2005 Harley Road King FLHRI - Diagnostic Trouble Code (DTC) Reference

Delphi EFI, serial bus, plain TSM (no security, no ABS).
Module part numbers on this bike: TSM 68920-01C, Speedometer 67033-04A.

This is a complete table compiled because every other table I could find is the abbreviated one. If you have additions or corrections send me e-mail (see bottom of page).

1. How to Access the Codes

Ignition switch OFF, Run/Stop switch to RUN.
Press and hold the odometer reset button.
Turn ignition switch to IGN, then release reset button. Background lighting illuminates, needle sweeps full range, indicator lamps (battery, security, low fuel, check engine, cruise) illuminate. The word "diag" appears.
Press reset button once - selection menu "PSSPt" appears with the first P flashing.
Each letter is one diagnostic area. Press reset to advance: P -> S -> SP -> t -> P ...
- P = ECM (Electronic Control Module)
- S = TSM (Turn Signal Module)
- SP = Speedometer / Instruments
- t = Tachometer
To read DTCs in the current area, press and hold reset for 5 seconds, release. Code displays, or "none" if clear. Press reset again for additional codes.
Record the codes. NOTE: a "6" in the first digit is actually a "b" - 7-segment display limitation.
If not clearing, press and release reset to advance. Module part number displays, then advances to the next module.
To clear, press and hold reset > 5 sec until "clear" displays. Release.
Ignition OFF to exit.

Current vs. historic: Without Digital Technician, the only way to differentiate is clear -> run a heat cycle -> re-read. If a code reappears it is current. If not it was historic.

After cycling through all four modules, the speedo displays PPU (Pulses Per Unit) calibration value. Not a DTC, just the speedo's calibration constant. Worth recording for reference.

"No Rsp" appears if a module is absent (e.g. tachometer on a bike without one) or if the Run/Stop switch is OFF during the procedure.

3. B-codes - TSM (S module)

This bike has plain TSM (68920-01C), not TSSM/HFSM. Security/accelerometer/antenna codes (B1135-B1136, B1142-B1145) do not apply.

Code	Fault Condition
U1300	Serial Data Low
U1301	Serial Data High
U1016	Loss of ECM Serial Data
U1255	Serial Data Error / Missing response from other module
BUS Er	Serial bus shorted low/open/high (literal display, not a U-code)
B0563	Battery Voltage High
B1121	Left Turn Output Fault - open / under-current. LED bulbs commonly trip this.
B1122	Right Turn Output Fault - open / under-current. LED bulbs commonly trip this.
B1131	Alarm Output Low (if siren wired)
B1132	Alarm Output High
B1134	Starter Output High
B1141	Ignition Switch Low/Open
B1151	Tachometer Output Open
B1152	Tachometer Output Short to Battery
B1153	Tachometer Output Short to Ground
B1155	Speedometer Output Open
B1156	Speedometer Output Short to Battery
B1157	Speedometer Output Short to Ground

Code overlap note: B1151-B1153 codes also exist in HFSM/TSSM modules with different meanings (Bank Angle Sensor faults). On a plain TSM these are tach output faults. Module identity disambiguates.

4. B-codes - Instruments (SP module)

Code	Fault Condition
B1004	Fuel Level Sending Unit Low
B1005	Fuel Level Sending Unit High/Open
B1006	Accessory Line Overvoltage
B1007	Ignition Line Overvoltage
B1008	Reset Switch Closed (stuck odo button)

5. Bike-Specific Notes - 2005 FLHRI

No ABS - Touring did not get ABS until 2008. Menu is PSSPt, not PSSPtb. C-codes do not apply.
Plain TSM, no security - module 68920-01C. Password codes (P1009/P1010) only relevant if a security module had been installed.
LED turn signals trigger B1121/B1122 - the TSM current-sense was designed for ~21W incandescent bulbs. ~2W LEDs read as "open circuit" to the module. Fix permanently with load equalizers/resistors if it becomes recurring. A one-off after years of operation is just noise.
Mechanical "cruise control" - throttle friction screw. P0577 (Cruise Input High) should never appear.
