Diagnosis ProcedureINFOID:0000000001451494
1. CHECK LIGHT & TURN SIGNAL SWITCH
Check operation with normal light & turn signal switch installed.
Does it operate normally?
YES >> Replace light & turn signal switch. Refer to EXL-101, "Removal and Installation".
NO >> GO TO 2
2. CHECK WIPER & WASHER SWITCH
Check operation with normal wiper & washer switch installed.
Does it operate normally?
YES >> Replace wiper & washer switch. Refer to WW-76, "Removal and Installation".
NO >> GO TO 3
3. CHECK SWITCH BASE (SPIRAL CABLE)
Check operation with normal switch base (spiral cable) installed.
Does it operate normally?
YES >> Replace switch base (spiral cable). Refer to SR-7, "Removal and Installation".
NO >> Combination switch is normal.

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, "
