It isn't designed to delete the cooler, but it is designed to block the EGR. People are getting the code when they simply block the EGR (not the full delete). Edge customer service even recommends pulling the butterfly when blocking the EGR. Technically, if you reinstall the cooler and simply block the EGR, the edge should work fine but the P245A code still pops up on cold days. The info below explains why temp plays a role.
A forum member, RegenerationComplete, posted the following info about the P245A code (the part I placed in bold seems to explain the problem, which I sent to edge):
P245A-EGR COOLER BYPASS CONTROL CIRCUIT /OPEN
Theory of Operation
The Exhaust Gas Recirculation (EGR) Cooler Bypass Valve is used to redirect the EGR gases around the cooler when the engine is in an active regeneration mode. This is to prevent EGR cooler fouling. The EGR Cooler Bypass Valve is a smart device which communicates it's status to the Engine Control Module (ECM). At key on the ECM drives the signal line low and then high and monitors the correct status response from the EGR Cooler Bypass Valve. Throughout engine operation the ECM sends commands to the EGR Cooler Bypass Valve over the signal circuit. EGR Cooler Bypass Valve status line voltage should be within 5-8 volts. When a fault occurs the EGR Cooler Bypass valve will send a signal between 1.0 and 1.7 volts on the status line to the ECM. The ECM also monitors exhaust gas recirculation temperature Ito determine if the EGR Cooler Bypass Valve was in bypass mode incorrectly. The ECM will light a MIL lamp immediately after this diagnostic runs and fails. The ECM will turn off the MIL lamp after the diagnostic passes in four consecutive drive cycles.· When Monitored:
· Set Condition:
Voltage detected at status line is between 1.0 volt and 1.7 volts for more than 150 seconds consecutively.
Call edge back and tell them you would be willing to reinstall the cooler and just block the EGR, but people are still getting the P245A code.
