INSPECTION PROCEDURE
1 Check PNP SW, REVERSE, 2ND and LOW signal.
When using TOYOTA hand−held tester:
PREPARATION:
(a) Connect the TOYOTA hand−held tester to the DLC3.
(b) Turn the ignition switch ON and TOYOTA hand−held tes-
ter main switch ON.
CHECK:
Shift the shift lever to the P, R, N, 2 or L positions, and read the
PNPSW, REVERSE, 2ND and LOW signals on the TOYOTA
hand−held tester.
OK:
Shift positionSignal
P, NPNP SW OFF → ON
RREVERSE OFF → ON
22ND OFF → ON
LLOW OFF → ON
When using TOYOTA hand−held tester:
PREPARATION:
Turn the ignition switch ON.
CHECK:
Measure the voltage between terminals NSW, R, 2, L of the
ECM and body ground when the shift lever is shifted to the fol-
lowing positions.
OK:
*: The voltage will drop slightly due to lighting up of the back up
light.

O/D Cancel Signal Circuit
CIRCUIT DESCRIPTION
While driving uphill with cruise control activated, in order to minimize gear shifting and provide smooth cruis-
ing, O/D may be prohibited temporarily under some conditions.
The cruise control ECU sends O/D cur signals to the ECM as necessary and the ECM cancels O/D shifting
until these signals are discontinued.

CHECK:
Measure the voltage between terminal P of the ECM and body
ground when the pattern select switch is set to the PWR (POW-
ER) position and NORM (NORMAL) position.
OK:

(b) Clear the DTC.
The following actions will erase the DTCs and
freezed frame data.
Operating the OBD II scan tool (complying with SAE
J1978) or TOYOTA hand−held tester to erase the
codes (See the OBD II scan tool’s instruction book
for operating instructions.).
NOTICE:
If the TOYOTA hand−held tester switches the ECM from the
normal mode to the check mode or vice−versa, or if the
ignition switch is turned from ON to ACC or OFF during the
check mode, the DTCs and freezed frame data will be
erased.
(c) Inspect the DLC3.
The vehicle’s ECM uses V.P.W. (Variable Pulse Width) for
communication to comply with SAE J1850. The terminal
arrangement of DLC3 complies with SAE J1962 and
matches the V.P.W. format.

HINT:
If your display shows ”UNABLE TO CONNECT TO VEHICLE”
when you have connected the cable of the OBD II scan tool or
TOYOTA hand−held tester to the DLC3, turned the ignition
switch ON and operated the scan tool, there is a problem on the
vehicle side or tool side.
If communication is normal when the tool is connected to
another vehicle, inspect the DLC3 on the original vehicle.
If communication is still not possible when the tool is con-
nected to another vehicle, the problem is probably in the
tool itself, so consult the Service Department listed in the
tool’s instruction manual.

DTC P0773 Shift Solenoid E Electrical Malfunction
(Shift Solenoid Valve SL)
CIRCUIT DESCRIPTION
The shift solenoid valve SL is turned ON and OFF by signals from the ECM to control the hydraulic pressure
acting on the lock−up relay valve, which then controls operation of the lock−up clutch.
Fail Safe Function:
If the ECM detects a malfunction, it turns the shift solenoid valve SL OFF.
