Deteriorated or defective lambda sensors must be replaced with a new unit. De-
energize the Smart Lambda Sensor Cable before replacing the lambda sensor.

Startup Sequence
Sequence for the startup of the Smart Lambda Sensor Cable:
A Install LSU4.9 lambda sensor in the exhaust-gas routing (see chapter 3.3
B The connections of the CBS10x.1-2 Smart Lambda Sensor Cable can be
cabled in any order (see chapter 3.4 on page 22).

Technical Information
CAUTION
If the sensor heater is missing, it could lead to premature deterioration or
damage of the lambda sensor.
The lambda sensor must be supplied with current at all times as soon as it is
exposed to the exhaust gases of a combustion process.
If the CBS10x.1-2 cable is connected with a voltage supply, the required con
-
trolled sensor heater voltage is provided at the sensor connection.
NOTICE
Each lambda sensor is individually trimmed via a resistor in the plug of the
lambda sensor. For this reason, the plug of the lambda sensor may not be
removed.
TIP
Observe the general recommendations for installing and operating the Smart
Lambda Sensor Cable and the lambda sensor in chapter 3.1 on page 18!
TIP
