U0589Invalid Data Received From DC/AC Converter Control Module A
- Generic OBD-II code · Network
- How the car detects it
- A DC/AC converter turns the vehicle's DC supply into household-style AC for power outlets in the cabin or truck bed. Ford calls the 7.2 kW Pro Power Onboard unit of the 2021 F-150 PowerBoost direct current/alternating converter module A (DCACA) and fixed a service message there by reprogramming the PCM and the DCACA. GM's PIT6527 for the 2026 Colorado and Canyon shows that the body control module watches the converter of the 120 V outlet at the rear of the centre console; there U0288, lost communication, was set falsely on trucks without that outlet. U0589 is the case where the converter does talk but its data, for example output status, load or temperature, are rejected as implausible. A maker's text for U0589 itself is not available. Outlets may switch off.
