- Switch off the ignition before connecting or disconnecting the battery, otherwise the engine control module may be damaged.
- A voltage of at least 12.7 V is necessary for satisfactory functioning of the electrical components.
- During some of the tests, a malfunction may be recognized and stored by the control module. At the end of all tests and repairs, the fault memory should be checked and, erased.
- If the engine starts and then stops after malfunction search, repair or tests on components, because the immobilizer is blocking the engine control module. The fault memory must then be checked and, if necessary, the control module adapted.
