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-10
) 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.

ON BOARD DIAGNOSTIC (OBD) SYSTEM
Only one set of freeze frame data (either 1st trip freeze frame data or freeze frame data) can be stored in the
ECM. 1st trip freeze frame data is stored in the ECM memory along with the 1st trip DTC. There is no priority
for 1st trip freeze frame data, and it is updated each time a different 1st trip DTC is detected. However, once
freeze frame data (2nd trip detection/MI on) is stored in the ECM memory, 1st trip freeze frame data is no
longer stored. Remember, only one set of freeze frame data can be stored in the ECM. The ECM has the fol-
lowing priorities to update the data.
Both 1st trip freeze frame data and freeze frame data (along with the DTC) are cleared when the ECM mem-
ory is erased.
How to Erase DTC
 The diagnostic trouble code can be erased by CONSULT-III, GST or ECM DIAGNOSTIC TEST MODE as
described below.
-If the battery cable is disconnected, the diagnostic trouble code will be lost within 24 hours.
-When erasing the DTC, using CONSULT-III or GST is easier and quicker than switching the mode
selector on the ECM.
 The following emission-related diagnostic information is cleared from the ECM memory when erasing DTC
related to OBD. For details, refer to EC-389, "
DTCIndex".
-Diagnostic trouble codes (DTC)
-1st trip diagnostic trouble codes (1st trip DTC)
-Freeze frame data
-1st trip freeze frame data
-System readiness test (SRT) codes
-Test values
How to Erase DTC (With CONSULT-III)
The emission related diagnostic information in the TCM and ECM can be erased by selecting “ALL Erase” in
the “Description” of “FINAL CHECK” mode with CONSULT-III.
How to Erase DTC (With GST)
1. If the ignition switch stays ON after repair work, be sure to turn ignition switch OFF once. Wait at least 10
seconds and then turn it ON (engine stopped) again.
2. Select Mode 4 with GST (Generic Scan Tool). For details, refer to EC-113, "
CONSULT-III Function".
MALFUNCTION INDICATOR (MI)
Description
The MI is located on the instrument panel.
1. The MI is turned ON when the ignition switch is turned ON with-
out the engine running. This is a bulb check.
 If the MI is not turned ON, refer to EC-346, "
Component Func-
tion Check".
2. The MI is turned OFF when the engine is started.
If the MI remains ON, the on board diagnostic system has
detected an engine system malfunction.

U1000 CAN COMM CIRCUIT
DescriptionINFOID:0000000003848946
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 malfunction detection ability.
Many electronic 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 con-
nected with 2 communication lines (CAN-H and CAN-L) allowing a high rate of information transmission with
less wiring. Each control unit transmits/receives data but selectively reads required data only.
