U0342Software Incompatibility With Hybrid/EV Battery Interface Control Module I
- Generic OBD-II code · Network
- Matters for the ITP
- Can trigger limp mode
- How the car detects it
- Mitsubishi shows that a replaced monitoring board must first be given its place in the pack. On the 2022 Outlander plug-in hybrid, numbering of the cell monitoring units (CMU) is done at the factory; after a CMU or battery module has been replaced, the workshop runs CMU ID numbering from the battery management unit with the M.U.T.-III tester, never while the battery is charging, and checks that every ID data item reads complete, repeating the routine otherwise. The same manual names the CMU among probable causes of cell temperature faults. Mitsubishi uses no letter codes here, and the ninth position I presupposes a pack with nine boards. U01A8 is I's lost-contact code, U04A9 invalid data.
