PART AND SYSTEM NAME LIST
This reference list indicates the part names used in this article along with their definitions.
PART AND SYSTEM REFERENCE TABLE
malfunctions per driving cycle. "Once per driving
cycle" means that the ECM detects malfunction
only one time during a single driving cycle.
"Continuous" means that the ECM detects
malfunction every time when enabling condition is
met.
DurationThe minimum time that the ECM must sense a
continuous deviation in the monitored value(s)
before setting a DTC. This timing begins after the
"typical enabling conditions" are met.
Malfunction thresholdsBeyond this value, the ECM will conclude that
there is a malfunction and set a DTC.
MIL operationMIL illumination timing after a defect is detected.
"Immediately" means that the ECM illuminates
MIL the instant the ECM determines that there is a
malfunction. "2 driving cycle" means that the ECM
illuminates MIL if the same malfunction is detected
again in the 2nd driving cycle.
Component operating rangeNormal operation range of sensors and solenoids
under normal driving conditions. Use these ranges
as a reference. They cannot be used to judge if a
sensor or solenoid is defective or not.

HINT:
According to the DATA LIST displayed by the hand-held tester, you can read the value of the switch, sensor,
actuator and so on without parts removal. Reading the DATA LIST as the first step of troubleshooting is one
method to shorten labor time.
a. Warm up the engine.
b. Turn the ignition switch off.
c. Connect the hand-held tester together with the CAN VIM (controller area network vehicle interface
module) to the DLC3.
d. Turn the ignition switch to the ON position.
e. Push the "ON" button of the hand-held tester.
f. Select the item "DIAGNOSIS/ENHANCED OBD II/DATA LIST".
g. According to the display on tester, read the "DATA LIST".

The ECM commands gear shifts by turning the shift solenoid valves "ON/OFF" and switching oil pressure to
the valves in the valve body.
The ECM calculates the "actual" transmission gear by comparing the signals from the input speed sensor (NT)
and the output speed sensor (SP2). The ECM can detect many mechanical problems in the shift solenoids, valve
body, and the transmission clutches, brakes, and gears. If the ECM detects that the actual gear position and the
commanded gear position are different, it will illuminate the MIL and store the DTC.
