INSPECTION PROCEDURE
HINT:
This diagnostic chart is based on the premise that the engine is cranked normally. If the engine is not
cranked, proceed to the problem symptoms table on page DI±221.
TOYOTA hand±held tester
1 Connect TOYOTA hand±held tester, and check STA signal.
PREPARATION:
(a) Connect the TOYOTA hand±held tester to the DLC3.
(b) Turn the ignition switch ON and push the TOYOTA hand±held tester main switch ON.
CHECK:
Read STA signal on the TOYOTA hand±held tester while starter operates.
OK:
Ignition switch positionONSTART
STA signalOFFON
OK Proceed to next circuit inspection shown on
problem symptom table (See page DI±221).
NG
2 Check for open in harness and connector between ECM and starter relay
(See page IN±31).
NG Repair or replace or connector.
OK
Check and replace ECM (See page IN±31).

± DIAGNOSTICSAUTOMATIC TRANSAXLE (A140E)
625 Author: Date:

The diagnosis system operates in normal mode
during normal vehicle use, and also has a check
mode for technicians to simulate malfunction symp-
toms and perform troubleshooting. Most DTCs use
2 trip detection logic(*) to prevent erroneous detec-
tion. By switching the ECM to check mode when
troubleshooting, the technician can cause the MIL
to light up and for a malfunction that is only detected
once or momentarily.
(TOYOTA hand±held tester) (See page DI±401)

*2 trip detection logic:
When a logic malfunction is first detected, the mal-
function is temporarily stored in the ECM memory.
If the same malfunction is detected again during the
2nd test drive, this 2nd detection causes the MIL to
light up.
(b) 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 ºUNABLE TO CONNECT TO VEHICLEº
when you have connected the cable of OBD II scan tool or TOY-
OTA hand±held tester to 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 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.
DTC No.DTC Detecting ConditionTrouble Area
P0773
Either (a) or (b) is detected for 1 time.(2 trip detection logic)
(a) Solenoid resistance is 8 W or less short circuit when sole-
noid is energized.
(b) Solenoid resistance is 100 kW or more open circuit when
solenoid is not energized.
