connector; if NOT OK restore and if OK check the general operation of the Marelli control
unit and of the LH light switch; in case of anomalies, replace the part concerned.
NOTE
THIS ERROR DISABLES THE CRUISE CONTROL.
DIAGNOSTIC TOOL: LOGIC ERRORS
U0121 "ABSENT NODE" ABS control unit
Functional diagnosis:
Missing signal / signal not plausible/ config error
Error cause:
•
Missing communication of the ABS control unit to the CAN line
This error is indicated by lighting up in a fixed manner the MI warning light.
Troubleshooting:
•
Disconnect the ABS control unit connector and check that there is no dirty, oxidised or dam-
aged PIN; if not ok, restore; if ok, check the continuity between the ABS control unit PIN 2
and PIN 11 and PIN 66 and PIN 80 of the VEHICLE connector of the marelli control unit; if
not ok, restore; if ok, check the continuity between the ABS control unit PIN 2 and PIN 11
and PIN 32 and PIN 33 of the instrument panel; if not ok, restore; if ok, check the continuity
between the ABS control unit PIN 2 and PIN 11 and PIN 3 and PIN 4 of the LH light switch;
if not ok restore, if ok check that there is no continuity between the two cables of the CAN
line (L and H); if not ok restore, if ok check that there is no continuity between vehicle ground
and the battery positive; If not ok, restore; if ok, replace the ABS control unit.
NOTE
THE PRESENCE OF THIS ERROR DETERMINE THE DEACTIVATION OF THE TRACTION CON-
TROL AND THE CRUISE CONTROL.
U0125 CAN line sensor box diagnosis
Functional diagnosis:
•
No signal/Configuration error
Error cause:
•
If there is missing signal, no signal arrives from the inertial platform (Sensor Box). In case
of configuration error, some devices are present (e.g. Sensor Box) that were not foreseen
in the vehicle configuration stored in the control unit.
This error is indicated by lighting up in a fixed manner the general warning light.
Troubleshooting:
•
Missing signal - Perform the check procedure for PIN 2 and PIN 3 of the inertial platform
(Sensor box) connector, for PIN B2 and PIN B3 of the vehicle-engine connector, for pin 66
and 80 of the Marelli control unit VEHICLE connector: if NOT OK restore, if OK with key
OFF, disconnect: a) the ABS control unit connector, b) the connector of the inertial platform
(Sensor box) and check the continuity between PIN 3 of the inertial platform (Sensor box)
