INSPECTION

BCM FUNCTION

1. Vehicle speed sensing intermittent wiper
Vehicle speed is determined by number of speed sensor pulses input in one second. The current speed and
the previous speed for the vehicle is to be compared. The higher of the two values is to be used in the
intermittenttime calculation. The previous value is updated every second.
When Ignition 2 is on and the wiper switch is in the intermittent position, the wiper shall operate with speed
dependant intermittent time. A single wipe is achieved by driving the wiper relay until the park switch is able to
take over unless the dwell time between wipes is too short. In this case it wouldbe on all the time. This avoids
unnecessary clicking of the wiper relay.
Time specification
T1 : Max. 0.5 sec.
T2 : 0.6~0.7 sec. (Time of wiper motor 1 rotation)
T3 : At vehicle speed = 0km/h.
2.6±0.7 sec. (VR=0k )~18.0±1sec (VR=50K )
At vehicle speed = 100km/h or more.
1.0±0.2sec (VR=0k )~10.0±1sec (VR=50K )
2. Washer linkage wiper
IG2 must be on for this function to operate.
When the washer switch is on for more than 0.3 sec, the wiper output is activated immediately. The length of
time the washer switch is held foris then evaluated to determine the number of swipes required.
If the washer switch is on for more than 0.2 but less than 0.6 sec, then wiper performs a single swipe.
Alternatively, if the washer switch is held for more than 0.6s then the wipers must finish the current swipe
theperform another two swipes.
If washer switch is on less than 0.2 seconds make no wiper action.
During intermittent wiping, a washer linkage wipe has higher priority.
