P07F2 Transmission Range Control Module Communication Circuit

Check engine lightUsually off
EmissionsNot relevant
Drive cycleNot required
Limp modePossible

The transmission range control module is the separate shift-by-wire control unit that reads the selector and drives the range actuator. P07F2 reports a fault in its communication. Mitsubishi's 2022 CVT with electric shift sets it when the module's start-up CAN check fails and blames the module itself; it switches to neutral only if the CVT or the whole system is affected too, and one of its two entries carries no MIL. GM (U18AA, U2409) and Ford (U101F, without MIL) report the same function under their own U codes.

Likely causes

Shift-by-wire module faulty or its software
Communication wire or connector
Weak battery during start-up

Symptoms

  • Shift warning
  • Usually no restriction; neutral if the transmission is affected too
  • U codes in other modules possible
