Test Readings, Control Module Connections

Test Readings, Control Module Connections

Scope










The following pages contain readings and instructions for measuring signals and levels for SPA (Saab Parking Assistance).

Remember
- Note the test conditions and use common sense when assessing the test result.
- The specified readings are with the ignition ON unless stated otherwise.
- 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 these readings are not an indication that the actuator is in working order.
- If a reading is not OK, consult the wiring diagram to trace the leads, connectors or components which should be checked more thoroughly.
- Specified values concern a calibrated Fluke 88/97.
- Readings % (+) and ms (+) indicate the signal pulse ratio and pulse width respectively. A test instrument with pulse ratio and pulse width measurement must be used. The sign indicates a positive trigger pulse, TRIG+.
