If you notice the Engine Light ON or Service Engine Soon Warning Light, it could be a sign of p1a04 fault code. Here are the symptoms to look out for:

  • The P1A04 fault code in an automobile can cause the following symptoms: Engine Light ON, Service Engine Soon Warning Light ON.

The P1A04 fault code can be caused by a faulty BECM, open or shorted BECM harness, or poor electrical connection.

  • The automobile fault code P1A04 can be caused by a faulty Battery Energy Control Module (BECM).
  • It can also be caused by an open or shorted harness of the Battery Energy Control Module (BECM).
  • Additionally, a poor electrical connection in the circuit of the Battery Energy Control Module (BECM) can also trigger this fault code.

To fix the p1a04 automobile fault code, check the possible causes and inspect related wiring harness and connectors for damage.

  • To fix the automobile fault code P1A04, 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 factors that influence the cost of diagnosing and fixing the automobile fault code P1A04 are: – The estimated repair time is 1.0 hour.

– Auto repair shops usually charge between $75 and $150 per hour. – The cost may vary depending on the location and reputation of the repair shop.

– The cost may also depend on the severity of the issue and the parts that need to be replaced. – It is important to get a detailed estimate from the repair shop before proceeding with the repairs.

The P1A04 fault code is related to the Battery Energy Control Module (BECM). The BECM diagnoses its own systems and detects when a fault condition is present. The BECM communicates diagnostics and system status to the hybrid powertrain control module through serial data.

The P1A04 code indicates a fault in the BECM’s Programming Read Only Memory (PROM). This fault is internal to the BECM and does not involve any external circuits.

The OBDII code is set when the BECM’s PROM is not to factory specifications.

What are the possible causes of the P1A04 automobile fault code?

If you see the engine light on or the service engine soon warning light, it could be due to the P1A04 fault code. This code is usually caused by a faulty Battery Energy Control Module (BECM), an open or shorted BECM harness, or a poor electrical connection in the BECM circuit. To fix this issue, you should visually inspect the related wiring harness and connectors, check for damaged components, and look for broken, bent, pushed out, or corroded connector’s pins.

How can I visually inspect the related wiring harness and connectors to fix the P1A04 fault code?

If you’re experiencing the P1A04 fault code, which is indicated by the Engine Light ON or Service Engine Soon Warning Light, you may have a faulty Battery Energy Control Module (BECM), an open or shorted BECM harness, or a poor electrical connection in the BECM circuit. To fix this issue, you should visually inspect the related wiring harness and connectors. Check for damaged components and look for broken, bent, pushed out, or corroded connector’s pins. This will help you identify any issues and determine the best course of action to take.

What are the signs that the Battery Energy Control Module (BECM) harness is open or shorted, causing the P1A04 fault code?

If the engine light is on or the service engine soon warning light is illuminated, it could be a sign of a faulty Battery Energy Control Module (BECM) or an open or shorted BECM harness. The cause could also be a poor electrical connection in the BECM circuit. To fix this issue, it is recommended 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.
