Hi. A while ago I asked help with my wife's Fiat Qubo (Drive from wheelchair Sirus conversion which I have imported to South africa in 2019). The gearbox was giving us problems and to my surprise I learned from members on this forum that the problems with the dualogic gearbox was probably due to a faulty brake light switch, which I replaced with a new one. The problem seemed to have been solved, but two days ago, the gearbox played up again. I took the car back to the dealer who replaced the brake light switch but they found it to be perfectly in orde. The scan report however indicated a number of errors. The technician used a scan of a 2008 Fiat Fiorino 1.3 16 V M JET Dynamic and found a number of errors. He is not sure what to do about it because the gearboxes on the 2010 Fiat Qubo I am driving and the 2008 Fiat Fiorino is apparently not the same. I must admit that I do not have a clue about this things!!
The codes are as follows:
1. ECU = ABS, DTC code C1221-86, ECM bus signal invalid.
2. ECU = BCM, DTC code B1027-13, External temperature sensor - circuit open
3. ECU = TCM, DTC code, P1770-81, Accelerator pedal, invalid serial data received
4. ECU = TCM, DTC code, P0710-81, Fault on CAN message related to temperature signal - invalid serial data received
5. ECU = TCM, DTC code, P1819-8F, CAN message fault related to torque, Erratic
6. ECU = TCM, DTC code, P0856-81, Braking System Control Module (BCM) gearshift, invalid serial data received
7. ECU = TCM, DTC code, P1772-1D, Gear lever sensors, Circuit current out of range
8. ECU = TCM, DTC code, P1235-62, Accelerator pedal potentiometer congruence-Signal compare failure
I guess what I want to know is (a) how serious the problems are and (b) if it can be fixed?
This car is my wife's legs - without the car she is stuck in the house, I cannot go to a dealer in SA and buy another one, so this car must work!
Any advice?
