Disconnected and reconnected battery/messed up transmission display

Disconnecting the battery can sometimes cause the vehicle's computer to reset, which can result in it entering "limp mode" to protect the engine and transmission. This mode is designed to limit the vehicle's speed and power to prevent further damage until the underlying issue is resolved.
To get your truck out of limp mode, you may need to reset the vehicle's computer by following these steps:

1. Turn off the engine and remove the key from the ignition.
2. Disconnect the battery terminals (both the positive and negative cables).
3. Touch the positive and negative cables together (away from the battery) to discharge any remaining energy in the system.
4. Wait for at least 15 minutes before reconnecting the battery terminals (first the positive and then the negative).
5. Start the engine and see if the limp mode has been resolved.

Was this message out of the blue or did you repair or remove something? This procedure may help.
1. Disconnect battery for 1-2 hour. (Some people have stated for faster results. To remove both cables and connect battery leads (short them) with a jumper wire - removes any residual current. Wait 5-10 minutes). I don't like shorting cables together, personal preference.
Reconnect battery, place key in ignition & initiate reprogramming sequence.
3. Sequence = turn key to "ON" position only, wait 10 seconds. Repeat 5 times.

A Toyota will not run with the battery disconnected, it doesn't mean an alternator problem only a voltage and load test can determine that, it is unique to S\some Japanese cars and light trucks.

WARNING: Batteries normally produce explosive gases which can cause personal injury. Therefore, do not allow flames, sparks or lighted substances to come near the battery. When charging or working near a battery, always shield your face and protect your eyes. Always provide ventilation. Failure to follow these instructions may result in personal injury.
WARNING: Keep body from under the auxiliary or secondary battery when disconnecting or reconnecting the auxiliary battery safety straps since the battery weighs 50 pounds and bodily injury can result. Failure to follow these instructions may result in personal injury.

1. CAUTION: Failure to accurately follow the battery disconnect procedures described in this section may result in vehicle or component damage.
   NOTE: The preferred method of service requires the use of a floor hoist to lift the vehicle overhead, and a transmission jack to support and lower the auxiliary battery case.
   NOTE: The auxiliary battery can be charged while the auxiliary battery safety straps are connected to the vehicle. Follow the procedures up to and including disconnection of the auxiliary battery cables.
   Disable the vehicle electrical supply. For additional information, refer to Dual Battery Disconnect in this section.

1. Remove the 2 auxiliary battery cable harness screws retaining the harness to the frame.

1. Support the bottom of the auxiliary battery and case with a transmission jack.

1. CAUTION: To prevent possible damage to the auxiliary battery case, cover the battery cables during the lowering process. It is recommended to loosen the auxiliary battery case cover bolts before lowering the battery box.
   Remove the auxiliary battery case from the frame.
   1. Remove the upper RH auxiliary case -to- frame bolt.
   1. Loosen, but do not remove, the 3 remaining battery case-to-frame bolts.
   1. Raise the battery case up and to the right to dislodge the battery case from the 3 remaining bolts.

1. Lower the auxiliary battery and case until tension is present on the safety straps.

1. Remove the 2 bolts and disengage the battery case cover.

1. Remove the auxiliary battery cables.

1. Remove the 2 auxiliary battery case safety strap to frame bolts.

1. Remove the hold-down wedge.

1. WARNING: When lifting a battery, excessive pressure on the end walls could cause acid to spew through the vent caps, resulting in personal injury. Lift with a battery carrier or with your hands on opposite corners. Failure to follow these instructions may result in personal injury.
   Support the battery and case with a transmission jack. Disengage the safety straps and roll the auxiliary battery and case on the transmission jack away from the vehicle.

Disconnect the postive battery connection again and leave it disconnected for at least one minute.
Reconnect the battery connection and start it up.

if your battery died or you replaced battery, disconnect the postive terminal from battery. insert key into igniation to on position (not start) then reconnect the battery postive terminal.

Sometimes the alarm gets tripped when the battery has been disconnected as the system thinks someone is trying to steal the vehicle when it loses power. Usually if you reconnect the battery [and the alarm sounds] then lock and unlock the drivers door with the key or the remote on the key fob it will reset the alarm and everything will work again. I've had to try a couple of times to get these systems to reset so you may have to do the same. There may also be a procedure listed in your owners manual for this situation so I'd take a look there too. Good luck, hope this helps out!

disconnect battery cables, clean all components with baking soda and water mixture, use wire brush, corrosion could be in side cable under plastic coating

I believe the 32 code is for an open circuit on the driver side.
I have had similiar issues on my 2002 Ford Escape.
Try disconnecting the negative battery terminal for about 15 minutes (don't mess with airbarg cables while battery is connected), then check the plug and cables underneath the driver's seat. If you can't see the problem, disconnect the cable (should be yellow) and reconnect.

It shouldn't be,however.....when replacing batteries,or simply disconnecting and reconnecting to clear a code for example,always hook up the positive terminal first and the negative terminal last,and,with the ignition OFF.Infrequently,if a battery is hooked up with the key in the ON position,it can damage the vehicles computer....(PCM,TCM,BCM,etc etc)And the reason for hooking up the negative terminal LAST is to avoid arky sparky's off of your wrench which can also damage the vehicle's computer (s).Try disconnecting both negative terminals of both batteries and let sit for minimum 20 minutes,then reconnect,and see what you have.
