Examination
1. Turn the ignition key to the ON position.
2. If the arrows of the pointers do not move to the desired area of the pointer scale (empty tank, low pressure, cold engine), then check the fuse. If the fuse is good, then find the sensor of the corresponding indicator and connect the wire to the sensor to ground. If the arrow moves to the desired area of the pointer scale, then replace the sensor. Otherwise, connect to ground (in accordance with the scheme) output on the back of the pointer directly (jumper). If the arrow has moved, then the wiring from the pointer to the sensor is faulty. Otherwise, check the voltage at the second output of the pointer. If voltage is present, replace the pointer.
