Brake Fluid Pressure Sensor Inspection

WARNING: This page is about a different car, the 2007 Mazda MX-5 Miata. However, it is still accessible from the selected car via links, so may be relevant.

Turn the ignition switch off.
Install the SSTs to the master cylinder.
NOTE:
- Install the SST (49 N043 001) to the master cylinder using a commercially available flare nut wrench.
  - Flare nut across flat: 12 mm {0.47 in}
Bleed the air from the SSTs and the brake line. (Bleed air from the SSTs through air bleeding valve A.)

Connect the M-MDS to the DLC-2.
Select the MCYLI P PID.
Start the engine.
Depress the brake pedal, and confirm that the fluid pressure value of the SST (Gauge) and the value shown on the M-MDS are equal.
- If the fluid pressures are different, replace the DSC HU/CM.
