And Function
Both "babbling control modules" and "disruptive control modules" can have intermittent faults that are not necessarily apparent when the car is in the
workshop. In some cases, "disruptive control modules" do not set diagnostic trouble codes (DTCs). The following method should therefore be used to
fault-trace:
-
Measure the voltage between the green and white CAN cables in the relevant CAN network. The average voltage value is normally 0.5 V
-
If a control module is "disruptive", the voltage is usually above 0.7 V
-
If this is the case, cut the power to the control modules in accordance with the method described about to find the fault cause
-
Verify that the correct control module was faulty by repeating the fault, with and without the faulty control module connected in the CAN network.
Note! Following faults with "babbling" or "disruptive" control modules, some control modules may remain in "Limp-home mode" even after
the ignition key has been removed and inserted in the ignition switch again. To remedy this, disconnect and reconnect the battery negative
terminal to restore the control modules to normal function.
