PROBLEM
The existing engine wiring harness can cause a 3511-6 code on certain G3306B AFRC Engines. If the existing CSA harness has a voltage spike, then the 3511-6 code will appear alerting operator that the 24 volt supply to the DC/DC convertor has been turned off therefore sending the engine into "feed back disabled (open loop)" operation instead of "oxygen feed back enabled (closed loop)" mode. |
