Mirror of C0555 for the right front wheel: the sensor delivers pulses, yet the ABS module rejects it as the wrong component. Mitsubishi lists its code C1063-4A on the 2023 Outlander PHEV as C0556, with the same rule (fitted at the wrong position, at most 3 s, two trips to MIL plus ASC and ABS lamps). Worth noting from that procedure: a code that is only stored, not active, may simply mean the car was not driven after the last repair, and the ABS unit should not be replaced for it; the check needs about 2 minutes at 50 km/h or more. HELLA notes that powered (active) and self-generating (passive) sensors are often hard to tell apart by eye and that carmakers have mostly fitted active ones since 1998, which makes a mixed-up spare part a realistic cause. Circuit faults on this wheel show up as C0506 or C0034 instead.

Likely causes

Replacement sensor of the wrong type (passive instead of active, other side)
Stored code left over because no test drive followed the repair
ABS control unit fault

Symptoms

  • ABS and stability warning lamps on, MIL on some models
  • No ABS or ESC intervention on slippery roads

Repair estimate
