If you see the Engine Light ON or Service Engine Soon Warning Light, it could be due to the p1b0c fault code. Here are the symptoms to look out for:

  • The P1B0C fault code in automobiles can cause the following symptoms: Engine Light ON, Service Engine Soon Warning Light ON.

The P1B0C automobile fault code can be caused by various issues, including a faulty drive motor control module and poor electrical connections.

  • The automobile fault code P1B0C can be caused by a faulty Drive Motor 1 Control Module Hybrid/EV Battery.
  • It can also be caused by an open or shorted Drive Motor 1 Control Module Hybrid/EV Battery harness.
  • Additionally, a poor electrical connection in the Drive Motor 1 Control Module Hybrid/EV Battery circuit can also trigger this fault code.

To fix the p1b0c automobile fault code, check the possible causes and inspect the wiring harness and connectors for any damage or corrosion.

  • To fix the automobile fault code p1b0c, first, check the possible causes listed above.
  • Then, visually inspect the related wiring harness and connectors.
  • Look for damaged components and check for broken, bent, pushed out, or corroded connector’s pins.
  • This fix will take an estimated repair time of 1.0 hour.

The automobile fault code P1B0C has an estimated repair time of 1.0 hour.

The cost of fixing this fault code is influenced by the repair time.

Most auto repair shops charge between $75 and $150 per hour for their services.

Therefore, the fixing cost of P1B0C will depend on the hourly rate charged by the repair shop.

It is important to consider these factors when budgeting for the repair of this fault code.

The P1B0C fault code relates to the power inverter module in a hybrid vehicle. It contains two motor control modules that measure hybrid battery high voltage. Loss of isolation between high-voltage circuits and vehicle chassis is tested when high-voltage contactor relays are closed.

Motor control module loss of isolation is detected through two high-impedance resistors and voltage measuring circuitry.

The motor isolation voltage display will indicate voltage that is more or less than actual hybrid battery high voltage when a loss of isolation is present.

What are the possible causes of the P1B0C fault code in an automobile?

If you’re experiencing the P1B0C fault code in your automobile, you may notice that the engine light is on or the service engine soon warning light is illuminated. This fault code is typically caused by a faulty drive motor 1 control module hybrid/EV battery, an open or shorted harness, or a poor electrical connection in the drive motor 1 control module hybrid/EV battery circuit. To fix this issue, it’s important to visually inspect the related wiring harness and connectors, check for damaged components, and look for broken, bent, pushed out, or corroded connector’s pins.
