t  During some checks, it is possible that the control unit will detect and store a fault. Therefore, after completing all checks and repairs, read the fault memory and clear if necessary → Chapter.
t  If, after fault finding, repairs or component tests, the engine starts, runs for a short period and then stops, then the fault may be that the immobiliser is blocking the engine control unit. In this case, the control unit must be adapted.
