TROUBLE DIAGNOSIS
(Note 1): When the standard value is checked using a circuit tester for voltage measurement, the connector terminals should not extend
forcefully.
(Note 2): Check the pressure of the tire in normal condition.
(Note 3): ON/OFF timing of the ABS warning lamp
ON: When the ignition switch is turned ON (before engine start) or a malfunction is detected.
OFF: 2 seconds after the engine started (the system is in normal condition).
(Note 4): ESP OFF indicator lamp ON/OFF timing
ON: When the ignition switch is turned ON (before engine start) or a malfunction is detected, if the ESP OFF switch is ON.
OFF: 2 seconds after the engine started (the system is in normal condition) and ESP OFF switch is OFF.
(Note 5): ON/OFF timing of the SLIP indicator lamp
ON: When the ignition switch is turned ON (before engine start) or a malfunction is detected.
OFF: 2 seconds after the engine started (the system is in normal condition) and the ESP/TCS function is inactive.
Flashing: ESP/TCS function is active during driving.
STANDARDS WITH CONSULT-II
CAUTION:
The displayed item is the data calculated by the control unit, so it may indicate a normal value even if
an output circuit (harness) is open or shorted.
