About P1035

P1035 is a manufacturer-specific powertrain diagnostic trouble code recorded for Mitsubishi vehicles. It belongs to the P-prefix family of codes, which covers engine, transmission, emissions, or fuel-system faults.

Scanning & clearing: A generic OBD-II scan tool will usually read and clear powertrain (P) codes. For live data, freeze-frame capture, and bi-directional tests you may need a more capable scan tool that supports the vehicle's ECM protocol.

P1035 is a manufacturer-specific code. The same code string on a different make may have a different meaning. Always confirm the code's definition against the vehicle's service information for the specific make and model under test.

Code Information

On Mitsubishi plug in hybrid vehicles such as the Outlander PHEV, the PHEV ECU monitors the 12V control power supply feeding the Rear Motor Control Unit (RMCU), which drives the rear electric motor. DTC P1035 sets when the system is in READY and the RMCU control supply voltage drops below the manufacturer minimum, around 8.0V, for a defined period. This indicates the RMCU is not receiving enough control voltage to operate reliably, usually from a weak 12V battery, a poor supply connection, or a fault in the converter that maintains 12V. Symptoms can include loss of rear motor drive and all whe...
