(9) Disconnect the connector of the transmission
wire.
HINT:
Disconnect the connector only when performing
the D position stall test.
(10)Start the engine.
(11)Firmly depress the brake pedal, shift to the D
position, depress the accelerator pedal all the
way down and check the line pressure while the
stall test is performed.
Specified line pressure:
(12)Turn the ignition switch off.
(13)Remove the SST, install the test plug A.
(14)Remove the test plug B, install the SST and
start engine.
SST 09992-00095 (09992-00231, 09992-
00271)
(15)Connect the transmission wire connector,
depress the brake pedal firmly, shift to the R
position and check that the line pressure while
the engine is idling and during the stall test.
Specified line pressure:
(16)Remove the SST, install the test plug B.
(17)Clear the DTC.

DIAGNOSTIC TROUBLE CODE CHART
If a DTC is displayed during the DTC check, check the parts
listed in the table below and proceed to the page given.
HINT:
• *1: Comes on MIL (Malfunction Indicator Lamp) light up
• *2: "DTC stored" mark means ECM memorizes the
malfunction code if the ECM detects the DTC detection
condition.
• This DTC may be output when the clutch, brake and gear
components etc. inside the automatic transmission are
damaged.
