S TERMINAL CIRCUIT
DescriptionINFOID:0000000003860527
The output voltage of the alternator is controlled by the IC voltage regulator at the “S” terminal detecting the
input voltage.
The “S” terminal circuit detects the battery voltage to adjust the alternator output voltage with the IC voltage
regulator.
Diagnosis ProcedureINFOID:0000000003860528
1.CHECK “S” TERMINAL CONNECTION
1. Turn ignition switch OFF.
2. Check if “S” terminal is clean and tight.
Is the inspection result normal?
YES >> GO TO 2.
NO >> Repair “S” terminal connection. Confirm repair by performing complete Starting/Charging system
test. Refer to Technical Service Bulletin.
2.CHECK “S” TERMINAL CIRCUIT
Check voltage between alternator harness connector and ground.
Is the inspection result normal?
YES >> Refer to CHG-2, "Work Flow".
NO >> Check harness for open between alternator and fuse.

WATER OUTLET AND WATER PIPING
5. Remove CVT fluid charging pipe and CVT fluid level gauge. Refer to TM-332, "Exploded View" (VQ25DE)
or TM-168, "
Exploded View" (VQ35DE).
6. Move CVT control cable aside. Refer to TM-319, "
Exploded View" (VQ25DE) or TM-157, "Exploded View"
(VQ35DE).
7. Remove vacuum pipe (front) mounting bolt from water outlet. Refer to EM-67, "
Exploded View".
8. Remove radiator hose (upper) from water outlet.
9. Remove water hoses and heater hoses.
10. Disconnect harness connectors, and move harness to aside.
11. Remove engine coolant temperature sensor as necessary.
CAUTION:
Be careful not to damage engine coolant temperature sensor.
12. Remove water outlet, heater pipe, water bypass pipe and water connector.
INSTALLATION
Note the following, and install in the reverse order of removal.
 Securely insert each hose, and install clamp at a position where it does not interfere with the pipe bulge.
 When inserting water bypass pipe and heater pipe into water connector, apply neutral detergent to O-ring.
InspectionINFOID:0000000003793187
INSPECTION AFTER INSTALLATION
 Check for leakage of engine coolant using the radiator cap tester adapter (commercial service tool) and the
radiator cap tester (commercial service tool). Refer to CO-8, "
Inspection".
 Start and warm up the engine. Visually check that there is no leakage of engine coolant.

< FUNCTION DIAGNOSIS >[VQ25DE, VQ35DE]
VARIABLE INDUCTION AIR SYSTEM
In the medium speed range, the power valves are closed. Under this condition, the pressure waves of the
exhaust stroke do not disturb the pressure waves of the intake stroke of each opposite bank. Therefore, charg-
ing efficiency is increased together with the effect of the long intake passage.
However, in the high speed range, the power valves are open. Under this condition, the pressure waves of
intake stroke are resonant with those of each opposite bank exhaust stroke. Therefore, charging efficiency is
also increased.
In addition, both valves (valves 1 and 2 for VQ35DE engine and a valve for VQ25DE engine) are opened or
closed in other ranges mentioned above. Thus maximum charging efficiency is obtained for the various driving
conditions.
