DESCRIPTION
Shifting from 1st to 5th is performed in combination with the ON and OFF operation
of the shift solenoid valves SL1, SL2, S1, S2 and SR, which is controlled by the
ECM. If an open or short circuit occurs in one of the shift solenoid valves, the
ECM controls the remaining normal shift solenoid valves to allow the vehicle to
be operated smoothly. In case of an open or short circuit, the ECM stops sending
current to the circuit. For details, refer to the fail-safe chart (See page
).
DTC Code |
DTC Detection Condition |
Trouble Area |
---|---|---|
P0976 |
The ECM detects a short in the solenoid valve S2 circuit 2 times when solenoid valve S2 is operated (1-trip detection logic). |
|
P0977 |
The ECM detects an open in the solenoid valve S2 circuit 2 times when solenoid valve S2 is not operated (1-trip detection logic). |
|
MONITOR DESCRIPTION
These DTCs indicate an open or short in the shift solenoid valve S2 circuit. When there is an open or short circuit in any shift solenoid valve circuit, the ECM detects the problem, illuminates the MIL and stores the DTC. When the shift solenoid valve S2 is on, if its resistance is 8 Ω or less, the ECM determines there is a short in the shift solenoid valve S2 circuit.
When the shift solenoid valve S2 is off, if its resistance is 100 kΩ or higher,
the ECM determines there is an open in the shift solenoid valve S2 circuit (See
page ).
