Help with DTC Codes (MUSTANG GT 2021)

[xVolaft]

There are 2 DTC alarms that I don't know how to deal with in Mustang GT Base Model 2021.
No dashboard lights or issues while driving were observed, just using the scanner.

Scanner used: MaxiSys MS909EV V5.10

DTC reading:

1- PSCM (Power Steering Control Module):
C1B00 - Steering Angle Sensor

2- TCU (Telematic Control Unit):
B1D55 - Antenna #2

Can someone explain what are these, and how to overcome these problems, cost.

UPDATE: I cleared the DTC and everything is normal, no more codes, FOR Power steering control module, wheel alignment needs to be done (read the codes with FORSCAN, they explain why you are having the code).

I'm enclosing some information related to item #2, the TCU.

The thread above covers the topic of the TCU and how many have elected to disable the system in its entirety.

The TCU itself is in the trunk. It is powered by and associated with fuse #8/9 within the Passenger side fuse panel, interior of the car (associated with the Body Control Module A). The Owner's manual lists the fuse position. The Passenger side fuse panel is located near where the passenger would place their right foot.

The TCU is attached to a splitter in the trunk. This splitter branches left and right, supporting left and right cell antennas. If you've used the Ford Pass App before, the TCU and these antennas are how the car talks to Ford.

I'd try pulling the fuse first, wait a bit, then re-insert, re-initializing the TCU and bits. If that does not clear the code, it's probably best to begin reviewing the physical connections, to see if anything has loosened over time. Then, consider actual antenna replacement. FWIW, you have one working antenna.

Edit: 2021. Has your warranty passed?

Just drive the car if you aren’t having issues.

Have you tried clearing the codes?
Did they return?
As suggested above, I'd consider clearing the codes and driving the car.
The telemetrics is a nuisance but unimportant to vehicle operation.
The steering angle one could be a one-off occurrence or point to something more serious. I found this in another forum and it appears the guy had access to a Ford diagnostic manual. It's pretty long but might give you stuff to check.

"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."

Definitely try clearing the codes and see if they return.
If they come back, investigate further but something as silly as a weak battery will trip all kinds of whacky codes internally.
