Electrical system
Error cause
•
The VCU does not receive the signal from the ABS control unit.
Troubleshooting
•
Check the continuity of the cable between PIN K2 VCU - PIN 6 ABS control unit and between
PIN J2 VCU - PIN 5 ABS control unit. The error is automatically memorised when the com-
munication between the two control units is restored. To exit the diagnosis status and allow
the VCU to resume operation in normal conditions, it is however necessary to switch from
«OFF» to «ON».
Error Frame Counter motor control unit C1306
Error cause
•
Failed synchronisation between VCU and motor control unit on data packets sent/received
(for each packet sent, the VCU increases by 1 its internal counter, and when it reaches 15
it resets itself).
Troubleshooting
•
Possible contact or interruption of the cable that must be checked: Check the continuity of
the cable between PIN K2 VCU - PIN 66 VEHICLE motor control unit and between PIN J2
VCU - PIN 80 VEHICLE motor control unit. Check also the insulation of the two cables
between themselves, from supply and ground.
Error Frame Counter ABS C1307
Error cause
•
Failed synchronisation between VCU and ABS control unit on data packets sent/received
(for each packet sent, the VCU increases by 1 its internal counter, and when it reaches 15
it resets itself).
Troubleshooting
•
Possible contact or interruption of the cable that must be checked: Check the continuity of
the cable between PIN K2 VCU - PIN 6 ABS control unit and between PIN J2 VCU - PIN 5
ABS control unit. Check also the insulation of the two cables between themselves, from
supply and ground.
Error Frame Counter instrument panel C1308
Error cause
•
Failed synchronisation between VCU and instrument panel on data packets sent/received
(for each packet sent, the VCU increases by 1 its internal counter, and when it reaches 15
it resets itself).
Troubleshooting
•
Possible contact or interruption of the cable that must be checked: Check the continuity of
the cable between the PIN K2 VCU - PIN 27 instrument panel (black connector) and PIN J2
