Code C1237

Hello, I'm Danny,

I've attached step-by-step diagnostic instructions below to check first before replacing the HECU. Hope this helps and thanks for using 2CarPros.

Check brake illuminated twice a day on the screen then I should stop the engine and start it again to solve the problem.

Hello again.

Did that solve the problem or does the symptom persist? Thanks again for using 2CarPros.

The problem was solved and then reappear after about 15 miles.

It sounds like the ABS pump is out or the sensor is bad.

C1237 Primary Pressure Sensor-Signal
General Information

Component Location

General Description

There are three pressure sensors in HPU (Hydraulic Power Unit). They each measure high pressure accumulator pressure, booster pressure, pedal simulator pressure. AHB ECU (Electronic Control Unit) uses these measured values to monitor AHB operatoring status and control AHB.
After replacing AHB ECU, pressure sensor calibration and PTS calibration are essential.


Check out the diagrams (below). Please let us know what you find. We are interested to see what it is.

AHB ECU replaced, the problem resolved.
Thanks

Glad to hear !
