Exterior Light Failure Indicator Test

NOTE: System uses a light monitoring control unit and a dash indicator light. When the bulb of an exterior light fails, dash indicator light is turned on.
NOTE: When connecting any additional lighting equipment, ensure power connection is made to fuse circuit ahead of light monitoring control unit. This will avoid malfunction or damage to control unit
  1. Turn ignition switch to "2" position. Indicator light should glow. Light should go out when engine is started. When light is brightly lit, a light failure is indicated.
  2. If light remains lit until ignition switch is returned to "0" or "1" position, a brake light or turn signal light has failed. These circuits are connected to a memory circuit.
  3. With exception of brake lights and turn signals, indicator light will light when any circuit with a failed bulb is in use. Since most circuits have multiple bulbs, a visual check is necessary to determine failed bulb location.
