DIAGNOSTICS AUTOMATIC TRANSMISSION

1996 LAND CRUISER (RM451U)
DTC P0770 Shift Solenoid E Malfunction
(Shift Solenoid Valve SL)
SYSTEM DESCRIPTION
The ECM uses the signals from the throttle position sensor, air −
flow meter and crankshaft position sensor to monitor the en-
gagement condition of the lock −up clutch.
Then the ECM compares the engagement condition of the
lock−up clutch with the lock −up schedule in the ECM memory
to detect mechanical trouble of the shift solenoid valve SL,
valve body and torque converter clutch.
DTC No.DTC Detecting ConditionTrouble Area
P0770
Lock− up does not occur when driving in the lock− up range
(normal driving at 80 km/h [50 mph] ), or lock− up remains ON
in the lock− up OFF range (2 trip detection logic)Shift solenoid valve SL is stuck open or closed
 Valve body blocked up or stuck
 Lock− up clutch
INSPECTION PROCEDURE
1 Check shift solenoid valve SL operation.
PREPARATION:
Remove the shift solenoid valve SL from the valve body.
CHECK:
(a) Applying 490 kPa (5 kgf/cm2, 71 psi) of compressed air,
check that the solenoid valve opens.
(b) When battery voltage is supplied to the shift solenoid
valve, check it does not leak air.
NG Replace shift solenoid valve SL.
OK

9. VISUALLY INSPECT CHARCOAL CANISTER
Look for cracks or damage.
10. INSPECT FOR CLOGGED FILTER AND STUCK VALVE
(a) Using low pressure compressed air (7.26 kPa, 74 gf/cm
2,
1.05 psi), blow into tank pipe and check that air flows with-
out resistance from the other pipes.
(b) While holding drain pipe closed, blow air (1.96 kPa, 20 gf/
cm
2, 0.28 psi) into purge pipe and check that air flow with-
out resistance from tank pipe.
If a problem is found, replace the charcoal canister.
11. CLEAN FILTER IN CANISTER
Clean the filter by blowing 294 kPa (3 kgf/cm
2, 43 psi) of com-
pressed air into tank pipe while holding purge pipe closed.
NOTICE:
Do not attempt to wash the canister.No activated carbon
should come out.
12. REINSTALL CAP TO CHARCOAL CANISTER
13. REINSTALL CHARCOAL CANISTER TO BRACKET Torque: 14 N·m (145 kgf·cm, 10 ft·lbf)
14. REINSTALL CHARCOAL CANISTER WITH BRACKET Torque: 18 N·m (185 kgf·cm, 13 ft·lbf)

16. REMOVE TVV FROM CYLINDER HEAD
(a) Disconnect the 2 vacuum hoses.
(b) Remove the TVV.
17. INSPECT TVV OPERATION
(a) Cool the TVV to below 45° C (113°F) with cool water.
(b) Check that air flows from pipe J to the air filter.
(c) Heat the TVV to above 64° C (147°F) with hot water.
(d) Check that air flows from pipe J to pipe K.
If operation is not as specified, replace the TVV.
18. REINSTALL TVV
(a) Apply adhesive to 2 or 3 threads of the TVV, and install it.
Adhesive:
Part No. 08833 −00070, THREE BOND 1324
or equivalent
Torque: 29 N·m (300 kgf·cm, 22 ft·lbf)
(b) Reconnect 2 vacuum hoses.

22. INSPECT VCV
(a) Apply vacuum above 9.3 kPa (70 mmHg, 2.76 in.Hg) to
pipe S.
(b) Blow air into pipe Y and check that air comes out of pipe Z.
(c) Stop the applied vacuum.
(d) Blow air into pipe Y and check that air does not come out
of pipe Z.
If operation is not as specified, replace the VCV.
23. REINSTALL VCV
24. INSTALL INTAKE MANIFOLD STAY Torque: 36 N·m (360 kgf·cm, 26 ft·lbf)
25. REMOVE INTAKE MANIFOLD STAY
26. REMOVE CHECK VALVE
27. INSPECT CHECK VALVE
(a) Check that air flows from the orange pipe to the black pipe.
(b) Check that air does not flow from the black pipe to the
orange pipe.
If operation is not as specified, replace the check valve.
28. REINSTALL CHECK VALVE
HINT:
Reinstall the check valve with the black pipe facing the VCV
side.
29. INSTALL INTAKE MANIFOLD STAY Torque: 36 N·m (360 kgf·cm, 26 ft·lbf)
