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 inter-
mittent dial position. Wiper intermittent dial position can be confirmed on CONSULT -III. Refer to
BCS-24, "
COMB SW : CONSULT-III Function (BCM - COMB SW)".
BCM reads the status of the combination switch at 10 ms internal normally. Refer to BCS-7, "
System
