Kia Optima: Inspection
Rain Sensing Wiper
| 1. | In IGN2 ON state, if auto switch input (LIN communication) is ON then both wiper low relay and wiper high relay outputs are controlled by the rain sensor input signal. |
| 2. | If the wiper switch has been
left in automatic mode with the vehicle ignition OFF, and then the vehicle
ignition switch is turned on, a single wipe will be performed.
|
| 3. | A single wipe will be performed
whenever rain has been detected (Rain Detected signal from Rain sensor)
and the wiper switch is moved to the AUTO position. But a single wipe will
not be performed when the wiper switch is moved to the AUTO position and
OFF signal is being received from Rain sensor. But if the wiper switch is
moved to AUTO position for the first time since vehicle ignition switch
is turned on then a single wipe will be performed regardless of Rain Detected
or OFF signal.
|
| 4. | The drive may adjust the rain
sensor performance by adjusting the sensitivity input. When in automatic
mode, the BCM will perform a single wipe each time the sensitivity is adjusted
upward to a more sensitive setting (downward more then one step). This single
wipe will only be performed if Rain Detected signal is being received from
the Rain sensor. If the sensitivity adjustment is adjusted upward more than
one sensitivity, the BCM will only perform a single wipe unless the time
between Increases is more than 2 seconds.

| 5. | Fault strategy for the rain sensor Rain Sensor Fault 1 - Internal Fault Detected This failure is detected when the wiper is in automatic mode and the input faulty rain sensor from the rain sensor has a duty cycle corresponding to Fault 1. The confirmation delay for the failure is of 1 sec.When this failure is detected, the wiper outputs are OFF and the wiper will also do a wipe in slow speed on the transition from sensitivity 3 to sensitivity 2 (Step 2 to 3) in order to signal the presence of this fault. If another sensitivity is set, the wiper won’t make any additional wipe.
This failure is detected when the wiper is in automatic mode and the input faulty rain sensor from the rain sensor has a duty cycle corresponding to Fault 2. The confirmation delay for the failure is of 1 s. When this failure is detected, the wiper outputs are OFF and the wiper will also do a wipe on the transition from sensitivity 4 to sensitivity 3 (Step 1 to 2) in order to signal the presence of this fault. If another sensitivity is set, the wiper won’t make any additional wipe.
This failure is detected when the wiper is in automatic mode and the input faulty rain sensor from the rain sensor has a duty cycle corresponding to Fault 3 or in case the duty cycle of the input faulty rain sensor is 0% or 100%. The confirmation delay for the failure is of 1 s. When this failure is detected, the wiper outputs are OFF. |
