Fourth Gear Inhibit Signal (ASC signal)

- If there is an open circuit in the Fourth gear inhibit circuit, there is no input signal from the cruise control unit and acceleration feeling (driving performance) will deteriorate when the vehicle speed drops 8 km/h (5 mph) below the set speed or RESUME/ACCEL switch is operated during cruise control operation.

- If there is a short in the Fourth gear inhibit signal circuit, there is no shift to Fourth gear.

Engine RPM Signal (Ne1 signal)

- If there is no input signal from the engine rpm signal, diagnostic trouble code No.01 is displayed by the self-diagnosis function, and hold mode is canceled.

Barometric Absolute Pressure Sensor

- If there is an open or short circuit in the barometric absolute pressure sensor circuit, the line pressure is not controlled correctly at high altitude and shift shock will be strong.

Torque Reduced Signal/Engine Coolant Temperature Signal

- If there is an open or short in the torque reduced signal circuit/engine coolant temperature signal circuit, diagnostic trouble code No.59 is displayed by the self-diagnosis function but hold mode is normal.

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

- The hold indicator lamp does not flash if there is an open and short circuit in the torque reduced signal/engine coolant temperature signal circuit; however the service code No. is memorized in the powertrain control module (Transaxle), and the service code No. is displayed when TAT terminal is grounded.

TAT Terminal (Data Link Connector)

- If there is an open circuit in the TAT terminal or harness, diagnostic trouble code(s) are not displayed by the self-diagnosis function.

- If there is a short circuit in the TAT terminal or harness, diagnostic trouble code(s) memorized in the powertrain control module (transaxle) are displayed by hold indicator.


1-2 shift solenoid Valve

- If there is an open or short circuit in the 1-2 shift solenoid valve or harness, diagnostic trouble code No.60 is displayed by the self-diagnosis function and hold mode is canceled.

- If a malfunction occurs in the 1-2 shift solenoid valve, the solenoid valve goes OFF and lockup is canceled.

2-3 shift solenoid Valve

- If there is an open or short circuit in the 2-3 shift solenoid valve or harness, diagnostic trouble code No.61 is displayed by the self-diagnosis function and hold mode is canceled.

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

3-4 shift solenoid Valve

- If there is an open or short circuit in the 3-4 shift solenoid valve or harness, diagnostic trouble code No.62 is displayed by the self-diagnosis function and hold mode is canceled.

- If a malfunction occurs in the 3-4 shift solenoid valve, the solenoid valve goes OFF and lockup is canceled.
