EWR high current output
Check he faulty unit, cable harness and connectors.
What you'll see
The driver will not be able to operate the electrical wheelchair ramp.
System reaction
Functionality of the electrical wheelchair ramp is missing or degraded. Error for the ramp will be shown in the ICL.
Diagnostic depth
High current on any of the outputs for connection to the body system on the control unit for the electrical wheelchair ramp has been detected. This information about the error is sent from the ramp to the MBS.
- Too high current or short circuit due to faulty component/output connections. - Problems with the control unit for the electrical wheelchair ramp or the node. - Possible overload of the ollowing output signals: - EWR active ( interface pin 4) - EWR extended ( interface pin 7) - Malfunction ( interface pin 5)* - Obstacle ( interface pin 13) * A fault can be detected since the malfunction output go low PERMANENTLY. All outputs have short circuit and overloaded protection which switches teh outputs off when needed.
