DTC 61 PRESS SEN CIRCUITNKS003FB
1. CHECK CONNECTOR BRAKE PRESSURE SENSOR AND ICC UNIT
1. Turn ignition switch OFF.
2. Disconnect brake pressure sensor connector and ICC unit connector, and connect them securely again.
3. Erase DTC and perform ICC system running test. Then perform self-diagnosis of ICC system again.
Is malfunction indicated?
YES >> GO TO 2.
NO >> Poor connector connection
1. Check connector. (Check connector housing for disconnected, loose, bent, and collapsed ter- minals. If any malfunction is detected, repair applicable part.)
2. Erase DTC and perform ICC system running test. Then perform self-diagnosis of ICC system again.
2. CHECK HARNESS BETWEEN BRAKE PRESSURE SENSOR AND ICC UNIT
1. Turn ignition switch OFF.
2. Disconnect ICC unit connector and brake pressure sensor con- nector.
3. Check continuity between brake pressure sensor harness con- nector and ICC unit harness connector.
4. Check continuity between ICC unit harness connector and ground.

TCM FunctionNCS001AZ
The function of the TCM is to:
Receive input signals sent from various switches and sensors.
Determine required line pressure, shifting point, lock-up operation, and engine brake operation.
Send required output signals to the respective solenoids.
CONTROL SYSTEM OUTLINE
The automatic transmission senses vehicle operating conditions through various sensors or signals. It always
controls the optimum shift position and reduces shifting and lock-up shocks.

CAN CommunicationNCS001B0
SYSTEM DESCRIPTION
CAN (Controller Area Network) is a serial communication line for real time application. It is an on-vehicle mul-
tiplex communication line with high data communication speed and excellent error detection ability. Many elec-
tronic control units are equipped onto a vehicle, and each control unit shares information and links with other
control units during operation (not independent). In CAN communication, control units are connected with 2
communication lines (CAN-H line, CAN-L line) allowing a high rate of information transmission with less wiring.
Each control unit transmits/receives data but selectively reads required data only. For details, refer to LAN-32,
"CAN Communication Unit" .
Input/Output Signal of TCMNCS001B1
*1: Spare for vehicle speed sensor·A/T (revolution sensor)
*2: Spare for accelerator pedal position signal
*3: If these input and output signals are different, the TCM triggers the fail-safe function.
*4: Used as a condition for starting self-diagnostics; if self-diagnostics are not started, it is judged that there is some kin d of error.
*5: Input by CAN communications
*6: Output by CAN communications Control item
