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.

DIAGNOSTIC TROUBLE CODE CHART
HINT:

Using SST 09843 ±18020, connect the terminals Tc and E1, and remove the short pin.

If any abnormality is not found when inspection parts, inspect the ECU.

If a malfunction code is displayed during the DTC check, check the circuit listed for the code. For details
of each code, turn to the page referred to under the ºSee pageº for respective ºDTC No.º in the DTC
chart.

DTC 11, 12 ABS Solenoid Relay Circuit
CIRCUIT DESCRIPTION
This relay supplies power to each ABS solenoid. After the ignition switch is turned ON, if the initial check is
OK, the relay goes on.
DTC No.DTC Detecting ConditionTrouble Area

Condition 1. or 2. continues for 0.2 sec. or more:
1. IG1 terminal voltage of ABS ECU is 9.5 ± 18.5 V, and
when the solenoid relay is ON.*

2. With solenoid relay ON driving, when IG1 terminal of
ABS ECU is less than 9.5 V.*1

*1 Solenoid relay contact OFF condition:
All of solenoid terminal voltage is half of IG1 terminal voltage or less than.
*
2
Solenoid relay contact ON condition:
All of solenoid terminal voltage is half of IG 1 terminal voltage or more.
Fail safe function:
If trouble occurs in the ABS solenoid relay circuit, the ECU cuts off current to the ABS solenoid relay and
prohibits ABS control.
