ON-BOARD DIAGNOSTIC [SJ6A-EL]
Detection condition
• Feedback current corresponding to
solenoid current command value is
irregular when engine is running.
• Open or short circuit in line pressure
control solenoid signal system (while
TCM monitors solenoid output voltage,
the voltage that differs from the signal
output by CPU in TCM is detected).
• Short circuit in line pressure control
solenoid signal system (while TCM
monitors solenoid output voltage, the
voltage that differs from the signal
output by CPU in TCM is detected).
• Feedback current corresponding to
solenoid current command value is
irregular when engine is running.
• Open or short circuit in shift solenoid F
signal system (while TCM monitors
solenoid output voltage, the voltage
that differs from the signal output by
CPU in TCM is detected).
• Short circuit in shift solenoid F signal
system (while TCM monitors solenoid
output voltage, the voltage that differs
from the signal output by CPU in TCM
is detected).
• Short to ground in shift solenoid A
signal system (while TCM monitors
solenoid output voltage, the voltage
that differs from the signal output by
CPU in TCM is detected).
• Open or short circuit in shift solenoid A
signal system (while TCM monitors
solenoid output voltage, the voltage
that differs from the signal output by
CPU in TCM is detected).
• Short to ground in shift solenoid B
signal system (while TCM monitors
solenoid output voltage, the voltage
that differs from the signal output by
CPU in TCM is detected).
• Open or short circuit in shift solenoid B
signal system (while TCM monitors
solenoid output voltage, the voltage
that differs from the signal output by
CPU in TCM is detected).
• Short to ground in shift solenoid C
signal system (while TCM monitors
solenoid output voltage, the voltage
that differs from the signal output by
CPU in TCM is detected).
• Open or short circuit in shift solenoid C
signal system (while TCM monitors
solenoid output voltage, the voltage
that differs from the signal output by
CPU in TCM is detected).
• Short to ground in shift solenoid D
signal system (while TCM monitors
solenoid output voltage, the voltage
that differs from the signal output by
CPU in TCM is detected).
