1986 TOYOTA SUPRA oil change

CIRCUIT DESCRIPTION
Camshaft position sensors (G1 and G2 signals) are mounted on the intake side of the cylinder head
and the crankshaft position sensor (NE signal) is mounted on the oil pump body. These sensors consist
of a timing rotor and pick up coil.
The G1, G2 timing rotors have 1 tooth each on their outer circumference and are mounted on the intake
camshaft.
When the intake camshaft rotates, the protrusion on the timing rotors and the air gap on the pick up
coil change, causing fluctions in the magnetic field and generating an electromotive force in the pick
up coil.
The NE timing rotor has 12 teeth and is mounted on the crankshaft. The NE signal sensor generates
12 NE signals per engine revolution. The ECM detects the standard crankshaft angle based on the G1,
G2 signals, and the actual crankshaft angle and the engine speed by the NE signals.

3. REFILL WITH ENGINE OIL
(a) To wipe off oil that has dripped onto the engine under cover,
remove the 4 screws and bend the under cover downward.
NOTICE:
wTo avoid damaging the silencer, do not bend the engine
under cover more than 150 mm.
wIf oil gets on the silencer, wipe it off with a dry rag.
(b) Clean and install the oil drain plug with a new gasket.
Torque: 38 NVm (375 kgfVcm, 27 ftVlbf)
(c) Fill with fresh engine oil.

WHEN THE IGNITION SW IS TURNED ON, CURRENT FLOWS TO TERMINAL 2 OF THE WASHER MOTOR, TERMINAL 1 OF THE REAR WIPER
MOTOR AND RELAY THROUGH THE WIPER FUSE.
1.REAR WIPER NORMAL OPERATIONWITH THE IGNITION SW TURNED ON AND THE REAR WIPER AND WASHER SW TURNED ON, THE CURRENT FLOWING TO TERMINAL 1 OF
THE REAR WIPER RELAY FLOWS TO TERMINAL 3 OF THE RELAY " TERMINAL 1 OF THE REAR WIPER AND WASHER SW " TERMINAL 16 "
TO GROUND. THUS, THE RELAY COIL IS ACTIVATED AND THE CURRENT TO TERMINAL 1 OF THE REALY FLOWS TO TERMINAL LM "
TERMINAL LM OF THE REAR WIPER MOTOR " MOTOR " TO GROUND AND CAUSES THE MOTOR TO OPERATE THE WIPER.
2.REAR WIPER INTERMITTENT OPERATIONWHEN THE IGNITION SW IS ON AND THE REAR WIPER AND WASHER SW IS TURNED TO INT POSITION, CURRENT FLOWING TO TERMINAL 1
OF THE REAR WIPER MOTOR AND RELAY FLOWS TO TERMINAL 2 OF THE RELAY " TERMINAL 10 OF THE REAR WIPER AND WASHER SW
" TERMINAL 16 " GROUND.
THIS CAUSES THE MOTOR TO OPERATE (THE POINT CHANGES) AND THE INTERMITTENT CIRCUIT OF THE RELAY OPERATES.
INTERMITTENT OPERATION OF THE CIRCUIT IS CONTROLLED BY THE CHANGING AND DISCHARGING OF THE CONDENSER INSTALLED
INSIDE THE RELAY.
3.WASHER OPERATIONWITH THE IGNITION SW TURNED ON AND THE REAR WIPER AND WASHER SW TURNED TO ON POSITION, WHEN THE WIPER SW IS TURNED
FURTHER, THE CURRENT FLOWING TO TERMINAL 2 OF THE WASHER MOTOR FLOWS TO TERMINAL 3 OF THE MOTOR " TERMINAL 2 OF
THE REAR WIPER AND WASHER SW " TERMINAL 16 " TO GROUND, SO THAT THE WASHER MOTOR ROTATES AND THE WINDOW WASHER
EJECTS THE SPRAY, ONLY WHILE THE SWITCH IS FULLY TURNED.
WHEN THE WIPER SW IS OFF AND THEN TURNED TO WASHER ON (WIPER OFF SIDE), ONLY THE WASHER OPERATES.
