ON-BOARD DIAGNOSTIC [SJ6A-EL]
Detection condition
• TCM detects ATF temperature of less
than -43 °C {-45.4 °F} when engine is
warmed-up and running.
• Turbine speed signal is not input during
vehicle speed signal 12 pulse period
when driving in D range.
• Vehicle speed signal is not input during
turbine speed signal 12 pulse period
when driving in D range.
• TCM detects that shift solenoid A does
not change from off when engine is
running
• TCM detects that shift solenoid A does
not change from on when engine is
running
• TCM detects that shift solenoid B does
not change from off when engine is
running
• TCM detects that shift solenoid B does
not change from on when engine is
running
• TMC detects that shift solenoid C does
not change from off when engine is
running
• TMC detects that shift solenoid C doe
not change from on when engine is
running
• TCM detects that shift solenoid D does
not change from off when engine is
running
• TCM detects that shift solenoid G does
not change from on when engine is
running
• TCM detects 1–2 shift valve
malfunction.
• TCM detects reverse sequence valve
malfunction.
M range switch circuit malfunction
• M range switch remains on for 2 s or
more except in D range.
Up switch or down switch circuit
malfunction
• When all of the following conditions are
met:
— M range switch off.
— Except D range
— Up or down switch remains on for 10
s or more.
• TCM detects short circuit or short to
ground in steering shift switch circuit
when engine is running.
• Voltage of less than 9 V detected at
TCM terminals 1AD when engine is
running.
• Voltage of less than 11 V detected at
TCM terminals 1AD when engine is
running.
