2 CHECK BATTERY
(a) Check the positive battery voltage.
Standard voltage: 11 to 14 V


3 INSPECT SKID CONTROL ECU (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 condition 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.
