Lockup control solenoid Valve

- If there is an open or short circuit in the lockup control solenoid valve or harness, diagnostic trouble code No.63 is displayed by the self-diagnosis function and hold mode is canceled.

- If a malfunction occurs in the lockup control solenoid valve, the solenoid valve goes OFF and lockup is canceled.


3-2 timing solenoid Valve

- If there is an open or short circuit in the 3-2 timing solenoid valve or harness, diagnostic trouble code No.64 is displayed by the self-diagnosis function and hold mode is canceled.

- If a malfunction occurs in the 3-2 timing solenoid valve, the solenoid valve goes OFF and lockup is canceled.


Lockup solenoid Valve

- If there is an open or short circuit in the lockup solenoid valve or harness, diagnostic trouble code No.65 is displayed by the self-diagnosis function and hold mode is canceled.

- If a malfunction occurs in the lockup solenoid valve, the solenoid valve goes OFF and lockup is canceled.


Line pressure solenoid Valve

- If there is an open or short circuit in the line pressure solenoid valve or harness, diagnostic trouble code No.66 is displayed by the self-diagnosis function and hold mode is canceled.

- If a malfunction occurs in the line pressure solenoid valve, line pressure is set at maximum to make driving possible.

- If a malfunction occurs in line pressure solenoid valve, lockup is canceled.


Hold Indicator Light

- If there is an open circuit in the hold indicator lamp harness or the bulb is burnt out, the lamp will not illuminate.

- If there is a short circuit in the hold indicator lamp harness, the lamp will remain illuminated.

- If the wiring between the FAT terminal and 1C terminal is open or shorted, diagnostic trouble codes are not displayed on the Self Diagnosis Checker.

- If the wiring between the FAT terminal and 1B terminal is open or shorted, the hold indicator light does not display the service code(s).


Reduce Torque Signal 1

- If there is an open or short in the reduce torque signal 1 circuit, diagnostic trouble code No.57 is displayed by the self-diagnosis function and hold mode is canceled.

- If a malfunction occurs in the reduce torque signal 1, the torque reduction control function is inhibited and line pressure will be high at shifting. Shift shock may be slightly strong.


Reduce Torque Signal 2

- If there is an open or short circuit in the reduce torque signal 2 circuit, diagnostic trouble code No.58 is displayed by the self-diagnosis function and hold mode is canceled.

- If a malfunction occurs in the reduce torque signal 2, the torque reduction control function is inhibited and line pressure will be high at shifting. Shift shock may be slightly strong.


Inhibitor Signal

- If there is an open circuit in the inhibitor signal circuit, the engine speed will be slightly low in P and N ranges.

- If there is a short circuit in the inhibitor signal circuit, the engine speed will be slightly high in R, D, S, and L ranges.
