How To Repair Harley Road Glide Special Won't Start & No Lights

Oh no. We've all been in that location. The bank check engine lite (CEL) on your dash illuminates, and your Harley-Davidson isn't running correct. Or, what might be fifty-fifty more confusing, the light comes on but the wheel seems completely fine. What should you lot practice, what does information technology mean? Is this cause for a tow? Can the bike operate commonly until you lot can get it into a shop?

These questions are very common when a Harley-Davidson check engine light comes on. Keep reading below for information most how to determine which trouble code is associated with the CEL.

What Does a Cheque Engine Light Mean?

An illuminated check engine calorie-free is an indication that the motorcycle'due south onboard diagnostic system detects a electric current or celebrated trouble code, known as diagnostic trouble codes (DTC).

Once exclusive to the automotive industry, motorcycle manufacturers like Harley-Davidson rely on onboard diagnostics to assist owners and technicians when a fault occurs.

Prior to electronic fuel injection (EFI), motorcycles had few, if whatsoever, sensors or complicated electronic equipment. Over the years, manufacturers like Harley-Davidson transitioned to fuel injection for a variety of reasons, including reliability, simplicity, fuel economy/emissions, and functioning.

While this transition to EFI gave riders a simpler and more enjoyable ownership experience, it also made diagnostic piece of work more challenging. Post-obit the trend of automotive manufacturers, motorcycle manufacturers like Harley-Davidson adopted the standardized SAE convention for identifying and labeling onboard faults.

If the vehicle'due south electronic control module detects an mistake within the system, it "throws a code," causing the cheque engine light to illuminate. A DTC is directional information for an possessor or technician to brainstorm diagnostic work. The presence of a lawmaking doesn't hateful you lot should commencement replacing parts. A Harley-Davidson dealership service department or other qualified technician is your all-time bet if yous are not comfortable or experienced with diagnosing electrical issues.

Lawmaking categories: (categories may vary based on model yr and options)

• Engine Control Module (ECM)
• Body Control Module (BCM)
• Speedometer (SPDO)
• Radio (RAD)
• Anti-Lock Braking System (ABS)
• Plough Signal Security Module (TSSM)

All fuel-injected motorcycles have the ability to communicate trouble codes. However, some bikes require an external diagnostic tool. Luckily, Harley-Davidson® motorcycles accept the ability to brandish codes right on the dash, no tool required!

To enter the diagnostic system and retrieve a trouble code, hold down the trip reset button while turning the ignition from off to on. This will permit you to cycle through the categories, and meet which one indicates a lawmaking.

Trouble Code Categories

Trouble codes autumn into ane of three categories:

• Current
• Historic
• Pending

Current codes display when the organization detects an active fault. Simply clearing the code won't resolve the issue, as the code will return in one case enough drive cycles occur in which the organisation recognizes the error again.

Historic codes remain saved until they are intentionally cleared or roughly 40 ignition cycles (on/off) without recurrence. Historic codes assist with intermittent issues or faults.

Pending codes record when the organisation detects a mistake just the fault has not occurred during enough drive cycles to set at electric current. If the fault resolves itself, the lawmaking volition get a historic lawmaking, skipping current condition.

How to Display Trouble Codes

Using the trip reset push button, a Harley-Davidson possessor can cycle through codes in each of the lawmaking categories and note the DTC itself. Listed beneath are possible codes and their meanings. Delight note that not all codes volition apply to every model based on year and options.

How to access codes without a diagnostic tool:

1. Start with a known good battery and secure battery terminals
2. Set run/stop switch to run position
3. Hold downwardly the trip reset button while turning the ignition to on position
4. Click the trip button to cycle through modules and hold down trip push button to brandish codes (displayed text will vary based on year and model)

Newer bikes display abbreviations to represent each module:

• ECM: Electronic Command Module
• BCM: Body Control Module
• SPDO: Speedometer
• RAD: Radio

Older bikes display letters to correspond each module:

• P: ECM
• S: TSM/TSSM
• SP: Speedometer
• T: Tachometer
• B: ABS module

The onboard diagnostic organization will too display a part number that corresponds to the problem code, and information technology volition allow yous to clear the code. This function can be a bit tricky, since the part associated with the displayed number isn't automatically bad. Also, it'southward possible to run across multiple codes related to i upshot.

Harley-Davidson uses abbreviations in their service manual, owner's manual and for diagnostic work with trouble codes. We've listed mutual abbreviations and their meanings below:

• ABS: Anti-Lock Braking Organization
• ACR: Automatic Compression Release
• AFR: Air Fuel Ratio
• AIS: Agile Intake Solenoid
• ATS: Air Temperature Sensor
• BAS: Banking company Bending Sensor
• BCM: Body Control Module
• Can: Controller Area Network
• CCM: Cruise Control Module
• CKP: Creepo Position Sensor
• DLC: Datalink Connector
• DTC: Diagnostic Problem Codes
• ECM: Electronic Command Module
• ECT: Engine Coolant Temperature
• ECU: Electronic Control Unit
• EFI: Electronic Fuel Injection
• EFP: Electronic Fuel Pump
• ET: Engine Temperature sensor
• FI: Fuel Injectors
• FPR: Fuel Pressure Regulator
• H-DSSS: Harley-Davidson® Smart Security Organization
• HCU: Hydraulic Control Unit, ABS
• HFSM: Easily Costless Security Module
• HO2S: Heated Oxygen Sensor
• IAC: Idle Air Control actuator
• IAT: Intake Air Temperature sensor
• ICM: Ignition Command Module
• IMAP: MAP + IAT in one unit
• ISS: Ion Sensing System
• JSS: Jiffy Stand up Sensor
• LHCM: Left Hand Command Module
• MAP: Manifold Absolute Force per unit area sensor
• MHR: Right Hand Control Module
• RCM: Reverse Control Module
• TCA: Throttle Control Actuator
• TGS: Twist Grip Sensor
• TMAP: Intake Air Temperature / Manifold Absolute Pressure equipment
• TPS: Throttle Position Sensor
• TSM / TSSM: (Plough Signal / Turn Betoken Security Module)
• VE: Book Efficiency
• VIN: Vehicle Identification Number
• VSS: Vehicle Speed ​​Sensor
• WSS: Bicycle Speed ​​Sensor

These abbreviations, and the accompanying list of trouble codes, can exist a bang-up get-go when your Harley-Davidson check engine light comes on. Every bit mentioned higher up, if y'all are non comfortable with electrical diagnostic work, a dealership or qualified technician can offer aid. Please keep in mind that even though you lot have the ability to articulate a DTC using the onboard diagnostic feature, you shouldn't clear the code prior to your service appointment. Allow the technician view and clear the codes as they troubleshoot the issue.

How Does This Use to a Career in the Field?

Some Harley-Davidson owners perform their own service and repair, but near draw the line at electrical diagnostic work. Technicians who can quickly diagnose and repair electronic organisation faults are ever in demand. Simply observing and identifying a lawmaking isn't enough to fix a motorbike with an illuminated check engine light, nor is swapping out parts without a thorough understanding of the root cause of the failure. Similar anything else, experience and practice volition allow for an entry-level technician to become a full diagnostic tech.
