Checks
Test turn indicator reset button function. When the button is pressed, there must be continuity between its two electric terminals (pin 3 and pin 1).
Check that there is a voltage of 5v on pin 1 of the turn indicator reset button arriving from dashboard pin 17.
Check the integrity of the electrical circuit and connections (short-circuits to ground, short-circuits to vdc, open circuits).
If none of the aforementioned tests identifies the problem, replace the dashboard.
Note
Check integrity of electric circuit - short-circuit to vdc = with dashboard on, using a voltmeter, a voltage is measured between the wire tested and ground.
Check integrity of electric circuit - short-circuit to ground = with the battery cables disconnected, using an ohmmeter, continuity is detected between the wire tested and ground.
Check integrity of electric circuit - open circuit = with the battery cables disconnected, using an ohmmeter, no continuity is detected between the two ends of the wire tested.
