INSPECTION PROCEDURE
1 Check operation of speedometer.
CHECK:
Drive the vehicle and check if the operation of the speedometer in the combination meter is normal.
HINT:
The vehicle speed sensor is operating normally if the speedometer display is normal.
NG Check speedometer circuit.
OK
2 Check for short in harness and connector between terminal SPD of ECM and
body ground.
PREPARATION:
(a) Remove the glove compartment (See page SF±73).
(b) Disconnect the connector from ECM.
CHECK:
Check continuity between terminal SPD of ECM and body
ground.
OK:
No continuity (1 M W or higher)
NG Repair or replace harness or connector.
OK

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) are 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.
