C1201D
Diagnostic information CAN
Communication with control unit not possible
NOTE: Internal function test completed.
Diagnostic conditions
The PAS control unit initially tests internal function sequences after wakeup. If they are OK, all diagnosable outputs are then tested and
any faults are stored.
Wakeup of the control unit by:
Eventcontrolled CAN message
Key contact (terminal S)
Ignition ON
Possible fault causes
No power supply of the control unit
Incorrect coding of the control unit
Short circuit or open circuit in the CAN network
Control unit faulty (in most cases, faulty coding is the cause and not the control unit)
Fault effects
Communication no longer possible via the CAN bus
The control unit is no longer addressable for all other control units
