  2. CHECK HEADLIGHT ECU SUB-ASSEMBLY LH Click here

  3. CHECK HEADLIGHT ECU SUB-ASSEMBLY RH Click here

  4. CHECK HEADLIGHT LIGHT CONTROL ECU SUB-ASSEMBLY

    A000NVLE03

    1. Measure the voltage, resistance and check for pulses according to the value(s) in the table below.

      Tech Tips

      Since the headlight light control ECU sub-assembly is connected to a connector inside the headlight assembly, the voltage, resistance and pulse cannot be checked directly. The voltage, resistance and pulse listed are for reference only.
