Electrical system
•
The VCU does not receive communication from the instrument panel.
Troubleshooting
•
Check the continuity between VCU PIN K2 - instrument panel PIN 27 (black connector) and
between VCU PIN J2 - instrument panel PIN 26 (black connector). The error switches au-
tomatically to memorised status when communication between the two control units is
restored. In any case, to exit the diagnosis status and to allow the VCU to resume operating
in normal conditions, a switch from «OFF» to «ON» is required.
Failed CAN reception from ABS C1303
Error cause
•
The VCU does not receive communication from the ABS ECU.
Troubleshooting
•
Check continuity of the cable between VCU PIN K2 - ABS ECU PIN 6 and between VCU
PIN J2 - ABS ECU PIN 5. The error switches automatically to memorised status when com-
munication between the two control units is restored. In any case, to exit the diagnosis status
and to allow the VCU to resume operating in normal conditions, a switch from «OFF» to
«ON» is required.
Engine ECU C1306 Frame Counter error
Error cause
•
Failed synchronisation between VCU and engine ECU on the sent/received data packets
(for each packet sent the VCU increases its internal counter by 1, which resets at 15).
Troubleshooting
•
Probably contact or interruption of the cable harness that must be checked: check continuity
of the cable between VCU PIN K2 - engine ECU VEHICLE PIN 66 VEHICLE and between
VCU PIN J2 - engine ECU VEHICLE PIN 80. Also check the insulation of the two cables
from one another, from power and from ground.
ABS C1307 Frame Counter error
Error cause
•
Failed synchronisation between VCU and ABS ECU on the sent/received data packets (for
each packet sent the VCU increases its internal counter by 1, which resets at 15).
Troubleshooting
•
Probably contact or interruption of the cable harness that must be checked: check continuity
of the cable between VCU PIN K2 - ABS ECU PIN 6 and between VCU PIN J2 - ABS ECU
PIN 5. Also check the insulation of the two cables from one another, from power and from
ground.
