(A)
(B)
When any malfunction occurs in the items related to the A/T
system, which are described below, the symbol (A) continues
being displayed in the information screen in the multi information
display.
Check if the diagnostic trouble code is set when the symbol (A)
continues being displayed in the information screen in the multi
information display.
NOTE:
When the symbol (B) is displayed in the information
screen in the multi information display, the transmission
fluid temperature is high. (Symbol (B) is turned on when the
fluid temperature is approximately 140°C (284°F)or higher
and turned off automatically when the fluid temperature
drops below approximately 135°C(275°F).)
NOTE:
When transmission fluid becomes a high temperature,
control to lower temperature of transmission fluid acts,
and "D" is displayed of a run with sports mode by a shift
indicator in a multi information display; and normal from
sports mode; shifting is replaced automatically. In
addition, there is the case that does not accept operation
to sports mode. It is control to lower temperature of
transmission fluid, and this phenomenon is not trouble. If
temperature of transmission fluid falls, A/T returns to
normal movement.
ON-BOARD DIAGNOSTICS
The transaxle control module (TCM) monitors its
input/output signals (some signals all the time and
others under specified conditions). When an irregular
signal is initially monitored, the TCM decides that a
malfunction has occurred and records the occurrence
as a diagnostic trouble code. There are 45 diagnostic
items. The diagnostic results can be read with scan
tool. Diagnostic trouble codes are kept in memory by
direct battery feed. The codes are retained in memory
even if the ignition switch is in the "LOCK" (OFF)
position. DTCs are not erased even after the battery
terminals and the TCM connector are disconnected.
In addition, the diagnostic trouble code can also be
erased by scan tool.
NOTE:
If a sensor is disconnected when the ignition switch
is in the "ON" position, a diagnostic trouble code is stored
in memory. In this case, erase the DTC using scan tool.
The 45 diagnostic items are displayed in numeric
order.
