DIAGNOSIS
TSB Revision
ACTIVE STABILITY CONTROL SYSTEM (ASC)
35C-171
DTC C2111: Brake Fluid Pressure Sensor Power Supply Circuit (High input)
DTC C2112: Brake Fluid Pressure Sensor Power Supply Circuit (Low input)
CAUTION
• If there is any problem in the CAN bus lines, an incor-
rect diagnostic trouble code may be set. Prior to this
diagnosis, diagnose the CAN bus lines (Refer to
GROUP 54C
− CAN Bus Line Diagnostic Flow
• Whenever ECU is replaced, ensure that the CAN bus
lines are normal.
• When the hydraulic unit (integrated with ASC-ECU) is
replaced, always carry out the calibration of the steer-
ing wheel sensor, the G and yaw rate sensor and brake
fluid pressure sensor (Refer to
and
.
OPERATION
When the brake pedal is depressed, the brake fluid pressure
sensor integrated in the hydraulic unit detects the brake fluid
pressure applied from the master cylinder, converts the pres-
sure value into voltage signal, and outputs it.
.
DTC SET CONDITIONS
This diagnostic trouble code is set when the voltage applied to
the pressure sensor is not within the standard value range.
.
PROBABLE CAUSES
ASC-ECU malfunction
DIAGNOSIS
Required Special Tools:
• MB991958: Scan Tool (M.U.T.-III Sub Assembly)
• MB991824: Vehicle Communication Interface (V.C.I.)
• MB991827: M.U.T.-III USB Cable
• MB991910: M.U.T.-III Main Harness A
STEP 1. Using scan tool MB991958, diagnose the CAN bus
lines.
Use scan tool to diagnose the CAN bus lines.
Q: Is the check result normal?
YES : Go to Step 3.
NO : Repair the CAN bus lines (Refer to GROUP 54C
−
CAN Bus Diagnostics Table
). On
completion, go to Step 2.
STEP 2. DTC recheck after resetting CAN bus lines
Q: Are DTCs C2111 or C2112 set?
YES : Go to Step 3.
NO : The procedure is complete.
