[QUOTE="macleanflood, post: 449439, member: 23653"] Just bought this 2012 JK. 3.8. 6 speed. 30/44. Stock 3.21 gears. Replaced the bald 35s with Mickey's...love them other than they're 33 and 3/4"... should have bought 37s if I wanted 35s. Aftermarket 18" rims. Whole ton of codes: C107C - brake switch 1 bad - end of the switch looks mushroomed so I might start here. C1000 - brake pedal switch 1 performance C2103 - system voltage high C2101 - high battery voltage C121C - Torque requested not possible C1078 - tire revolution range performance U1084 - radio, freedom top is leaking...got a new seal, eventually replacing radio...have a cheap $20 Walmart Dual AV unit and a Schotche tell the can bus the radio exists harness...which might not be doing what it should. P0513, BA124 - incorrect immobilizer key, key code not programmed...Jeep came with an ACE hardware transponder key... another place to start might be a dealer key. JScan can't read the pin. Dealer wouldn't give me the pin either...had to try. C1501, 2, 3 and 4 - tire pressure internal component failure. Tire shop checked all the senders and they're good. Odds of all four readers failing are low...seems to point to a wiring issue. Speedo is off despite setting it correctly and incorrectly in JScan. Using an endorsed reader. TPMS light started coming on after the new tires...and after I switched it back on after some trails running 15psi. Original tires were from 2011. Discount Tire had fun debeading them. Thoughts? -Mac [/QUOTE]
