Mazda CX-5 Service & Repair Manual: Discharge Headlight Service Warnings

Discharge Headlight Service Warnings

• When replacing a discharge headlight bulb, performing the servicing with the negative battery cable connected or in a wet work area could result in electrocution. When replacing a discharge headlight bulb, perform the servicing under the following conditions:

• Switch the ignition to off and disconnect the negative battery cable.

• Perform the servicing out of the rain and in a dry work area.

• Thoroughly dry your hands.

• Because the discharge headlight bulb connector instantly produces approx. 25,000 V

  of high voltage, inserting a finger or a tester probe could result in electrocution. When turning the light switch on, do not insert a finger or tester probe into the discharge headlight bulb connector.

  

  
  

• If a discharge headlight bulb is illuminated before completely assembling the discharge headlight related parts to a front combination light, it could result in electrocution. Before illuminating the discharge headlights, completely assemble the discharge headlight related parts to the front combination lights and install the front combination lights to the vehicle.

Discharge Headlight Control Module Servicing Warnings

• If the discharge headlight control module tester is used to do a part inspection or the discharge headlight control module is disassembled, electrocution could result from the high voltage around the module. Do not do a part inspection of or disassemble the discharge headlight control module.

  

  
  

Reusing Discharge Headlight Control Module

• A discharge headlight control module damaged in an accident could leak high voltage around the module and cause electrocution. In addition, even if the discharge headlights are illuminated without any exterior damage to the module, an illumination malfunction could occur after a period of time has elapsed due to internal damage of a module. If a discharge headlight control module is reused, perform the following inspection and verify that the module is not malfunctioning.

• Perform the tests for the discharge headlight bulb several times under cold-bulb conditions (turn off the discharge headlight bulb for approx. 10 min or more

  , then turn it on) and under warm-bulb conditions (turn on the discharge headlight bulb for approx. 15 min or more

  , turn it off for approx. 1 min

  , then turn it on again), and verify that the discharge headlight bulb turns on normally.

• Inspect the discharge headlight bulb illumination until it illuminates evenly directly after cold-bulb illumination for approx. 5 min

  , and verify that the discharge headlight bulb illumination has no flicker or uneven brightness level.

• Equip with normal discharge headlight bulbs and turn them on for approx. 30 min

  , and verify that the illumination condition is stabilized with no difference in brightness level between left and right.
