INSPECTION
While operating the components, check whether the operations are normal with timing chart.
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 intermittent time 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 dependent 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
would be on all the time. This avoids unnecessary clicking of the wiper relay.
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 for is 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
