Toyota Sienna Service Manual: Precaution


  1.  When any defects such as deformation, crack, dent, chipping, etc. are identified on the discharge headlight (especially, on the light control ECU), replace it with a new one.
  2.  Even if the operation seems to be normal, the failsafe function may be defective.
  3.  Be careful not to scratch or drop bulbs of the discharge headlight and halogen bulbs (for headlights and fog lights) as they have pressurized gas inside and can be easily broken.
  4.  Touching the HV socket of the discharge headlight with the headlight dimmer switch ON could generate momentary high voltage of 20,000 V and lead to a serious injury.
  5.  Never connect a tester to the high voltage socket of the discharge headlight for measurement, as this leads to a serious injury because of high voltage.
  6.  When performing operation related to the discharge headlight, keep it away from water including rain, turn off the light control switch, and disconnect the battery terminal and the connector of the light control ECU in advance to avoid electric shock.
  7. When performing operation related to the discharge headlight, start it after assembling is completed and never turn the lights on without a bulb installed.
  8.  Do not turn the discharge headlight on using another power source except vehicle's.
