  A P2308 code is usually defined as "Ignition Coil 'C' Secondary Circuit." This is a generic powertrain code that applies to select modern vehicles that have OBD-II. Your vehicle's powertrain control module (PCM) can store a P2308 if it detects an abnormal voltage condition in the ignition coil's secondary circuit designated with the ...

This code could also mean the transistor inside the engine computer is fried . New PCM/ECM needed .

P2308 Dodge Description The current flow, or dwell, through the primary ignition coil is controlled by the Powertrain Control Module (PCM) by providing a switched ground path through the ignition coil driver to ground. When the ignition coil driver is switched on, current rapidly builds up to a maximum value, determined by the coil inductance and resistance. When the current is switched off, the magnetic field collapses which induces a secondary high voltage surge and the spark plug is fired. This high voltage surge creates a flyback voltage which the PCM uses as a feedback during the ignition diagnostics. The PCM continuously monitors the ignition system for concerns. The P2308 code sets when the PCM detects a short to voltage in the circuit.

Computer Control Module needs to be reflashed it sounds like. The dealer has the required components to fix it

the security light warns you that there is a safety problem and check your guages. Just check the tire pressure and add where it needs it. this should fix your problem. If it continues often then you probably have a slow leak and need tire repair

55 Completion of diagnostic code display

It just says that it completed the diagnostic check (get one everytime you start your vehicle)

open the bonnet then inside you can see the light set just unscrew those and replace it with new ones.

Now you need to run a OBD on board diagnostics scan to retrieve you fault code to resolve and repair your problem.If you have not use of a OBD 2 scan tool perhaps head in to a garage and have it scared they might charge a fee?.

Some jeeps like my dads 93 wrangler is on the drivers side kinda high on transmission

They acually have an Rapid response for this. This should have been replaced before the car was even sold.
