I changed my battery and my alternator, now my car starts up, but my traction control is off. Hill assist is off my check charging system light comes on still, and I have no power steering and my radio part of my sync system does not come on now. What is wrong?

When the battery is disconnected the car needs to relearn certain operations which by the instruction below seems like all you need to do is drive it. Here is how they save the memory at the shop when doing the work. Check out the video below.

NOTE: When the battery (or PCM) is disconnected and connected, some abnormal driving symptoms may occur while the vehicle relearns its adaptive strategy. The charging system set point may also vary. The vehicle may need to be driven to relearn its strategy.

1. NOTE: When disconnecting the battery cable to interrupt power to the vehicle electrical system, disconnect the battery ground cable only. It is not necessary to disconnect the positive battery cable.

Loosen the battery cable terminal nut and disconnect the battery ground terminal.

- To connect, tighten to 9 Nm (80 lb-in).

2. Loosen the battery cable terminal nut and disconnect the positive battery terminal.
- To connect, tighten to 9 Nm (80 lb-in).

3. To connect, reverse the disconnect procedure.

Battery Disconnect

WARNING: Batteries contain sulfuric acid and produce explosive gases. Work in a well-ventilated area. Do not allow the battery to come in contact with flames, sparks or burning substances. Avoid contact with skin, eyes or clothing. Shield eyes when working near the battery to protect against possible splashing of acid solution. In case of acid contact with skin or eyes, flush immediately with water for a minimum of 15 minutes, then get prompt medical attention. If acid is swallowed, call a physician immediately. Failure to follow these instructions may result in serious personal injury.

WARNING: Always deplete the backup power supply before repairing or installing any new front or side air bag supplemental restraint system (SRS) component and before servicing, removing, installing, adjusting or striking components near the front or side impact sensors or the restraints control module (RCM). Nearby components include doors, instrument panel, console, door latches, strikers, seats and hood latches. Refer to the Description and Operation portion of Restraints and Safety Systems &/or Air Bag Systems for location of the RCM and impact sensor(s). To deplete the backup power supply energy, disconnect the battery ground cable and wait at least 1 minute. Be sure to disconnect auxiliary batteries and power supplies (if equipped). Failure to follow these instructions may result in serious personal injury or death in the event of an accidental deployment.

WARNING: Always lift a plastic-cased battery with a battery carrier or with hands on opposite corners. Excessive pressure on the battery end walls may cause acid to flow through the vent caps, resulting in personal injury and/or damage to the vehicle or battery.
WARNING: Battery posts, terminals and related accessories contain lead and lead components. Wash hands after handling. Failure to follow these instructions may result in serious personal injury.
