SC723-71 B Shift Motor Error
When the shift HP sensor was not turned off while predetermined seconds
applied to the shift motor with the HP sensor turned on.
When shift HP sensor was not turned on while predetermined seconds
applied to the shift motor with the HP sensor turned off.
The STM driver error detection is started after reset, and predetermined
seconds error signal is detected.
This SC will be issued when the above phenomenon repeated 2 times.
• Shift Motor failure
• Connector disconnected
• Shift Motor overload
• Shift HP sensor error
• Harness short-circuit
• Circuit board failure
• Excess current
• Abnormal temperature
Check if the SC occurs by opening/closing covers, and input/output
check. If the SC occurs again, do the following steps. Check if the SC
reoccurs by cycling the power after each step.
• The target parts are the motor and related HP sensor that SC
occurred.
1. Check if the connector of the target part is connected securely.
Reconnect the connector if it is disconnected, or loose.
2. Check the harness for the target part. Replace the harness if it is
disconnected, or damaged.
3. Check if the motor runs, sensors turn OFF/ON, has no overloads,
and is properly driven. Replace the parts if there are any defects.
4. Check if there are any signs of a short circuit. Replace the parts if
there are any defects.
