DTC B1168, Gauge Control Module Lost Communication after replacing the cabin blower motor
Hi everyone,
I'm completely stuck and could use some help. I replaced the cabin blower motor on my 2008 Honda Civic FK3 2.2 i-CTDi and had to unplug the accelerator pedal to do it. I forgot to plug it back in before reconnecting the battery and switching the ignition on. I realized afterward, reconnected the pedal, but now the car is acting up. I can communicate with my scan tool now, but I'm getting DTC B1168, Gauge Control Module Lost Communication with ECM/PCM Engine Messages, and I can't clear it. It comes back immediately. The engine currently won't start, the MIL comes on with ignition, and the fuses I've checked seem fine. I'm planning to check ECM power, grounds, and CAN wiring next, but could powering the car up with the accelerator pedal unplugged have caused this? Has anyone seen B1168 happen from something other than a real ECM comms or power issue? Any advice or common failure points would be greatly appreciated. Thanks.
