General Notes on Injection

General Notes On Injection

- The engine control module is equipped with self-diagnosis. Before performing repairs and troubleshooting the Diagnostic Trouble Code (DTC) memory of all control modules must be read. Also, the vacuum hoses and connections must be checked (for unmetered air).
- Fuel hoses in the engine compartment must be secured only with spring-type clips Electronic parts catalog "ETKA". The use of clamp or screw-type clips is not permitted.
- Disconnect the battery Ground strap only with the ignition switched off. If a coded radio is installed, obtain the radio code before disconnecting the battery.
- For trouble-free operation of electrical components, a voltage of at least 11.5 V is necessary.
- Do not use sealants containing silicone. Particles of silicone drawn into the engine, will not be burned in the engine and can damage the oxygen sensor.
- If the engine starts and runs only for a short period of time after performing fault finding, repairs or component tests and then stalls, it could be that the immobilizer is blocking the engine control module. The engine control module must then be adapted.
- During some checks, it is possible that the control module will detect and store a fault. Therefore, after completing all tests and repairs, read the Diagnostic Trouble Code (DTC) memory and erase it if necessary.
- Models with an airbag are equipped with a crash fuel shut-off system. It reduces the danger of a fire in a crash as the fuel pump is switched off by the fuel pump relay. The starting characteristics of the engine are also improved with this system. When the door is opened the fuel pump is activated for 2 seconds to build-up fuel pressure.
