Accepted Research Accepted research

These curated research findings are useful for discovery but are not yet treated as verified canonical diagnostics.

P060694Solterra (2023): Unexpected operation of the hybrid/EV powertrain control module processor. Torque-monitoring software may falsely detect the condition.
P0A1B1FSolterra (2023 launch generation): Intermittent fault in the generator control module circuit. An incorrect power-isolation or fuse condition during service may set this code.
P0A1C1FSolterra (2023 launch generation): Intermittent fault in the drive motor B control module circuit. An incorrect power-isolation or fuse condition during service may set this code.
U113B87Solterra (2023 launch generation): An expected message from the charging communication module is not being received. An incorrect power-isolation or fuse condition during service may set this code.
