1. Disconnect a socket and at the included ignition check up presence of pressure from the battery on a conclusion 4. If pressure is not present, check up a chain from the main relay of injection to the gauge. |
2. Attach a socket and on the working engine check up pressure presence between conclusions 1 and 3, having connected probeы the voltmeter to a back part of conclusions. Pressure should from 1,0 to 1,5 V.Pri reduction or increase of turns of the engine pressure on these conclusions should fluctuate. |
3. If pressure does not correspond specified check up integrity of wires of the gauge. |
4. Before gauge replacement check up it in car-care centre. |
