DescriptionNJAT0287+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 indi-
cator lamp is indicating another self-diagnosis malfunction.
+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.

ON BOARD DIAGNOSTIC LOGICNJAT0287S02This 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 (3rd) supposed
by TCM, the slip ratio will be more than normal. In case the ratio
exceeds the specified value, TCM judges this diagnosis malfunc-
tion.
This malfunction will be caused when shift solenoid valve A is stuck
closed.
