No. All you can do is replace the TPS. Throttle Position Sensor. Throttle bodies cannot be programmed or reset. All you can do to a throttle body is take it apart and clean it. Just replace the TPS.

Press the turtle? Could be many things, such as bad TPS, MAF, leak in hose between MAF and throttle body, vacuum leak, coolant temp sensor, bad catalytic converter or muffler. Any codes set?

Well, check if you have brake lights to start with? If you dont have brake lights, it is possibly a brake light switch under the brake pedal or a stop fuse blown. ( with brake switch malfunctioning, this could set ur check engine light and also ur brake and abs light. Check this and get back to me. By the sounds of the other accessories not working, check your 10 amp guage fuse which i am not quite sure, could be under the hood or in the cabin. keep me updated.

Suspect a drive shaft if brakes on throttle whilst braking stops it but would need a good look to have sort of idea ,and iam in spain so please consult a local mechanic

Check temp sensor and TPS, throttle positioning sensor.The power control module,"pcm.is a possible thought.Just check all connections. It is always a good idea to spray WD 40 or equivalent in the connections.

Then the job either wasn't done correctly or you have
ABS System problems

You need professional tools to work on ABS

First, it is under warrantee I assume

The wrench light as I hope you found in your
owners manual, is an indication of a fault
code set,if the light stays on. Even if it went
off, the data can be found with a professional
scan tool, unless you disconnect the battery
or clear the codes. Never do that. You need
them to diagnose the issues

You went into ETC Failsafe, by the sounds of it

That could be a bad ignition coil
Rare possiblity, the TPS or Throttle Body Motor
the vehicle is too new for anything but coil issues

Need those codes

You know we have had these OBD Systems since
1983 model,that is 30 years,lots of time to get up to
speed on how things work

Throttle position sensor TPS is probably defective.
have the ECU scanned for codes and do the repairs the codes dictate.
