DescriptionNJAT0283+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
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.

ON BOARD DIAGNOSTIC LOGICNJAT0283S02This 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) sup-
posed by TCM, the slip ratio will be more than normal. In case the
ratio exceeds the specified value, TCM judges this diagnosis mal-
function.
This malfunction will be caused when shift solenoid valve B is stuck
open.
