Info
For the measurement, the measurement points must be loaded with a 12V/21W bulb.
The value should not vary more than 1V from the battery voltage
"VBAT"
.
» If the measured value does not correspond to the specified value:
–
Check connector CU pin 3 .
–
Check the cable from connector CU pin 3 to the next node in the cable harness for an open circuit.
» If the measured value corresponds to the specified value:
–
Check the next possible cause:
Heating lambda sensor - value is not plausible (
p. 165)
Heating lambda sensor - value is not plausible
Condition
Th e diagnostic tool is disconnected.
