ThunderMax VIN ERR - How To Correct VIN Error - Manual

Clearing VIN ERROR Message in Odometer
List of actions required by “model” to clear VIN ERR message in odometer.
All Cable Throttle Models equipped with TMax (Gen II) modules
On Gen II Cable Throttle Models a VIN ERR message in the odometer is occurring because an
H-D accessory Speedo-Tach has been added and the VIN # stored in the (ECM) module does
not match the VIN# in the Speedo-Tach Combo it is married to.
The stored VIN in the Speedo will be from when the Speedo was first installed on the
motorcycle. The VIN number must be matched to what is stored in the Speedo in order to
clear the VIN ERR message.
The VIN# in the Thunder Max module can be changed. If you have not entered a VIN # since
the Speedo was installed, put in the default VIN#
1HD1KB4137Y603371 which is what
the Thunder Max was originally shipped with.
