DTC Code C1B00

I had the car at the Ford dealer today for a C1B00 code which is associated with a steering angle sensor fault which can be caused by a few issues and the most common issues are described below following by a newer update,still waiting on what the exact issue,stay tuned.  Z   DTC C1B00:2F (Steering Angle Sensor: Signal Erratic) - If the signal is calculated to be outside the expected range, DTC C1B00:2F will be set. If the tie rods (inner or outer) have been incorrectly installed or if the vehicle has sustained damage to the EPAS gear and/or associated steering/suspension components, DTC C1B00:2F may set.
DTC C1B00:62 (Steering Angle Sensor: Signal Compare Failure) - If the calculated signal does not match other sensor input, DTC C1B00:62 will be set.
DTC C1B00:64 (Steering Angle Sensor: Signal Plausibility Failure) - The PSCM calculates an absolute steering position offset based on several inputs, when the steering wheel compensation message from the ABS module matches or exceeds this calculation, the PSCM sets this DTC. Torque steer compensation is suppressed for the remainder of the ignition cycle in which DTC C1B00:64 is set.

Possible Causes Inner tie rods
Steering gear internal failure.
PSCM internal failure
DTCs present in the ABS module.
ABS module HS-CAN bus concern.

Diagnostic Aids When DTC C1B00:2F is set, the PSCM will transmit an invalid steering angle message over the HS-CAN bus.
When DTC C1B00:62 is set, the PSCM will remove steering assist, and enter into a manual mode and transmit an invalid steering angle message over the HS-CAN bus. The PSCM will also send a message to the IPC to display the POWER STEERING ASSIST FAULT message in the message center.
DTC C1B00:64 indicates a possible measurement or calculation error between the PSCM and the ABS module. Torque steer compensation is suppressed for the remainder of the ignition cycle in which DTC C1B00:64 is set. This DTC is for information only. Do not install a new PSCM for PSCM DTC C1B00:64                      [UPDATE] If DTC C1B00 is setting it is suspected there is likely an intermittent ABS/ADV TRAC/steering fault occurring. If you refer to section 206-09 of the online workshop manual DTC C1B00 sets as a result of a steering wheel angle, accelerometer and WSS input correlation issue. This DTC can be caused by a wheel/tire issue, chassis modifications, a faulted EPAS steering gear, a faulty SCCM, a faulty RCM or a WSS/tone ring/wheel bearing issue. In order to accurately diagnose this concern it will need to be present at the time of testing, otherwise your test results will be inconclusive with no problem found.

Before any further diagnostics inspect for any chassis modifications on this vehicle (i.e. lowering kits) and ensure that the tires on this vehicle are the factory original size, sufficient tread remains, that they are inflated to specification and that their circumferences are all within ½" of one another and replace any affected tire(s) as needed.

If you can verify that chassis modifications and the tires aren't at fault monitor the steering angle PID'S in the PSCM and SCCM, the accelerometer PID'S in the ABS module (YAW, LAT, LONG, ROLL) and the WSS PID'S in the ABS module and note for any false readings when this concern occurs. Note it is normal for the steering angle PID'S to not read 0° with the steering wheel straight ahead due to the way that this position is recalculated on each key cycle. Also note that the accelerometer PID'S will need to be monitored at a standstill immediately after this concern occurs and they should read close to or at 0 with minimal fluctuation (note for difference in reading when this concern is not occurring vs. is occurring). If a faulted steering angle input is found, and depending on where the false input is originating, replace the affected component as needed (EPAS steering gear or SCCM w/ steering angle sensor). If a false accelerometer input is found suspect the RCM is at fault. If a false WSS input is found suspect a WSS/tone ring/wheel bearing issue and repair accordingly. [Stay tuned]

I just wanted to give a quick update on the situation on hand.....my local tuner friendly dealer cleared the codes and wants me to monitor and check to see how fast code C1B00 AND B1215 RETURN and within 24hrs had both codes set and now he wants me to clear the codes and monitor for codes on (stock tune) which is quite upsetting pulling a full trailer of cattle for roughly almost a week of driving stock tune and cannot get the car to set off any codes[NADA,ZERO]IDK.and guess they need to verify complaint and confirm as per esp warranty prior to coverage or any claims that can be made.....any thoughts?  Z    BTW Big prop's to Mike from www.ecopowerparts.com and his DP.  Z

Sometimes the tune simply needs to be reloaded.  In one case, the B1215 occurred because the tune was sent for a 2 bar instead of 3 bar MAP!

If tuned:  Take note of the strategy code as you return to stock (including 3 bar MAP to 2 bar MAP) -> take car in & get it serviced -> check strategy code when you get car back -> have tuner update your tune if the strategy code has changed -> reload tune -> ENJOY!
