- Faulty Pressure Sensor in Hydraulic and Electronic Control Unit (HECU)
- Hydraulic and Electronic Control Unit (HECU) harness is open or shorted
- Hydraulic and Electronic Control Unit (HECU) circuit poor electrical connection
How do I fix code C1355 HYUNDAI?
Check the “Possible Causes” listed above. Visually inspect the related wiring harness and connectors. Check for damaged components and look for broken, bent, pushed out, or corroded connector’s pins.
Cost of diagnosing the C1355 HYUNDAI code
The cost of diagnosing the C1355 HYUNDAI code is 1.0 hour of labor. The auto repair labor rates vary by location, your vehicle’s make and model, and even your engine type. Most auto repairs shops charge between $75 and $150 per hour.
Possible Symptoms
- Anti-Lock Brake System (ABS) Warning Light ON
- Engine Light ON (or Service Engine Soon Warning Light)
C1355 HYUNDAI Description
The Pressure Sensor is installed in the Hydraulic and Electronic Control Unit (HECU) the purpose of sensing the driver’s braking intention. This sensor has two circuits to measure the current pressure and one circuit to measure the brake oil’s temperature. The HECU compares two signals of the pressure sensor and if it differs with the normal range, the HECU would judge that the pressure sensor has a fault. The HECU measures the pressure value by the ratio of signal voltage to supply voltage. In a case of Smart Cruise Control (SCC) system applied, the two more pressure sensors are added to measure the brake oil’s pressure of wheel.
