Check the self-diagnosis results.
Is the above displayed in the self-diagnosis display items?
YES >> GO TO 2.
NO >> Inspection End.
2.CONNECTOR INSPECTION
1. Disconnect the ABS actuator and el ectric unit (control unit) and brake fluid level switch connectors.
2. Check the terminals for deformation, disconnection, looseness or damage.
OK or NG
OK >> GO TO 3.
NG >> Repair or replace as necessary.
3.CHECK TRANSMISSION RANGE SWITCH
Perform transmission range switch inspection. Refer to AT-94, "
Component Inspection" (with A/T) or CVT-65,
"Component Inspection" (with CVT).
Is the inspection result normal?
YES >> Replace ABS actuator and electr ic unit (control unit). Refer to BRC-89, "Removal and Installa-
tion".
NO >> Repair or replace malfunctioning components.

• Warm up engine thoroughly to make sure there is no leakage of fuel, exhaust gas, or any oils/fluids including
engine oil and engine coolant.
• Bleed air from passages in lines and hoses, such as in cooling system.
• After cooling down engine, again check oil/fluid levels including engine oil and engine coolant. Refill to spec-
ified level, if necessary.

THERMOSTAT
INSTALLATION
Installation is in the reverse order of removal.
• Use the following procedure to install the thermostat.
- Install thermostat making sure rubber ring (1) groove fits securely
to thermostat flange (A).
CAUTION:
Replace the rubber ring with a new one.
- Install thermostat (1) into the thermostat housing (2) with jiggle valve (A) facing upwards.
• Use the following procedure to install the thermostat housing.
- Securely insert the rubber ring into the mating groove of thermostat housing and install it. CAUTION:
Replace the rubber ring with a new one.
- Install the thermostat housing to the cylinder block without displacing the gasket from the gasket position.

INSPECTION AFTER INSTALLATION
• Before starting engine, check oil/fluid levels incl uding engine coolant and engine oil. If less than required
quantity, fill to the specified level. Refer to MA-14, "
Fluids and Lubricants".
• Use procedure below to check for fuel leakage.
• Turn ignition switch ON (with engine stopped). With fuel pressure applied to fuel piping, check for fuel leak-
age at connection points.
• Start engine. With engine speed increased, che ck again for fuel leakage at connection points.
• Run engine to check for unusual noise and vibration.
• Warm up engine thoroughly to make sure there is no leakage of fuel, exhaust gas, or any oils/fluids including engine oil and engine coolant.
• Bleed air from passages in lines and hoses, such as in cooling system.
• After cooling down engine, again check oil/fluid levels including engine oil and engine coolant. Refill to spec- ified level, if necessary.
