- Check resistance between steering switch connector termina

2.CHECK HARNESS BETWEEN COMBINATION SWITCH (SPIRAL CABLE) AND BLUETOOTH
CONTROL UNIT
- Turn ignition switch OFF.
- Disconnect Bluetooth control unit connector B131 and combination
switch (spiral cable) connector M30.
- Check continuity between Bluetooth control unit harness connector
B131 and combination switch (spiral cable) harness connector M30.
- Check continuity between Bluetooth control unit connector B131 and
ground.
