This code indicates that a control module, typically the main powertrain or hybrid controller, is receiving corrupted, implausible, or nonsensical data from the Drive Motor Control Module. It is a network communication code specific to hybrid and electric vehicles, meaning the motor controller is failing to broadcast valid signals over the vehicle's data bus.
The sending module itself has an internal hardware failure, causing it to process data incorrectly and transmit invalid parameters over the network.
Corroded, chafed, or loose network wiring causes electrical interference or signal drops, corrupting the data packets transmitted between modules.
Low voltage from a poor ground or failing power feed causes the module to reboot or operate erratically, resulting in garbage data output.
A previous module replacement or software update mismatch causes the sending and receiving modules to speak different data protocols or use different parameter scales.
The receiving module has an internal fault that prevents it from correctly interpreting valid data, though this is a rare occurrence.
No, it is generally unsafe. Because the main computer cannot trust the data from the drive motor controller, the vehicle may unexpectedly enter limp mode, disable electric propulsion, or stall, which is hazardous in traffic.
No, this is a communication error, not a high-voltage battery fault. While the battery system is closely integrated with the motor controller, this code specifically means the data network signal is corrupted or missing.
Usually not. Drivers are frequently told to replace the receiving PCM or ECM, but this is almost always incorrect. The fault lies with the Drive Motor Control Module, its power/ground, or the wiring between them; the receiving PCM is rarely the cause.
Yes. If the 12V system voltage drops too low, the Drive Motor Control Module cannot power its processors correctly, resulting in it transmitting invalid data over the network before it fully shuts down.
