| General notes on the injection system |
| The engine control unit is equipped with a self-diagnosis system. Before repairs as well as for fault finding first interrogate the fault memory. Also check the vacuum hoses and connections (unmetered air). |
| A minimum voltage of 11.5 V is required for perfect functioning of the electrical components. |
| If after fault finding, repair or inspection of components the engine starts briefly and then stops, it is possible that the immobiliser blocks the engine control unit. Then interrogate the fault memory and if necessary adapt the control unit. |
| Certain inspections may cause the control unit to detect and store a fault. It is therefore necessary to interrogate the fault memory after having completed all inspections and repairs, and if necessary delete → Chapter. |
