Indian Roadmaster Fault Codes
Indian Roadmaster motorcycles have engines, which are made up of many different parts. These parts must work together in order for the engine to function. A problem with one of the parts can make the engine not run. There are many different parts that make up an engine. The following indian roadmaster faults are the list of some of the parts of a motorcycle engine.
What’s wrong with my Indian Roadmaster motorcycle brake light and what can I do about it? There are a few possibilities. One is that your break switch is defective and will need to be replaced. Another is that your brake fluid level may be low.
Indian Roadmaster Faults :
The warning light comes on when one of the various sensors has detected an abnormal condition in the Indian Roadmaster engine's performance. For example, if the oil pressure drops below a certain threshold or if the air/fuel ratio rises beyond a certain point, then this would cause an immediate alert from your vehicle's engine management system.
EFI diagnostic display mode is for informational purposes only. Please see your Indian Motorcycle dealer for diagnostic troubleshooting and repairs. The diagnostic mode is accessible only when the 'Check Engine' light (MIL) illuminates after the motorcycle has been powered on and a code has been set. Leave the ignition on if you want to view the active fault code. The diagnostic mode becomes inaccessible if the motorcycle is powered off and on and the 'Check Engine' light is no longer active. This allows the determination of persistent as well as intermittent faults. Inactive codes are stored in the history of the unit. Please see your Indian Motorcycle dealer to retrieve historical or inactive codes.

These abbreviations, and the accompanying list of trouble codes, can be a great start when your Indian check engine light comes on. As mentioned above, if you are not comfortable with electrical diagnostic work, a dealership or qualified technician can offer assistance. Please keep in mind that even though you have the ability to clear a DTC using the onboard diagnostic feature, you shouldn't clear the code prior to your service appointment. Let the technician view and clear the codes as they troubleshoot the issue.
