What is this part? (module inside right fender) *Please help!*
Could someone please tell me what that module this is? Also what are the skinny tubes for? Also what is the black cannister to the left?
I'm trying to find out the name of the module because I got beached on a curb on some random parking lot median that I didn't see (short guy and power seat was stuck all the way down) and that module was being crushed between the car and the parking block which broke the plastic bracket that holds the module. When we finally got it off the car wouldn't start then noticed a wide plug that was plugged in the bottom of that module was unplugged so I plugged it back in and everything is back to normal but now I'm getting "Service TC, Service AH, Service ABS" message. Only diagnostic message I get is:
28-TCS
C1242 BPMV Pump Motor Ground Circuit Open
A0-LDCM
U1016 Loss Of Communication with PCM (No SOH Message Received)
U1064 Loss Of Communication with DCM (No SOH Message Received)
U1096 Loss Of Communication with IPC (No SOH Message Received)
U1255 Serial Data Line Malfunction -RFA
Would any of those messages relate to that module I may have damaged?

Here's a pic of what happened...

That module is your PCM, the brains of the car. Codes are consistent with unplugging of the PCM. Are they H history codes? If so, clear them all and see what comes back.

The black box in front of/below the silver PCM is the Throttle Control Module. The canister to the left is the vacuum plenum and all the small tubes running to/from it are vacuum lines. The smooth tube between the plenum and the PCM is a drain tube we like to call an "udder".

Those small VAC. lines are going to the A/C .I would have all the codes reset . From what I see the PCM not hurt just upset it got knock around .. Try that should be Ok ,it might have to relearn some stuff but should in a short time be Ok ..
