What Does U058A Mean?
The control module receiving data from the DC to AC converter control module 'B' has detected invalid or implausible data being transmitted over the vehicle communication network. This indicates a communication error in the high-voltage power conversion system typically found in hybrid and electric vehicles.
Safety Warning
Vehicle may enter reduced power mode or fail to operate. High-voltage system faults require specialized training and safety equipment to diagnose safely.
Common Causes
35%
DC to AC converter control module 'B' internal failure or corrupted software
30%
Damaged or corroded wiring harness between converter module and communication bus
20%
Poor ground connection at converter module or communication network
10%
Receiving control module software calibration issue or fault
5%
CAN bus network fault or termination resistor failure
Diagnostic Steps
1
Step 1: Monitor live data stream from DC to AC converter module 'B' and verify if data parameters are present and updating
2
Step 2: Inspect all connectors and wiring at the DC to AC converter module 'B' for damage, corrosion, or loose connections
3
Step 3: Check voltage supply and ground circuits to the converter control module using wiring diagrams
4
Step 4: Test CAN bus communication integrity between converter module and other network modules using bidirectional scan tool or oscilloscope
5
Step 5: If communication is intact, perform software update on affected modules or replace DC to AC converter control module 'B'
