Help with codes!

[09jkumct]

Hi,
Yesterday, got my 2009 JKU (apologies I know this is TJ discussion) back from the workshop (lots of misfire issues). They managed to fix these issues. However, I just took it to get valeted and when I switched the car back on my engine light came on!
I ran j-scan and got the following codes:
P2098
P0420
C1405
C1008
B2102
Can anyone advise if there’s a link between these codes? Really don’t want to have to send it back to the workshop.
TIA
ps. I’m in the Middle East

Wow. That ranges from wheel speed sensor, cat issues, radio antenna, brake fluid too high, and wheel speed sensor? Guess I’d try for loose battery terminal or even a battery issue. If you reset the codes do they come back?

Doesn't matter what year it is. Doesn't matter which vehicle. It's usually grounds, grounds, grounds.

On my wife's JK we were convinced the ABS module had failed.

Turns out I had used it's ground for the locker wiring I installed and it loosed up.

Tightened it back up (after about 6 hours of diagnostics and searching) and bingo, no more issues.

Well other than the wheels came off a 2012 and I think they changed the TPMS system in 13 so it can't read the sensors. But hey ...

You’re being an ass AGAIN! Of course they have camels there!
