INTRODUCTION
The TCM receives signals from the vehicle speed sensor and PNP switch. Then it provides shift control or
lock-up control via CVT solenoid valves.
The TCM also communicates with the ECM by means of signals
sent from sensing elements used with the OBD-related parts of the
CVT system for malfunction-diagnostic purposes. The TCM is capa-
ble of diagnosing malfunctioning parts while the ECM can store mal-
functions in its memory.
Input and output signals must always be correct and stable in the
operation of the CVT system. The CVT system must be in good
operating condition and be free of valve seizure, solenoid valve mal-
function, etc.
It is much more difficult to diagnose a malfunction that occurs inter-
mittently rather than continuously. Most intermittent malfunctions are
caused by poor electric connections or improper wiring. In this case,
careful checking of suspected circuits may help prevent the replace-
ment of good parts.
A visual check only may not find the cause of the malfunctions. A
road test with CONSULT-III (or GST) or a circuit tester connected
should be performed. Follow the “DETAILED FLOW”.
Before undertaking actual checks, take a few minutes to talk with a
customer who approaches with a driveability complaint. The cus-
tomer can supply good information about such malfunctions, espe-
cially intermittent ones. Find out what symptoms are present and
under what conditions they occur. A “Diagnostic Work Sheet” as
shown on the example (Refer to TM-177
) should be used.
Start your diagnosis by looking for “conventional” malfunctions first.
This will help troubleshoot driveability malfunctions on an electroni-
cally controlled engine vehicle.
Also check related Service Bulletins.
DETAILED FLOW
1.COLLECT THE INFORMATION FROM THE CUSTOMER
Get the detailed information from the customer about the symptom (the condition and the environment when
the incident/malfunction occurred) using the diagnosis work sheet. Refer to TM-177, "
Diagnostic Work Sheet".
>> GO TO 2.
2.CHECK SYMPTOM 1
Check the following items based on the information obtained from the customer.
 Fail-safe. Refer to TM-283, "
Fail-safe".
 CVT fluid inspection. Refer to TM-304, "
Inspection".
 Line pressure test. Refer to TM-308, "

HYDRAULIC CONTROL SYSTEM
Normal Control
Optimize the line pressure and secondary pressure, depending on driving conditions, on the basis of the throt-
tle position, the engine speed, the primary pulley (input) revolution speed, the secondary pulley (output) revo-
lution speed, the brake signal, the PNP switch signal, the lock-up signal, the voltage, the target gear ratio, the
fluid temperature, and the fluid pressure.
Feedback Control
For the normal fluid control and the select fluid control, secondary pressure is detected for feedback control by
using a secondary pressure sensor to set a high-precision secondary pressure.

position and reduces shifting and lock-up shocks.
TCM FUNCTION
The function of the TCM is to:
 Receive input signals sent from various switches and sensors.
 Determine required line pressure, shifting point, and lock-up operation.
 Send required output signals to the step motor and the respective solenoids.
