I have a problem with my Chevrolet Colerado. It is showing me the code P262B. How do I solve it?

The P262B code means the ECM (engine control module) didn’t shut down the way it’s supposed to after the truck is turned off. Basically, something is keeping the computer awake when it should power down.
Here’s what to check:
-
Aftermarket accessories – If you’ve added things like remote start, alarm, stereo, dash cam, or anything that taps into ignition or battery power, it could be keeping the module alive.
-
Faulty relay or module – Sometimes a stuck relay (especially the ECM or fuel pump relay) keeps power flowing after shutdown. Other times, a control module like the BCM or OnStar module doesn’t go to sleep.
-
Battery or ground issues – Weak battery voltage or poor grounding can confuse the shutdown timing logic.
Try a full battery disconnect for 10 minutes to force all modules to reset. If the code comes back, scan for other related codes (especially body or communication codes) and check for any device or circuit that stays powered longer than it should after key-off.
Let me know if anything was recently installed or changed—I can help narrow it down.
