it is grounded.
• Then check all sensor inputs and signals from other systems.
• Lastly check the outputs of the control module. Remember that the output values do not say anything about the functioning of the related actuator.
• If any measurement value is incorrect, use the wiring diagram to determine which cables, connectors or components should also be checked.
• The given measurement values are as measured with a calibrated Fluke 88/97.
• The measurement values %(+) and ms(+) show respectively the pulse ratio and the pulse length. A test instrument with pulse ratio and pulse width measurement must be used. The plus sign (+) denotes a positive trigger pulse, TRIG+.
