Time to pour some fuel on the fire!

Presenting the one and only HOSS 2.5 Steering Rack brought to you by @NORCALGXP and Hamm's an America's Classic Premium Beer Born in the land of sky blue waters.

Hoss 1.0 Motor bolted to a HOSS 3.0 rack. Fault codes are below and looks like there is a steering position sensor inside the clock spring. I think this is a very important discovery as there are 2 separate clock springs for the bronco. I have a feeling this is related. Plugged into my bronco for testing.

Next phase since discovery the codes will be install and testing. So at this point if you do a motor swap you may not need to program the rack. This is pretty big as it will allow more flexibility with a trail repair or make your own HOSS 2.5 rack.

Nice work @Snacktime
Hell ya, I might not have the bigger steering assist for Moab, but maybe if this works out I will have the case and tie-rods. Got to love that sky-blue water.

Next phase will be a full install, since discovering the codes are related to the steering wheel clock spring. So at this point if you do a motor swap you may not need to program the rack. This is pretty big as it will allow more flexibility with a trail repair or make your own HOSS 2.5 rack.

When you say "fancy Broncos" what do you mean?

These fancy buttons, I really don't know what they do? Ohh fancy Broncos have cameras, mine has a camera.

Ford Bronco HOSS 3.0 severe duty STEERING RACK and TIE RODS ...Ford Performance M-3200-WT Screenshot_20230324-191749~2

So you're saying if I buy a HOSS 3 rack, swap my motor, I wouldn't have to reprogram anything?

But I guess I have some of those fancy buttons. I don't know what the top button is cuz I don't have that one, but the one on the left is cruise control and the one of the ride is lane keeping assist

From shop manual, via Alldata:

PINPOINT TEST X: PSCM (POWER STEERING CONTROL MODULE) DTC (DIAGNOSTIC TROUBLE CODE) C1B00:49 STEERING ANGLE SENSOR
NOTE: Refer to Steering GSB for additional connector and wiring inspection tips.
Refer to Wiring Diagrams Cell 43for schematic and connector information.
Normal Operation and Fault Conditions
REFER to: Power Steering - System Operation and Component Description (211-02 Power Steering, Description and Operation).
Description
  • Description
  • While the ignition is ON and the voltage supply to the PSCM is above 6 volts, the module monitors the motor inside the EPAS gear to calculate the relative and actual steering wheel angle. This value is transmitted to other modules over the HS-CAN .
Pinpoint Test Applicability
  • Pinpoint Test Applicability
  • This test applies to PSCM Diagnostic Trouble Codes (DTCs) C1B00:49 only. IT DOES NOT apply to any other modules or Diagnostic Trouble Codes (DTCs).
DTC Diagnostic Strategy
  • DTC Diagnostic Strategy
  • If the module DTC list results in a large number of Diagnostic Trouble Codes (DTCs), diagnose all module hard faults first (C102D, C1B00, C200B, C200C, C200D, U2011 and U3000) before diagnosing any network faults (lost communication or invalid data). If voltage concern Diagnostic Trouble Codes (DTCs) are present, diagnose those after any module hard faults and before any network faults. Diagnose all current and active Diagnostic Trouble Codes (DTCs) before diagnosing any historic Diagnostic Trouble Codes (DTCs).
Pinpoint Test Purpose
  • Pinpoint Test Purpose
  • Verify PSCM DTC C1B00:49 is present. Verify PSCM wiring harness and electrical connectors are in good condition.
Diagnostic Aids
  • Diagnostic Aids
  • When DTC C1B00:49 is set, the PSCM removes steering assist, enters into manual mode and transmits an invalid steering angle message over the HS-CAN . The module also sends a message to the IPC to display POWER STEERING ASSIST FAULT in the message center.
  • If a damaged bellows boot(s) was discovered during inspection and this pinpoint test DOES NOT lead to the installation of a new EPAS gear or bellows boot(s), ADDRESS the damaged boot(s) before returning the vehicle to the customer.
DTC Fault Trigger Conditions
DTCDescriptionFault Trigger Condition
PSCM C1B00:49Steering Angle Sensor: Internal Electronic FailureThis DTC sets if the sum of the 2 steering shaft torque sensors do not equal a specified voltage level. This can occur if the wiring harness is damaged, chewed or the connectors are loose or damaged. An internal steering gear or PSCM fault can also cause this DTC set.
Possible Sources
  • Steering gear internal failure
  • PSCM internal failure
NOTICE: Use the correct probe adapter(s) when making measurements. Failure to use the correct probe adapter(s) may cause damage to the connector.

Looks like you still have a problem internal to the rack...But 10 out of 10 for effort!

U3001 you can most likely disregard, was most likely set when the rack was plugged in and disconnected again

@Bmadda

The error could very well be from when I broke my rack the first time 🤣 this is a used part! I am thinking a fresh programming is a solid option at this point. I couldn't clear the error with Forscan and we didn't have time to waste $50 on FDRS subscription.

That was kinda my point, if you can't clear it, it's a hard fault, not something left in memory from a previous failure. I think what you are trying to do CAN be done, but the issue w/NORCALGXP's rack wasn't in the motor, it was in the steering angle/torque sensor assy up in the pinion tower. If you had "known good" parts, you might be able to make it happen! The fact that you got communication is a breakthrough! You could try a reflash just to prove that it will accept the BL/2.0 PMI. My guess is it will NOW reject the WT 3.0 and only accept PMI for your original VIN. Try both ways when you renew your FDRS! An experiment that is definitely worth $50!

Maybe the PSCM is programmed differently for Lux vs Mid vs High. If that is the case, then we might need package specific VINs to correctly program the rack.

@NORCALGXP pin out of the motor is bad. This swap allows us to plug in the pecker head wiring harness.

Programming is the same, I know the clock spring is different between models.
