Duramax Trouble Code Requests

P0402 ~ Exhaust Gas Recirculation (EGR) Flow Excessive
P2610 ~ Control Module Ignition Off Timer Performance
DTC P2610 can be set with a loss of battery voltage to the ECM with the ignition ON. The ignition must be in the OFF position before disconnecting the ECM.
If P2610 is set, turn the ignition OFF and then completely disconnect the ECM harness connector from the ECM for approximately 1 minute. Reinstall all of the ECM connectors and then attempt to clear codes with the scan tool.
⇒ If P2610 resets after code clear, replace the ECM
Can you reset your codes? If you can try that and see if the P0402 comes back, otherwise get ahold of John and see about getting the fingerstick replaced.

These are the 2006 LBZ block heater codes in case anyone is interested.
PO116 (coolant temp)
PO181 (fuel temp)
PO700 (trans requested malfuction indicator lamp)
When I got these my CEL would be on steady, I had no cruise control, and the truck wouldn't shift until about 2300 RPM or so. Hope this helps.
