Code 5646: “lamp - set lamp on failed” (Error)

Situation	Solution
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.	Install another xenon lamp in case the voltage on the “LAMP OUT” pins is 110 volt and you hear the SPG module three times clicking to ignite the lamp. See "Lamps and Lamp House" Replace the SPG module in case the voltage value on the “LAMP OUT” pins is 110 volt and you do NOT hear the SPG module clicking to ignite the lamp. See "Removal of the Start Pulse Generator". Replace the LPS modules in case the voltage value on the “LAMP OUT” pins is below 110 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.
