C0168Right Rear ABS Inlet Solenoid Circuit Malfunction
- Generic OBD-II code · Chassis
- Can trigger limp mode
- How the car detects it
- C0168 has no public trace: it is missing from the accessible J2012 tables, from the NHTSA bulletin index and from the manufacturer pages checked, where Saab for instance uses C2485 for the rear right valves. Taken at face value it covers the inlet solenoid of the right rear brake, which isolates that caliper from master cylinder pressure while the module regulates the wheel. Typical findings are a coil with an open winding, a short between coil and housing, or a corroded plug at the valve block. Toyota and Denso patented the self-test that checks each solenoid for these faults and then trips a cut-off relay, while MOTOR documents how the ATE module times test pulses per valve and shuts anti-lock down when one is wrong.
