Inspection Procedure
- INSPECT FUSE (ABS NO.1)
- Remove the ABS No.1 fuse from the engine room R/B.
- Measure the resistance according to the value (s) in the table below.
Standard:
TESTER CONNECTION SPECIFIED CONDITION (1 OF 3)ABS No. 1 fuse Below 1 Ω (Continuity) NG: CHECK FOR SHORT IN ALL HARNESS AND CONNECTOR CONNECTED TO FUSE AND REPLACE FUSE
OK: Go to next step.
- INSPECT SKID CONTROL ECU CONNECTOR (+BS TERMINAL VOLTAGE)
- Disconnect the skid control ECU connector.
- Measure the voltage according to the value (s) in the table below.
Standard:
TESTER CONNECTION SPECIFIED CONDITION (2 OF 3)Tester Connection Condition Specified Condition S1-31 (+BS) - Body ground Always 10 to 14 V NG: REPAIR OR REPLACE HARNESS OR CONNECTOR (+BS CIRCUIT)

- INSPECT SKID CONTROL ECU CONNECTOR (GND TERMINAL CONTINUITY)
- Disconnect the skid control ECU connector.
- Measure the resistance according to the value (s) in the table below.
Standard:
TESTER CONNECTION SPECIFIED CONDITION (3 OF 3)Tester Connection Specified Condition S1-32 (GND1) - Body ground Below 1 Ω NG: REPAIR OR REPLACE HARNESS OR CONNECTOR (GND CIRCUIT)

OK: Go to next step.
- RECONFIRM DTC
HINT:
These codes are detected when a problem is determined in the ABS & TRACTION actuator assy.
The ABS solenoid relay is in the ABS & TRACTION actuator assy.
Therefore, solenoid relay circuit inspection relay unit inspection cannot be performed. Be sure to check if the DTC code is output before replacing the ABS & TRACTION actuator assy.
- Clear the DTCs (see DTC CHECK/CLEAR ).
- Turn the ignition switch to the ON position.
Are the same DTCs recorded?
NG: END
HINT:
These DTCs may be memorized due to a malfunction in the connector terminal.
YES: REPLACE ABS & TRACTION ACTUATOR ASSY (SEE REPLACEMENT )
