ON-BOARD DIAGNOSTIC [SJ6A-EL]
Detection condition
• Open or short circuit 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).
• Short to ground in shift solenoid E
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 E
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 G
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 G signal
system (while TCM monitors solenoid
output voltage, the voltage that differs
from the signal output by CPU in TCM
is detected).
• TCM detects that TCC control solenoid
does not change from on when engine
is running
• TCM detects that TCC control solenoid
does not change from off when engine
is running
• Feedback current corresponding to
solenoid current command value is
irregular when engine is running.
• Short circuit in TCC control solenoid
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 TCC control
solenoid signal system (while TCM
monitors solenoid output voltage, the
voltage that differs from the signal
output by CPU in TCM is detected).
• Bus off error is detected.
• Communication error is detected
between TCM and PCM.
