INSPECTION PROCEDURE
1 DRIVING TEST
(a) Start the engine.
(b) Turn the ECT SNOW switch ”OFF” (Normal drive mode).
(c) Confirm vehicle response by driving from a parked position to fully depressing the accelerator pe\
dal.
(d) Turn the ECT SNOW switch ”ON” and perform the same check as (c). Confirm that there is a difference between ECT SNOW switch ”ON” and ”OFF”.
HINT:

Driving test should be done on a paved road (a nonskid road).

Make sure not to use the TRAC system when testing a vehicle equipped wit\
h one.
OK:
There is a difference in acceleration between ”ON” and ”OFF”\
.

2 CHECK HARNESS AND CONNECTOR(PATTERN SELECT SWITCH ASSY NO.1 –
BODY GROUND)
(a) Disconnect the connector of pattern select switch.
(b) Measure the resistance according to the value(s) in the
table below.

DTC P2769 TORQUE CONVERTER CLUTCH SOLENOID
CIRCUIT LOW (SHIFT SOLENOID VALVE SL)
DTC P2770 TORQUE CONVERTER CLUTCH SOLENOID
CIRCUIT HIGH (SHIFT SOLENOID VALVE SL)
CIRCUIT DESCRIPTION
The shift solenoid valve SL is turned ”ON” and ”OFF” by signals from the ECM in order to control the hydraulic
pressure operation, the lock–up relay valve, which then the controls operation of the lock–up clutch.
DTC No.DTC Detection ConditionTrouble Area

Shift solenoid valve SL

ECM
MONITOR DESCRIPTION
Based on the signals from the Throttle Position Sensor, the Airflow Meter and the Crankshaft Position Sen-
sor, the ECM sends a signal to the shift solenoid valve SL to regulate the hydraulic pressure and provide
smoother gearshifts. The shift solenoid valve SL responds to commands from the ECM. The valve controls
the lock–up relay valve to perform the torque–converter lock–up function. If the ECM detects an open or
short circuit for shift solenoid valve SL, it will illuminate the MIL.

PROBLEM SYMPTOMS TABLE
If a normal system code is displayed during the DTC check but the problem still occurs, check the circuits
for each problem symptom in the order given in the table below and proceed \
to the relevant troubleshooting
page.
HINT:
Inspect the ”Fuse” and ”Relay” before confirming the suspected area\
s as shown in the chart below.
Inspect each malfunction circuit in numerical order for the correspondin\
g symptom.
