Physical Values
CAUTION:
- Check combination switch system terminal waveform under the loaded condition with lighting switch, turn signal switch and wiper switch OFF is not to be fluctuated by being overloaded.
- Turn wiper intermittent dial position to 4 except when checking waveform or voltage of wiper intermittent dial position. Wiper intermittent dial position can be confirmed on CONSULT. Refer to CONSULT FUNCTION (BCM - COMB SW) .
- BCM reads the status of the combination switch at 10 ms internal normally. Refer to SYSTEM DIAGRAM .
