Service Points
O/D OFF SWITCH
If there is an open or short circuit in the O/D OFF switch or harness, selection to/from O/D OFF mode is not possible.
TRANSAXLE RANGE SWITCH
- If there is an open or short circuit in the transaxle range switch or harness, diagnostic trouble code P0705 is displayed by the on-board diagnostic system, and O/D OFF mode is canceled.
- If a malfunction occurs in the wiring of the transaxle range switch, the powertrain control module cannot determine the range position, and shifting may be abnormal in D, 2, and 1 ranges. There may not be a shift to fourth gear.
THROTTLE POSITION SENSOR
- If there is an open or short circuit in the throttle position sensor or harness, diagnostic trouble code P0120 is displayed by the on-board diagnostic system, and O/D OFF mode is canceled.
- If a malfunction occurs in the throttle position sensor, the powertrain control module judges the throttle opening to be at a constant 4/8 stroke.
CLOSED THROTTLE POSITION SWITCH
- If there is an open circuit in the closed throttle position switch or harness, the powertrain control module does not correct throttle characteristics. In case of misadjustment of throttle position sensor, torque converter clutch operation is not canceled when cruising (closed throttle position) and vehicle jolts when accelerator pedal is depressed or released.
- If there is a short circuit in the closed throttle position switch or harness, the line pressure will be low (does not match throttle characteristics) and the transaxle may slip when shifting.
INPUT/TURBINE SPEED SENSOR
- If there is no input signal from the input/turbine speed sensor, diagnostic trouble code P0715 is displayed by the on-board diagnostic system and O/D OFF mode is canceled.
- If a malfunction occurs in the input/turbine speed sensor, shifting is made based on signals from speedometer.
- If a malfunction occurs in the input/turbine speed sensor and vehicle speedometer sensor at the same time, shift solenoid A, B and C go to OFF, and D and 2 ranges go to third gear position. 1 range goes to first gear position, and torque converter clutch operation is inhibited.
VEHICLE SPEEDOMETER SENSOR
- If there is no input signal from the vehicle speedometer sensor, diagnostic trouble code P0500 is displayed by the on-board diagnostic system and O/D OFF mode is canceled.
- If a malfunction occurs in the vehicle speedometer sensor, shifting is made normal based on signals from input/turbine speed sensor.
BRAKE SWITCH
- If there is an open circuit in the brake switch or harness, torque converter clutch operation is not canceled when brake pedal is pressed.
- If there is a short circuit in the brake switch or harness, torque converter clutch operation and slip torque converter clutch operation is inhibited, but slip torque converter clutch functions when coasting.
TRANSAXLE FLUID TEMPERATURE SENSOR
- If there is an open or short circuit in the transaxle fluid temperature sensor or harness, diagnostic trouble code P0710 is displayed by the on-board diagnostic system but O/D OFF mode operates normally.
- If a malfunction occurs in the transaxle fluid temperature sensor, shift shock will be strong.
- The O/D OFF indicator light does not flash if there is an open and short circuit in the transaxle fluid temperature sensor or harness; however the diagnostic trouble code No. is memorized in the powertrain control module.
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 SPEED INPUT SIGNAL
If there is no input signal from the engine speed input signal, diagnostic trouble code P0335 is displayed by the on-board diagnosis function, and O/D OFF mode is canceled.
BAROMETRIC PRESSURE SENSOR
If there is an open or short circuit in the barometric pressure sensor circuit, the line pressure is not controlled correctly at high altitude and shift shock will be strong.
SHIFT SOLENOID A
- If there is an open or short circuit in the shift solenoid A or harness, diagnostic trouble code P0750 is displayed by the on-board diagnostic system and O/D OFF mode is canceled.
- If a malfunction occurs in the shift solenoid A, the solenoid valve turns OFF and torque converter clutch operation is canceled.
SHIFT SOLENOID B
- If there is an open or short circuit in the shift solenoid B or harness, diagnostic trouble code P0755 is displayed by the on-board diagnostic system and O/D OFF mode is canceled.
- If a malfunction occurs in the shift solenoid B, the solenoid valve turns OFF and torque converter clutch operation is canceled.
SHIFT SOLENOID C
- If there is an open or short circuit in the shift solenoid C or harness, diagnostic trouble code P0760 is displayed by the on-board diagnostic system and O/D OFF mode is canceled.
- If a malfunction occurs in the shift solenoid C, the solenoid valve turns OFF and torque converter clutch operation is canceled.
TORQUE CONVERTER CLUTCH CONTROL SOLENOID VALVE
- If there is an open or short circuit in the torque converter clutch control solenoid valve or harness, diagnostic trouble code P1743 is displayed by the on-board diagnostic system and O/D OFF mode is canceled.
- If a malfunction occurs in the torque converter clutch control solenoid valve, the solenoid valve turns OFF and torque converter clutch operation is canceled.
3-2 TIMING SOLENOID VALVE
- If there is an open or short circuit in the ~2 timing solenoid valve or harness, diagnostic trouble code P1765 is displayed by the on-board diagnostic system and O/D OFF mode is canceled.
- If a malfunction occurs in the 3-2 timing solenoid valve, the solenoid valve turns OFF and torque converter clutch operation is canceled.
TORQUE CONVERTER CLUTCH SOLENOID VALVE
- If there is an open or short circuit in the torque converter clutch solenoid valve or harness, diagnostic trouble code P1744 is displayed by the on-board diagnostic system and O/D OFF mode is canceled.
- If a malfunction occurs in the torque converter clutch solenoid valve, the solenoid valve turns OFF and torque converter clutch operation is canceled.
PRESSURE CONTROL SOLENOID
- If there is an open or short circuit in the pressure control solenoid or harness, diagnostic trouble code P0745 is displayed by the on-board diagnostic system and O/D OFF mode is canceled.
- If a malfunction occurs in the pressure control solenoid, line pressure is set at maximum to make driving possible.
- If a malfunction occurs in pressure control solenoid, torque converter clutch operation is canceled.
O/D OFF INDICATOR LIGHT
- If there is an open circuit in the O/D OFF indicator light harness or the bulb is burnt out, the light will not illuminate.
- If there is a short circuit in the O/D OFF indicator light harness, the light will remain illuminated.
TRANSAXLE RANGE SWITCH
- If fuse burnt out while driving, powertrain control module judges condition as the R position.
- When ignition switch is turned from OFF to ON after fuse burnt out, powertrain control module judges condition as the R position.
