Check for a spark across the tips of spark gap SP-02 after making the appropriate connections via start-up transition or by means of active diagnosis in CONTROL UNIT TEST mode. In the case of start-up transition, the petrol/methane solenoids supply pump must be interrupted so as not to damage the Lambda sensor or catalytic convertor.
