The PL1 control software is used for activation of park lock solenoid 1 (DirectDrive transmission).
Location: Included in control unit for gear shifting (DirectDrive transmission)
The control softwares PL1, PL2, PL3 and PL4 monitor and control engagement and disengagement of the park lock. The following information is processed and implemented:
– Come-home connector position
– Reverse drive lever position
– Engine speed
– Vehicle speed
– Status of park lock solenoid 1 (DirectDrive transmission)
– Status of park lock solenoid 2 (DirectDrive transmission)
In come-home mode, the following signals are also required:
Position of clutch pedal potentiometer Supply voltage (ELX)

Reaction of Control Software: Limited or no function of the vehicle.
PL1 000630.02 (PL1 630.02)— Control Software, Internal Error
The diagnostic trouble code is generated if the control software detects that the internal memory contains an incorrect entry. Reprogram the control software.
PL1 000630.13 (PL1 630.13)— Driver Not Calibrated
The diagnostic trouble code is generated if the control software detects that the internal memory contains an incorrect entry. Reprogram the control software.
PL1 000639.12 (PL1 639.12)— Vehicle CAN Bus (500 kBd), High Error Rate
The diagnostic trouble code is generated if the control software receives too many incorrect CAN Bus messages or if it detects a general problem in the connection to the vehicle CAN Bus (500 kBd).
Reaction of Control Software: Limited or no function of the control software.
PL1 000639.14 (PL1 639.14)— Vehicle CAN Bus (500 kBd), Very High Error Rate
The diagnostic trouble code is generated if the control software receives too many incorrect CAN Bus messages or if it detects a general problem in the connection to the vehicle CAN Bus (500 kBd).
Reaction of Control Software: Limited or no function of the control software.
PL1 001231.12 (PL1 1231.12)— Drive Train CAN Bus (1000 kBd), High Error Rate
Unable to process all CAN Bus messages received. This is possibly caused by a CAN Bus overload or an internal control unit fault.
Reaction of the control software: Limited or no function of the control software.
PL1 001231.14 (PL1 1231.14)— Drive Train CAN Bus (1000 kBd), High Error Rate
Too many incorrect CAN Bus messages received. This indicates a general problem at the connection to the Drive Train CAN Bus (1000 kBd).
Reaction of the control software: Limited or no function of the control software.
PL1 002071.09 (PL1 2071.09)— Incorrect CAN Bus Message, Information from CCU Control Software
Data transfer problem between the CCU control software and PL1 control software. This indicates a problem in the CAN Bus or in the transmitting control software.
Reaction of the control software: Limited or no function of the control software.
PL1 002168.09 (PL1 2168.09)— Incorrect CAN Bus Message, Information from PL3 Control Software
The diagnostic trouble code is generated if a data transfer problem occurs between the PL1 control software and the PL3 control software. Reception of messages sent on the CAN Bus by the PL3 control software is intermittent or non-existent. This indicates an open circuit in the CAN Bus, a short circuit or faulty CAN Bus terminators.
Reaction of Control Software: Limited or no function of the control software.
PL1 002169.09 (PL1 2169.09)— Incorrect CAN Bus Message, Information from PL4 Control Software
The diagnostic trouble code is generated if a data transfer problem occurs between the PL1 control software and the PL4 control software. Reception of messages sent on the CAN Bus by the PL4 control software is intermittent or non-existent. This indicates an open circuit in the CAN Bus, a short circuit or faulty CAN Bus terminators.
Reaction of Control Software: Limited or no function of the control software.
