Diagnostic Trouble Code 3-1-1
Diagnostic trouble code (DTC) 3-1-1Too many input signals simultaneously
Diagnostic trouble code (DTC) 3-1-1 is obtained when the control module receives more than one input signal within 8 milliseconds. This means in practice that it is impossible to have manoeuvered two switches at the same time. However it can occur if there is a contact malfunction in a contact or switch, or if two cables made temporary contact.
Start by activating the switch or contact that caused 3-1-1 to blink. If 3-1-1 blinks again: check wires and switches in accordance with the trouble code that should have appeared.
