DIS2 node: timeout in CAN communication.
شرح
The DTC is set active if the CAN-message GeneralInfoDISProp has been absent for 300 ms on the CAN bus. The DTC is set to inactive if the CAN-message GeneralInfoDISProp is received. The DTC is not set in the following cases: • Ignition is turned off • First 2 seconds after ignition on • System voltage is below 22 volt • System voltage is above 30 volt
علت
• Faulty DIS2 unit • DIS2 unit disconnected from the evironment sensor CAN bus If all connected ECUs on the sensor CAN-bus present timeout error codes the cause might be: • Defect wiring : - Short circuit between CAN-high and supply voltage. - Short circuit between CAN-low and ground. • Defect ECU unit(s) on the CAN bus.
rom the CAN bus and check if the remaining ECU timeout error codes disappear.
