●This is an OBD-II self-diagnostic item and not available in TCM self-diagnosis.
●This malfunction will not be detected while the O/D OFF indicator lamp is indicating another self-diagnosis
malfunction.
●This malfunction is detected when the A/T does not shift into second gear position as instructed by the
TCM. This is not caused by electrical malfunction (circuits open or shorted) but by mechanical malfunction
such as control valve sticking, improper solenoid valve operation, etc.
TCM TERMINALS AND REFERENCE VALUE
Remarks: Specification data are reference values.
ON BOARD DIAGNOSTIC LOGIC
This diagnosis monitors actual gear position by checking the torque converter slip ratio calculated by TCM as
follows:
Torque converter slip ratio = A x C/B
A: Output shaft revolution signal from revolution sensor
B: Engine speed signal from ECM
C: Gear ratio determined as gear position which TCM supposes
If the actual gear position is higher than the position (2nd) supposed by TCM, the slip ratio will be more than
normal. In case the ratio exceeds the specified value, TCM judges this diagnosis malfunction.
This malfunction will be caused when shift solenoid valve B is stuck open.

●This malfunction is detected when the A/T does not shift into third gear position as instructed by the TCM.
This is not caused by electrical malfunction (circuits open or shorted) but by mechanical malfunction such
as control valve sticking, improper solenoid valve operation, malfunctioning servo piston or brake band,
etc.

●This is an OBD-II self-diagnostic item and not available in TCM self-diagnosis.
●This malfunction will not be detected while the O/D OFF indicator lamp is indicating another self-diagnosis
malfunction.
●This malfunction is detected when the A/T does not shift into fourth gear position or the torque converter
clutch does not lock up as instructed by the TCM. This is not caused by electrical malfunction (circuits
open or shorted) but by mechanical malfunction such as control valve sticking, improper solenoid valve
operation, malfunctioning oil pump or torque converter clutch, etc.
