b.    When grounding G/L: "STND" monitor goes off.

Operates as specified in a. and b. 

•   Side-stand switch is faulty.
•   Black lead is broken.

 

Measure voltage between G/L and B on harness side.    
Less than 12V    
Disconnect the G/L lead from the 9-P coupler (on the monitor side) in the headlight body, and ground it.
Operates
•   Green/blue lead is broken.
Does not operate    

•   CMS is faulty.

*Engine running

Disconnect the connector of white/black lead 
(adjacent to the brake master cylinder) in the headlight body. 

 

 

Ground the W/B female connector with a jumper wire

Operates 

•   Brake level sender is faulty.
•   Black lead is faulty.

 

Does not operate

 

 

Disconnect the W/B lead of the 9-P coupler (on the monitor side) in the headlight body, and ground it.

Operates

•   White/Black lead is broken.
