Terminals and Reference Values for BCMNKS003S7
CAUTION:

Check combination switch system terminal waveform under the loaded condition with lighting
switch, turn signal switch and wiper switch OFF not to be fluctuated by overloaded.

Turn wiper dial position to 4 except when checking waveform or voltage of wiper dial position.
Wiper dial position can be confirmed on CONSULT-II. Refer to LT- 2 3 8 , "

CONSULT-II Functions (BCM)NKS003S8
CONSULT-II can display each diagnostic item using the diagnostic test mode shown following.
CONSULT-II BASIC OPERATION
Refer to GI-38, "CONSULT-II Start Procedure" .
DATA MONITOR
Operation Procedure
1. Touch “COMB SW” on “SELECT TEST ITEM” screen.
2. Touch “DATA MONITOR” on “SELECT DIAG MODE” screen.
3. Touch either “ALL SIGNALS” or “SELECTION FROM MENU” on “SELECT MONITOR ITEM” screen.
4. When “SELECTION FROM MENU” is selected, touch items to be monitored. When “ALL SIGNALS” is
selected, all the signals will be monitored.
5. Touch “START”.
6. Touch “RECORD” while monitoring, then the status of the monitored item can be recorded. To stop
recording, touch “STOP”.

4. CHECK BCM OUTPUT TERMINAL
1. Connect BCM and combination switch connectors.
2. Turn ignition switch ON.
3. Turn lighting switch and wiper switch into OFF.
4. Set wiper dial position 4.
5. Check BCM output terminal voltage waveform of suspect mal-
functioning system.
OK or NG
OK >> Open circuit in combination switch, GO TO 5.
NG >> Replace BCM. Refer to BCS-15, "
Removal and Installation of BCM" .
5. CHECK COMBINATION SWITCH
Referring to table below, perform combination switch inspection.
