MONITOR DESCRIPTION
This DTC indicates that the stop light switch remains ON. When the stop light switch remains ON during "stop and
go" driving, the ECM interprets this as a fault in the stop light switch and the MIL comes on and the ECM stores
the DTC. The vehicle must stop (less than 3 km/h (1.86 mph)) and go (30 km/h (18.65 mph) or more) 5 times
for 2 driving cycles in order to detect a malfunction.
