Hi. So, yesterday I drove over a pothole (really deep one) and afterwards my check engine light went on. Today I took it to AutoZone so I could get a code reading. My check engine code that spit out was the P0106 which is for the MAP sensor, I got that replaced last week and I am not sure why it went back on again? However, even though my ABS light was not on, the code reading also spit out C1611 and C1612. I am taking the car on Monday to get fixed, can I drive it short distances for the time being? I know that driving with a P0106 isn't detrimental for the time being but I am concerned about driving with the C1611/12. Also, if anyone is a mechanic do you think this will be a costly job?

Hi,

I looked at both the P1611 and P1612. The 1611 can be an issue with one of three things, brakes, steering, or even the tire pressure monitoring system.

The 1612 is specific to the CAN communication between the HECU (hydraulic electronic control unit and the PCM, powertrain control module. I suspect something is loose or was damaged between the two.

CAN stands for controller area network. Basically, all the modules/computers are tied together via a few wires and communicate with each other. In this case, the two aforementioned modules can't communicate.

So, here are my thoughts. If there are no leaks, the brake fluid is full, and everything feels stable, you should be fine to drive it. In the worst case, you will have no ABS or traction control. However, the brakes should work like traditional brakes that didn't have those options.

Please let me know if you have questions. Also, pic 1 below shows the three things under the same C1611 code. Pic 2 shows the wiring between the two modules. That is where the problem most likely exists.

Take care,

Joe
