Inspection Procedure
NOTE:
When replacing the brake actuator assembly, perform zero point calibration (See CALIBRATION
).
- CHECK CAN COMMUNICATION SYSTEM
- Check if the CAN communication system DTC is output (See
DIAGNOSIS SYSTEM
).
Result
RESULT CHARTResult Proceed to DTC not output A DTC output B
B : INSPECT CAN COMMUNICATION SYSTEM (See HOW TO PROCEED WITH TROUBLESHOOTING )
A: Go to next step
- Check if the CAN communication system DTC is output (See
DIAGNOSIS SYSTEM
).
- INSPECT DLC3
- Turn the ignition switch to ON.
- Measure the voltage according to the value(s) in the table below.
Standard voltage
TESTER CONNECTION SPECIFIED CONDITION CHARTTester Connection Switch Condition Specified Condition F16-13 (TC) - F16-4 (CG) Ignition switch ON 11 to 14 V Result
RESULT CHARTResult Proceed to NG A OK B
B: Go to step 5
A: Go to next step
- CHECK HARNESS AND CONNECTOR (TC of DLC3 - ECM)
- Turn the ignition switch to OFF.
- Disconnect the ECM connector.
- Measure the resistance according to the value(s) in the table below.
Standard resistance
TESTER CONNECTION SPECIFIED CONDITION CHARTTester Connection Condition Specified Condition F16-13 (TC) - A21-27 (TC) Always Below 1 Ω F16-13 (TC) - Body ground Always 10 kΩ or higher
NG: REPAIR OR REPLACE HARNESS OR CONNECTOR
OK: Go to next step
- CHECK HARNESS AND CONNECTOR (CG of DLC3 - BODY GROUND)
- Measure the resistance according to the value(s) in the table below.
Standard resistance
TESTER CONNECTION SPECIFIED CONDITION CHARTTester Connection Condition Specified Condition F16-4 (CG) - Body ground Always Below 1 Ω
NG: REPAIR OR REPLACE HARNESS OR CONNECTOR

OK: Go to next step
- Measure the resistance according to the value(s) in the table below.
- CHECK ECM (TC of DLC3 INPUT)
- Turn the ignition switch to OFF.
- Reconnect the ECM connector.
- Using SST, connect terminals TC and CG of the DLC3.
- Turn the ignition switch to ON.
- Check that the check engine warning light is blinking.
Result
RESULT CHARTResult Proceed to Check engine warning light is blinking A Check engine warning light is not blinking B
B : INSPECT SFI SYSTEM (See HOW TO PROCEED WITH TROUBLESHOOTING )
A : REPLACE BRAKE ACTUATOR ASSEMBLY (See REMOVAL )
