P0DA4 flags a rear inverter voltage that is electrically valid but disagrees with the other voltage readings on the same high-voltage bus. Mitsubishi spells out the check for the 2023 Outlander PHEV: once the power drive unit has at least 8 V, voltage control is off, CAN is healthy and the rear value is available, all three comparisons must fail together, namely capacitor 2 main, capacitor 2 sub and capacitor 1 each differing from the rear inverter reading by at least 100 V, held 0.2 s or longer. Because a single deviating reading is not enough, the rear sensor itself is the prime suspect. The manual first clears higher-priority codes and the rear unit's P0C7A, P0DA5, P0DA6 and P30D1, then replaces the power drive unit. The warning light and MIL come on. The battery-side correlation code is P0DA9.

Likely causes

Rear inverter voltage sensing drifts against the other bus readings
Power drive unit faulty (Mitsubishi final repair step)
Underlying fault in the rear motor control unit (P0C7A, P0DA5, P0DA6, P30D1)
Battery management unit reporting incorrectly

Symptoms

  • Plug-in hybrid system warning and MIL on
  • Rear motor power limited
  • Code returns only after the OBD-II drive cycle
