Crunching The Numbers: U1204 Diagnosis Cost & Complexity
The automobile fault code U1204 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 fixing the U1204 fault code will depend on the hourly rate charged by the auto repair shop and the estimated repair time required to diagnose and fix the issue.
Decoding U1204: Understanding The Cause Of Communication Failure
The u1204 fault code is related to the Integrated Motor Assist (IMA) – Controller Area Network (CAN) system in automobiles. This system uses two signal lines, IMACANH and IMACANL, to receive and transmit multiple signals simultaneously tofrom multiple control modules.
When the information is not sent from the Powertrain Control Module (PCM) through the IMA-CAN or when the information sent from the PCM is abnormal, the Battery Condition Monitor (BCM) module detects a malfunction and a DTC is stored.
FAQ
If your engine light is on and you’re seeing the u1204 fault code, it could be due to a faulty Powertrain Control Module (PCM), an open or shorted PCM harness, poor electrical connection in the PCM circuit, a faulty Battery Condition Monitor (BCM) Module, or a faulty Motor Control Module (MCM). To fix the issue, check the possible causes listed above, visually inspect the related wiring harness and connectors, and look for any damaged components or broken, bent, pushed out, or corroded connector pins.
If you’re experiencing an illuminated Engine Light or Service Engine Soon Warning Light due to the u1204 fault code, there are a few possible causes to consider. These include a faulty Powertrain Control Module (PCM), an open or shorted PCM harness, poor electrical connection in the PCM circuit, a faulty Battery Condition Monitor (BCM) Module, or a faulty Motor Control Module (MCM). To fix the issue, visually inspect the related wiring harness and connectors, checking for damaged components and broken, bent, pushed out, or corroded connector pins.
While a faulty Powertrain Control Module (PCM) is one of the possible causes of the u1204 automobile fault code, it is not the only one.
