Inspection Procedure
NOTE:
- When replacing the skid control ECU, perform the following operations:
- Initialization of linear solenoid valve and calibration (see INITIALIZATION )
- Yaw rate and acceleration sensor zero point calibration (see CALIBRATION )
- When replacing the brake actuator, perform initialization of the linear solenoid valve and calibration (see INITIALIZATION ).
- CHECK HARNESS AND CONNECTOR (SKID CONTROL ECU - BRAKE ACTUATOR)
- Disconnect the A19 ECU connector.
- Disconnect the A27 actuator connector.
- Measure the resistance according to the value(s) in the table below.
Standard resistance
RESISTANCE SPECIFICATIONTester Connection Condition Specified Condition A19-9 (PCK1) - A27-37 (PCK1) Always Below 1 Ω A19-26 (PAC1) - A27-46 (PAC1) Always Below 1 Ω A19-27 (VCM) - A27-35 (VCM) Always Below 1 Ω A19-28 (E) - A27-45 (E) Always Below 1 Ω A19-9 (PCK1) - Body ground Always 10 kΩ or higher A19-26 (PAC1) - Body ground Always 10 kΩ or higher A19-27 (VCM) - Body ground Always 10 kΩ or higher A19-28 (E) - Body ground Always 10 kΩ or higher
NG: REPAIR OR REPLACE HARNESS OR CONNECTOR
OK: Go to next step
- RECONFIRM DTC
- Clear the DTC (see DTC CHECK / CLEAR ).
- Turn the power switch ON (IG).
- Check if the same DTC is recorded (see DTC CHECK / CLEAR
).
HINT:
Reinstall the sensors, connectors, etc. and restore the vehicle to its prior condition before rechecking for DTCs.
Result
RESULT REFERENCEResult Proceed to DTC (C1365/54) is output A DTC (C1365/54) is not output B
B: USE SIMULATION METHOD TO CHECK (See HOW TO PROCEED WITH TROUBLESHOOTING )
A: Go to next step
- CHECK FREEZE FRAME DATA
- Check the information code from the "FREEZE FRAME DATA" memorized when the DTC (C1365/54) is stored (see FREEZE FRAME DATA
).
Result
RESULT REFERENCEResult Proceed to Sensor power supply voltage trouble code (211) is output A Sensor output value trouble codes (212, 214 and 215) are output B
B: REPLACE BRAKE ACTUATOR (See REMOVAL )
A: REPLACE SKID CONTROL ECU (See REMOVAL )
- Check the information code from the "FREEZE FRAME DATA" memorized when the DTC (C1365/54) is stored (see FREEZE FRAME DATA
).
