id091900806100

1.  Disconnect the negative battery cable.

2.  Remove the front bumper. (See FRONT BUMPER REMOVAL/INSTALLATION.)

3.  Measure the voltage at each terminal.

•  If the voltage is not as specified in the Terminal Voltage Table (Reference), inspect the parts under “Inspection item (s)”.

•  If the system does not work properly even though the parts or related wiring harnesses do not have any malfunction, replace the headlight cleaner control module.

Note

•  Terminals E and F are used as the washer fluid-level sensor circuit, not as the headlight cleaner control module circuit.
