4. With the engine running, check the ESP OFF indicator lamp turns ON and OFF when the ESP OFF
switch turns ON and OFF. If it dose not operate in accordance with the switch, check the ESP OFF switch
and the circuit.
5. Check that the ESP OFF indicator lamp turns OFF after Approx. 2 seconds delay when the ESP OFF
switch turned ON (The ESP/TCS system was not operated). If the ESP OFF indicator lamp does not turn
OFF in 10 seconds from the engine start, perform the self-diagnosis of ESP/TCS/ABS control unit.

Inspection procedure
1.SELF-DIAGNOSIS RESULT CHECK 1
Check the self-diagnosis results.
Are any self-diagnosis result items above indicated?
>> GO TO 2.
2.CHECK THE CONNECTOR
Remove connectors of the wheel speed sensor which is malfunctioning and the ESP/TCS/ABS control unit.
Check whether the deformation of terminal, or incorporate connection of connectors. Then, connect connec-
tors. In addition, check if the wheel speed sensor cable is damaged due to friction.
Does ABS warning lamp is out when driving 30km/h (49MPH) for Approx. One minute?
YES >> Check is completed.
NO >> GO TO 3.

UNIFIED CONTROL METER
lSpeedometer, odo/trip meter, tachometer, fuel gauge and water temperature gauge are controlled totally
by control unit built-in combination meter.
lDigital meter is adopted for odo/trip meter.*
*The record of the odo meter is kept even if the battery cable is disconnected. The record of the trip meter
is erased when the battery cable is disconnected.
lOdo/trip meter segment can be checked in diagnosis mode.
lMeter/gauge can be checked in diagnosis mode.
HOW TO CHANGE THE DISPLAY FOR ODO/TRIP METER
NOTE:
Turn ignition switch to the “ON” position to operate odo/trip meter.
POWER SUPPLY AND GROUND CIRCUIT
Power is supplied at all times
lthrough 10A fuse [No. 28, located in the fuse block (J/B)]
lto combination meter terminal 45.
