TCM Signal Test
Inspection Tool
Use a DMM to measure voltage and circuit continuity.
Also use an oscilloscope to measure waveform. Refer
to the following table for the specified ranges or
reference waveform. Since the TCM terminals are extremely small, use
appropriate test adapter from the test adapter kit. This
will make measurement easier.

Repair Instructions
Transmission Controls Module (TCM) Replacement
Description
The following A - C steps provide an overview
procedure to replace and reprogram a TCM. Each A -C
steps is explained further in this section.
A. Replace the old TCM with the new TCM.
B. Program the latest software and calibrations into the
new TCM using the Service Programming System
(SPS) if released. If not released, do not perform this
and skip to Step C.
C. Program the vehicle identification number (VIN) into
the TCM.
A. Removal and Installation
Removal Procedure 1. Disconnect the negative battery cable.
2. Disconnect the TCM harness connectors (1).
3. Loosen nuts (2) and remove the TCM (3) from the bracket (4).
Installation Procedure
Follow the removal steps in the reverse order. Be sure
that the connectors are securely fastened.
B. Programming Software and Calibrations
Program the latest software/ calibrations if released.
Refer to Service Programming System (SPS)
Description and SPS (Remote Procedure) or SPS
(Pass-Thru Procedure) in this section. If not released,
do not perform this and skip to Step C.
C. Programming Vehicle Identification Number
(VIN) Notice:
If you have performed SPS in the previous
step, VIN has prgrommaned already. Programming VIN
is not necessary in this step.
1. Install a scan tool.
2. Turn ON the ignition, with the engine OFF.
3. Select Diagnostics > appropriate vehicle identification > AT JR405E > Programming >
Program VIN.
4. If you installed a new, skip to step 8. If you installed a reused TCM from another vehicle or incorrect
VIN is programmed before, the TCM might be
locked already. In order to get programming
approval, the on-screen displays a message to
user. Get programming approval from the TIS
2000 using the following procedure:
a. Connect a scan tool to the terminal that installed TIS 2000 with the latest software and
the hardware key is plugged into port.
b. Turn ON the scan tool and keep at title screen.
c. Launch the TIS application.
d. Select the Security Access at the main screen.
e. Highlight the “Tech 2" on the Diagnostic Tool Selection screen and click “Next”.
f. Click “Close” on the Security Access Enabled screen.
g. Turn OFF the scan tool.
h. Disconnect the scan tool from the terminal.
5. Install a scan tool to the vehicle.
6. Turn ON the ignition, with the engine OFF.
7. Select Diagnostics > appropriate vehicle identification > AT JR405E > Programming >
Program VIN.
8. Input 17 digits of correct VIN.
9. After complete the programming, turn OFF/ ON the ignition.
10. Select Diagnostics > Lock ECU.
11. Follow the on-screen instructions and turn OFF/ ON the ignition.
Service Programming System (SPS)
Description
The service programming system (SPS) allows a
technician to program a control module through the
data link connector (DLC). The information transfer
circuit that is used at the DLC is the same serial data
circuit used by the scan tool for retrieving DTCs,
displaying data, clearing DTCs etc. This procedure
offers the ability to install software/ calibrations
matched to a particular vehicle.
Most control modules have two types of memory. The
software/ calibrations reside in the flash memory. The
two types of memory are listed below:

7A2-140 TRANSMISSION CONTROL SYSTEM (JR405E)
• Electrically Erasable Programmable Read OnlyMemory (EEPROM)
This type of memory allows selected portions of
memory to be programmed while other portions
remain unchanged.
Certain learned values reside in the EEPROM,
such as:
- The vehicle identification number (VIN)
- The software/ calibrations identification numbers
- The control module security information
• Flash Read Only Memory-Flash Memory
Flash memory has increased memory storage capacity.
During programming, all information within this type of
memory is erased, and then replaced with entirely new
information.
Service Programming Methods
The two methods of programming a TCM are listed
below:
• Remote Programming
• Pass Thru Programming
For information on programming a TCM using one of
the methods listed above, refer to Service
Programming System (SPS) (Remote Procedure) or
Service Programming System (SPS) (Pass-Thru
Procedure).
Before Programming a Control Module
Important: DO NOT program an existing TCM with the
identical software/ calibration package. This procedure
is not a short cut to correct the driveability condition.
This is an ineffective repair. An TCM should only be
programmed when the following occurs:
• When a service procedure instructs you to replace the TCM.
• An updated software/ calibrations is released.
Ensure that the following conditions are met before
programming a TCM:
• The scan tool PCMCIA card is programmed with the latest software.
• The TIS 2000 is installed with the latest software.
• The hardware key is plugged into the computer port.
• Vehicle system voltage:
- There are no charging system concerns. Allcharging system concerns must be repaired
before programming the TCM.
- The battery voltage is greater than 12 volts but less than 16 volts. The battery must be fully
charged before programming the TCM.
- A battery charger is NOT connected to the vehicles battery. Incorrect system voltage or
voltage fluctuations from a battery charger may
cause programming failure or TCM damage. - Turn OFF or disable any system that may put a
load on the vehicles battery. Turn OFF or
disable systems such as:
◊ Heating, ventilation, and air conditioning
(HVAC) systems
◊ Headlights
◊ Room lights
◊ Accessory equipment
• The ignition switch is in the proper position. The scan tool prompts you to turn ON the ignition, with
the engine OFF. DO NOT change the position of
the ignition switch during the programming
procedure unless instructed to do so.
• All tool connections are secure:
- The RS-232 cable
- The connection at the DLC
- The voltage supply circuits
• DO NOT disturb the tool harnesses while programming. If an interruption occurs during the
programming procedure, programming failure or
TCM damage may occur.
• If you are performing the Pass-Thru programming procedure using a notebook computer without the
power cord, ensure that the internal battery is fully
charged.
Service Programming System (SPS)
(Remote Procedure)
Notice: Some module will not accept SPS remote
procedure using 10MB PCMCIA card. In such case,
use 32MB PCMCIA card or SPS pass-thru procedure.
The Remote SPS method is a three-step process that
involves the following procedures:
1. Connecting the scan tool to the vehicle and obtaining the information from the TCM.
2. Connecting the scan tool to the terminal and downloading a new calibration file from the
terminal into the scan tool memory.
3. Reconnecting the scan tool to the vehicle and uploading the new calibration file into the TCM.
Performing the Remote Procedure 1. Connect a scan tool to the vehicle and obtain the TCM information using the following procedure:
Notice: Ensure the TCM is installed in the vehicle and
the battery is fully charged before programming.
a. Install a scan tool.
b. Turn ON the ignition, with the engine OFF.
c. Select Service Programming System (SPS) > Request Info.
