CPEL node: timeout in CAN communication
Possible cause
• CPEL is missing power • CPEL node is broken • Defect connectors on CUV for Auxilliary CAN-bus (pin C35 or pin C36). • Defect wiring for Auxilliary CAN-bus, open circuit on CAN-high (pin C35) or CAN-low (pin C36). • Ignition signal (pin C24) on CUV is short circuit to supply.
