C1252
ABS / stability-control fault code, listed for 1 vehicle line from Toyota. What it means on each one, with sources, and when the module is the cause.
What C1252 means
Listed in T-SB-0032-16 for the same internal-leak condition
On: 2004-2009 Toyota Prius (XW20, Gen 2)
Is it the ABS module?
Check the cheap things first: battery voltage and the main fuses for the ABS pump and module, the ground straps, the module connector (corrosion, a pushed-back pin) and, for wheel-speed codes, the sensor and its wiring at each wheel. If those are good and the code returns as soon as it is cleared — or the scan tool cannot talk to the ABS module at all — the module itself is the likely cause, and that is what we repair.

What does C1252 mean on a Toyota Prius (XW20, Gen 2)?
The source we cite for the 2004-2009 Toyota Prius (XW20, Gen 2) lists it as: Listed in T-SB-0032-16 for the same internal-leak condition. That vehicle uses HYBRID brake actuator (high-pressure accumulator + pump, electronically controlled braking) - not a conventional ABS mod. We repair it as part of the Hybrid brake actuator (brake booster with pump) family, quote.
