Parking Assist Control Module: Testing and Inspection
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+.
