Do these have frequent electrical issues. I didn't really read that when I did my research....
So what is going on anybody know? I don't know what those codes mean really I guess.
No, electrical gremlins are not frequent unless they are caused by a weak or failing battery. If yours was mine Dustin, I'd put the Tech-2 on it see what kind of condition the battery is in. Your B2555 could be causing the battery to drain below 11 volts which will begin setting off all kinds of codes when the various modules run their various self-tests. Some modules throw codes when below 9 volts.
If you don't drive the truck often or very far the battery is going to wear down and will rarely be fully charged, this is where a battery tender comes in handy to 1, keep the truck charged and 2 to recondition the battery to like new status.
From the shop manual:
DTC B2555
DTC Descriptors
DTC B2555 01
- Passenger Compartment Lamp Control Circuit Short to Battery
DTC B2555 02
- Passenger Compartment Lamp Control Circuit Short to Ground
Diagnostic Fault Information
Circuit/System Description
When the body control module (BCM) signals for courtesy lamp operation, a message is sent over the GMLAN serial data circuit to the driver door and passenger door switches. The driver door switch and passenger door switch the applies battery voltage to the left and right courtesy lamp control circuits illuminating the door courtesy lamps. The driver door and passenger door switches also provide ground to the lamps.
Conditions for Running the DTC
- Battery voltage must be between 9-16 volts.
- A message is sent from the BCM over the GM LAN serial data circuit to the driver door and passenger door switches to active the door courtesy lamps.
Conditions for Setting the DTC
B2555 01
This DTC will set when the driver or passenger door switch detects a short to voltage in the courtesy lamp control circuit.
B2555 02
This DTC will set when the driver or passenger door switch detects a short to ground in the courtesy lamp control circuit.
Action Taken When the DTC Sets
B2555 01
When this DTC is present, the door courtesy lamps will remain illuminated.
B2555 02
When this DTC is present, the door courtesy lamps will be inoperative.
Conditions for Clearing the DTC
- The condition responsible for setting the DTC no longer exists.
- A scan tool CLEAR DTCs command is issued for that switch module.
- A history DTC will clear once 100 consecutive malfunction-free ignition cycles have occurred.
Circuit/System Testing
- Disconnect the X2 harness connector at the inoperative door module.
- Verify that a test lamp illuminates between the ground circuit terminal 15 and B+.
¤ If the test lamp does not illuminate, test the ground circuit for an open/high resistance. If the circuit tests normal replace the affected door module.
- Connect a test lamp between the control circuit terminal 10 and the ground circuit terminal 15.
- Command the Puddle/Courtesy Lamp ON and OFF with a scan tool. The test lamp should turn ON and OFF when changing between the commanded states.
¤ If the test lamp is always ON, test the control circuit for a short to voltage. If the circuit tests normal, replace the inoperative door module.
¤ If the test lamp is always OFF, test the control circuit for a short to ground or an open/high resistance. If the circuit tests normal, replace the inoperative door module.
- If all circuits test normal, test or replace the courtesy lamp bulb.
Short answer, might need a new light bulb.
