[SOLVED] Fixing U1205 Code: Battery Monitor Module & Motor Control Module

If you see the engine light on or the service engine soon warning light, it could be due to the automobile fault code: U1205.

This code indicates a problem with the Motor Control Module (MCM) or Battery Condition Monitor (BCM). The cause could be a faulty MCMBCM, an open or shorted harness, or a poor electrical connection. It’s important to visually inspect the wiring harness and connectors for any damage or corrosion.

The repair time for this fault code is 1.0, and it’s crucial to fix the issue to avoid any further damage to your vehicle. To interpret the fault code, check the “Possible Causes” listed above and follow the recommended fix.

If you notice the Engine Light ON (or Service Engine Soon Warning Light), it could be a sign of u1205 fault code.

Here are the symptoms to look out for:

  • The automobile fault code U1205 has the following symptoms: Engine Light ON, Service Engine Soon Warning Light ON.

The automobile fault code u1205 can be caused by a faulty MCMBCM, openshorted harness, or poor electrical connection.

  • The automobile fault code u1205 can be caused by a faulty Motor Control Module (MCM) or Battery Condition Monitor (BCM).
  • It can also be caused by an open or shorted harness in the MCM/BCM circuit.
  • Additionally, a poor electrical connection in the MCM/BCM circuit can also trigger this fault code.

To fix the u1205 automobile fault code, check the possible causes and inspect related wiring harness and connectors for damage.

  • To fix the automobile fault code u1205, first, check the possible causes listed above.
  • Then, visually inspect the related wiring harness and connectors.
  • Look for any 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 U1205 can be diagnosed and fixed within an estimated repair time of 1.0 hour. The cost of repair is influenced by the hourly rate charged by the auto repair shop, which typically ranges between $75 and $150 per hour.

Therefore, the total cost of diagnosing and fixing the U1205 fault code will depend on the hourly rate charged by the auto repair shop and the estimated repair time required to fix the issue.

The u1205 fault code is related to the Integrated Motor Assist-Controller Area Network (IMA-CAN) system in automobiles. This system uses two signal lines, IMACANH and IMACANL, to receive and transmit multiple signals simultaneously tofrom multiple control modules.

The u1205 code is triggered when the Battery Condition Monitor (BCM) module detects a malfunction in the IMA-CAN system. This can happen when the information is not sent from the Motor Control Module (MCM) through the IMA-CAN or when the information sent from the MCM is abnormal.

What are the possible causes of the u1205 automobile fault code?

If your engine light is on and you’re seeing the u1205 fault code, it could be due to a faulty Motor Control Module (MCM) or Battery Condition Monitor (BCM). It’s also possible that the MCM/BCM harness is open or shorted, or that there’s a poor electrical connection in the MCM/BCM circuit. To fix the issue, visually inspect the wiring harness and connectors, and check for damaged components or corroded connector pins.

How can I fix the u1205 automobile fault code?

If you’re experiencing an Engine Light ON or Service Engine Soon Warning Light due to the u1205 fault code, it’s likely caused by a faulty Motor Control Module (MCM) or Battery Condition Monitor (BCM). Check the related wiring harness and connectors for any damage or poor electrical connections. Look for broken, bent, pushed out, or corroded connector’s pins.

What should I visually inspect to troubleshoot the u1205 automobile fault code?

If you’re troubleshooting the u1205 automobile fault code, start by checking for an illuminated Engine Light or Service Engine Soon Warning Light. The cause of this issue could be a faulty Motor Control Module (MCM) or Battery Condition Monitor (BCM), an open or shorted MCM/BCM harness, or a poor electrical connection in the MCM/BCM circuit. To fix the problem, visually inspect the wiring harness and connectors for any damage, and check for broken, bent, pushed out, or corroded connector pins.
