INSPECTION PROCEDURE

PROCEDURE

1. INSPECT ECU-IG NO. 2 FUSE
(a) Remove the ECU-IG NO. 2 fuse from the instrument panel J/B.





(b) Check continuity of the ECU-IG NO. 2 fuse.
Standard resistance:






NG -- REPLACE ECU-IG NO. 2 FUSE
OK -- Continue to next step.
2. CHECK BATTERY
(a) Check the battery voltage.
Standard voltage:
11 to 14 V
NG -- CHECK OR REPLACE CHARGING SYSTEM OR BATTERY
OK -- Continue to next step.
3. INSPECT SKID CONTROL ECU TERMINAL VOLTAGE (IG1 TERMINAL)
(a) WHEN USING INTELLIGENT TESTER:
(1) Connect the intelligent tester to the DLC3.
(2) Start the engine.
(3) Select the Data List mode on the intelligent tester .

ABS / VSC:





(4) Check that the voltage output from the ECU displayed on the intelligent tester.
OK:
"Normal" is displayed.
(b) WHEN NOT USING INTELLIGENT TESTER:
(1) Disconnect the skid control ECU connector.
(2) Turn the ignition switch to the ON position.





(3) Measure the voltage according to the value(s) in the table below.
Standard voltage:





NOTE: When replacing the brake actuator assembly, perform zero point calibration. Calibration

NG -- INSPECT SKID CONTROL ECU CONNECTOR (GND TERMINAL CONTINUITY)
OK -- REPLACE BRAKE ACTUATOR ASSEMBLY
4. INSPECT SKID CONTROL ECU CONNECTOR (GND TERMINAL CONTINUITY)
(a) Disconnect the skid control ECU connector.





(b) Measure the resistance according to the value(s) in the table below.
Standard resistance:






NG -- REPAIR OR REPLACE HARNESS OR CONNECTOR (GND TERMINAL - BODY GROUND)
OK -- CHECK HARNESS AND CONNECTOR
