Technical FIAT UNO OBD socket
On left hand steered cars its on the co-Drivers side at he lower part of the A-Pilar.
It´s only a three port plug.
The engine control unit Bosch have a diagnostic connector, which outputs an error code on impulses.
Triple socket hangs near the control unit in the front passenger footwell. You can makeshift Reconnect an LED. The LED should be with a series resistor of 1k ohms with 12V and the white and red wires of the diagnosis connector connected. If the LED lights with the engine running, something is in the fault memory. (For models from 1992 and partly from mid-1992 is a failure of the control unit in the dashboard by lighting the lamp injection system diagnostics appear).
Bridged one, with the engine running at the diagnostic connector, for 5 seconds looking-red with black, the output of the error memory is initiated. The LED then flashes 4 x * by a total output a 4-digit code. Between blink intervals is a pause of 2 seconds.
Key:
0000
start / end error memory read
1111
Unknown defect of the controller
1232
throttle position (motor faulty, defective butterflyvalvesensor)
2121
No signal from butterflyvalvesensor, throttle switch (short circuit, wiring, etc.)
2122
No speed signal (Hall sensor, ignition module, etc.). This error is in the Digiplex ignition control.
2212
No signal from butterflyvalvesensor (short circuit, wiring, etc.)
2312
No signal temperature sensor coolant
2322
No signal from the temperature sensor injection < br> 2341
lambda control; exceeded limits, defective oxygen sensor, secondary air, injection or ignition
2342
No signal from the oxygen sensor 2343

No errors in the error memory
error memory of the Monojetronic delete:
diagnostic connector for min. 15 seconds. when the ignition bridge (black with white-red).
