WARNING: This page is about a different car, the 2006 Toyota 4Runner. However, it is still accessible from the selected car via links, so may be relevant.
NOTE:
When replacing the master cylinder solenoid, perform zero point calibration (See CALIBRATION
).
- INSPECT BATTERY
- Check the battery voltage.
Standard: Voltage: 11 to 14 V
NG: INSPECT CHARGING SYSTEM (See ON-VEHICLE INSPECTION , ON-VEHICLE INSPECTION )
OK: Go to next step
- Check the battery voltage.
- INSPECT FUSE (IGN FUSE)
- Remove the IGN fuse from the driver side J/B.
- Check the IGN fuse.
Standard: Below 1
NG: CHECK FOR SHORT IN ALL HARNESS AND CONNECTOR CONNECTED TO FUSE AND REPLACE FUSE
OK: Go to next step
- INSPECT SKID CONTROL ECU (IG2 TERMINAL VOLTAGE)
- Install the IGN fuse.
- Disconnect the skid control ECU (S29) connector.
- Turn the ignition switch to the ON position.
- Measure the voltage according to the value(s) in TERMINALS VOLTAGE SPECIFICATION TABLE .
Standard:
TERMINALS VOLTAGE SPECIFICATION TABLETester Connection Specified Condition S29-1 (IG2) - Body ground 10 to 14 V
NG: REPAIR OR REPLACE HARNESS OR CONNECTOR (IG2 CIRCUIT)
OK: Go to next step
- INSPECT SKID CONTROL ECU (GND TERMINAL CONTINUITY)
- Disconnect the skid control ECU connector.
- Measure the resistance according to the value (s) in TERMINALS RESISTANCE SPECIFICATION TABLE .
Standard:
TERMINALS RESISTANCE SPECIFICATION TABLETester Connection Specified Condition S28-1 (GND1) - Body ground Below 1 S28-32 (GND2) - Body ground Below 1 S29-4 (GND3) - Body ground Below 1
NG: REPAIR OR REPLACE HARNESS OR CONNECTOR (GND CIRCUIT)
OK: Go to next step
- RECONFIRM DTC
- Clear the DTC (See DTC CHECK/CLEAR ).
- Check if the same DTC is detected (See DTC CHECK/CLEAR ).
HINT:
Reinstall the sensors, connectors, etc. and restore the previous vehicle conditions before rechecking for DTCs.
Result:
RESULT REFERENCEDTC is output A DTC is not output B B: END
A: Go to next step
REPLACE MASTER CYLINDER SOLENOID (See OVERHAUL )
