P Output Speed Sensor (Secondary Speed Sensor)
The shift pattern is changed in accordance with the throttle position when an unexpected signal is sent from
the output speed sensor (secondary speed sensor) to the TCM. The sport mode is inhibited, and the transaxle
is put in “D”.
Input Speed Sensor (Primary Speed Sensor)
The shift pattern is changed in accordance with the throttle position and secondary speed (vehicle speed)
when an unexpected signal is sent from the input speed sensor (primary speed sensor) to the TCM. The sport
mode is inhibited, and the transaxle is put in “D”.
PNP Switch
If an unexpected signal is sent from the PNP switch to the TCM, the transaxle is put in “D”.
CVT Fluid Temperature Sensor
If an unexpected signal is sent from the CVT fluid temperature sensor to the TCM, the gear ratio in use before
receiving the unexpected signal is maintained or the gear ratio is controlled to keep engine speed under 5,000
rpm.
Transmission Fluid Pressure Sensor A (Secondary Pressure Sensor)
 If an unexpected signal is sent from the transmission fluid pressure sensor A (secondary pressure sensor) to
the TCM, the secondary pressure feedback control is stopped and the offset value obtained before the non-
standard condition occurs is used to control line pressure.
 If transmission fluid pressure sensor A (secondary pressure sensor) error signal is inputted to the TCM, sec-
ondary pressure feedback control stops, but line pressure is controlled normally.
Pressure Control Solenoid A (Line Pressure Solenoid Valve)
If an unexpected signal is sent from the solenoid valve to the TCM, the pressure control solenoid A (line pres-
sure solenoid valve) is turned OFF to achieve the maximum fluid pressure.
Pressure Control Solenoid B (Secondary Pressure Solenoid Valve)
If an unexpected signal is sent from the solenoid valve to the TCM, the pressure control solenoid B (secondary
pressure solenoid valve) is turned OFF to achieve the maximum fluid pressure.
Torque Converter Clutch Solenoid Valve
If an unexpected signal is sent from the solenoid valve to the TCM, the torque converter clutch solenoid valve
is turned OFF to cancel the lock-up.
Ste p M oto r
If an unexpected signal is sent from the step motor to the TCM, the step motor coil phases “A” through “D” are
all turned OFF to hold the gear ratio used just before the non-standard condition occurred.
CVT Lock-up Select Solenoid Valve
If an unexpected signal is sent from the solenoid valve to the TCM, the CVT lock-up select solenoid valve is
turned OFF to cancel the lock-up.
TCM Power Supply (Memory Back-up)
Transaxle assembly is protected by limiting the engine torque when the memory back-up power supply (for
controlling) from the battery is not supplied to the TCM. Normal status is restored when turning the ignition
switch OFF to ON after the normal power supply.
DTC Inspection Priority ChartINFOID:0000000003849062
If some DTCs are displayed at the same time, perform inspections one by one based on the following priority
chart.
NOTE:
If DTC “U1000 CAN COMM CIRCUIT” is indicated with other DTCs, start from a diagnosis for “DTC
