LambdaControl 1
Error 26.54
Acc. sensor F4
from Bus
Cause: Bus-Communication, Different number of accumulator sensor
Display 4 amber: illuminates
Information text: -
Emergency program: YES
Reset: Automatically after error correction
Cause of error: There is a wrong accumulator sensor No. set in the Lambda-Control 1
plus
. Are both CAN-bus plugs properly
pressed on to the CAN-bus cable?
Rectification: Call service technician – possible causes:
1. Test – is the correct accumulator sensor number set in the controller Lambda-Control 1
plus
? Is that the case, continue
with test 2.
2. Test – CAN-Bus cable: Are both CAN-bus plugs properly pressed on to the CAN-bus cable and is the cable properly
connected to the CAN bus terminal ( check the correct pin assignment)?
Experience shows that the controller is usually only defective, if faulty wiring or spurious actions damaged the applicable
input/output.
Controller function: Combustion without BSB.
Error 26.55: BSB F5(1 – 4) from BUS
LambdaControl 1
Error 26.55
BSB F5(1-4)
from Bus
Cause: Bus-Communication, Different number of accumulator sensor
Display 4 amber: illuminates

Emergency program: YES
Reset: Automatically after error correction
Cause of error: There is a wrong accumulator sensor No. set in the Lambda-Control 1
plus
. Are both CAN-bus plugs properly
pressed on to the CAN-bus cable?
Rectification: Call service technician – possible causes:
1. Test – is the correct accumulator sensor No. set in the Lambda-Control 1
plus
? Is that the case, continue with test 2.
The BSB F5(1-4) Sensor is interconnected with the accumulator sensor No.
2. Test – CAN-Bus cable: Are both CAN-bus plugs properly pressed on to the CAN-bus cable and is the cable properly
connected with the CAN bus terminal ( check the correct pin assignment)?
Experience shows that the controller is usually only defective, if faulty wiring or spurious actions damaged the applicable
input/output.
Controller function: Fuel calculation is not carried out.
