code 12
I don't know what year your truck is but:
<H1 align=center>Fault Code 12</H1>
<H3>Synopsis</H3>
Description: Memory standby power recently lost
Power loss light: Off
Limp-in mode: None</P>
<H3>Possible Causes</H3>
Battery or power line recently disconnected - This code is normal if the electrical system has been worked on or the battery has recently been disconnected. It will be removed after 15 ignition switch on/off cycles.</P>
Low system voltage, bad battery or battery terminals - If the system recently had a power drop (due to a dead battery or bad alternator), this code will appear. If the battery terminals are bad and the engine was jumped, this code will appear.</P>
Bad connection or wiring - Check the wiring and connections between the battery, power module, and logic module (or SMEC). Check all fusible links and power connectors to the battery. Clean and regrease any corroded connectors with dielectric grease and repair any shorts.</P>
<H3>Diagnostic Method</H3>
<H4>Trigger Parameters</H4>
- Logic module receives power after previously not having power</P>
<H4>Results If Component Fails</H4>
Fault code 12 is stored. The logic module is basically telling you that it has lost power and will not remember any previously stored codes or engine sensor table data. The code will be removed after 15 ignition on/off cycles and the logic module will use default values for all look-up tables as a starting point until it "learns" the attributes of the engine.

There ya go...
