Component Inspection

Check Rainsensor
1. Connect scantool to Data Link Connector (DLC).
2. Ignition "ON" & engine "OFF" & wiper "AUTO".
3. Measure waveform between terminal "4" of rainsensor and chassis ground while sprinkling water on front window glass.

Specification : Duty cycle > 66.7% ± 3%

FIG.1) Duty cycle of rainsensor as a function of sensor mode.
4. Is the measured waveform within specifications?
** Duty cycle value will be fixed at 38.0% ± 3%, if fault 2 is detected.
