What it means
Common causes are a failed fan relay, wiring/connector faults, or a failed cooling fan. This is a generic Suzuki fuel-injection (FI) code, so it applies across Suzuki FI models — the Raider R150 Fi, Smash, Gixxer, GSX-R and GSX-S range, V-Strom, and more. Suzuki reports it as a "C" number, shown through the FI-light blink pattern or by entering the bike’s dealer/diagnostic mode. After the fault is repaired it becomes a stored "history" code; clear it through Suzuki’s dealer/diagnostic mode so the FI light goes out.
Symptoms
- FI light on with code C60

Frequently asked questions
Is C60 why my bike overheats in traffic?
It can be — if the fan relay isn’t switching the fan on, the engine loses low-speed cooling. Test the relay first; it’s the common cause.
