The lamp goes out immediately after the ignition or does not go on at all. SMPS and LPS seems to work normally. This situation can be the result of a bad lamp or SPG module. See chapter "Start Pulse Generator".

• Install another xenon lamp in case the voltage on the “LAMP OUT” pins is 140 volt and you hear the SPG module three times clicking to ignite the lamp.

• Replace the SPG module in case the voltage value on the “LAMP OUT” pins is 140 volt and you do NOT hear the SPG module clicking to ignite the lamp.

• Replace the LPS modules in case the voltage value on the “LAMP OUT” pins is below 140 volt and the lamp is not ignited.

Note: The ambient noise must be low to hear the SPG clicking in an attempt to ignite the lamp.
