C0151Right Front ABS Inlet Solenoid Circuit
- Generic OBD-II code · Chassis
- Can trigger limp mode
- How the car detects it
- C0151 mirrors C0141 on the right side and, like it, is not in the accessible J2012 tables. Saab's 9-3 and 9-5 workshop pages for the Bosch 5.3 TC/ABS and for the 9-5 ESP define it as the right pressure-increase valve, separate from the right front wheel valve code C2455; GM's PIP5094 keyword list carries it, and AA1Car's GM-based table reads Right TCS Solenoid #1. In the diagonal brake layout of those cars the valve feeds pressure into the right front circuit when traction control brakes a spinning wheel. Saab watches the circuit for breaks and shorts continuously and runs the valve test above 6 km/h. Once the code sets, ABS, TCS and ESP stay off, and the brake, ABS and central warning lamps come on.
