Check engine light on harley softtail custo 07

Duplicate question already answered

Probably partially seized brake pistons. Take off your caliper and pump the brake lever. See if the pistons move freely and check for corrosion. If they are pitted or rusted you will need to change them. If it is just perished rubbers then a rebuild kit is quite cheap.

check fuse on solenoid relay

many things can cause this ,if you change your seating postion ( lean forward / move backwards does it go away?....

front forks loose at triple tree,
new front / rear tire more aggressive tread than before,
front wheel loose,
worn head bearings,
bent rim,
loose spokes if any,
wrong tire pressures,
loose handle bars
,some new addition to change the handling of the bike , rear seat rest etc,

try changing bulbs wiggle around see if comes on if not pull the assy from between the tanks and check wiring sometimes the sockets the bulbs sit in take a dump if youre inclined replace the sockets if not JP cycles and buy a new one with all new components

then make sure you change plug and make sure the engine oil is not dry ok

Speedo pick up sensor is bad. Replace it.

Check your fuses and for possible shorted or cut wiring.

Have you changed your bars? Check the micro switch behind the brake lever in the housing. Might have moved a bit.
Check that both filaments of the brake light are good and one is not broken.
While you have the brake light cover off check the connectors into the main body of the light. On my Bob (same year) They all plug into there and can be unplugged easily and re-inserted. One might have not been put in all the way home on assembly.
Hope it helps.

fuse their under the seat and their marked good luck
