Toyota Programming

(AM/ASA3)



What is SAE J2534?

► Proposed by U.S. Environmental Protection Agency (EPA)

► Originated as an U.S. industry standard for programming emission related ECUs in the independent aftermarket service environment

► Became a standard for a general purpose vehicle interface

► Evolved into 2 specifications plus a third on the horizon:

J2534-1 Recommended practice for emission ECU reprogramming

J2534-2 Specification for Non-emission related systems and 96-03 ECUs

J2534-3 is a testing procedure to prove correct implementation.

(AM/ASA3)



What is SAE J2534-1?

Originally became effective with introduction of MY’2004 vehicles.

► Defines interface (API) between PC host applications and vehicle interface device (Flasher).

► Specifies emission vehicle physical interfaces and protocols.

► Applies to all MY’1996 to present vehicles with re-programmable ECUs.

MY 2004 and later vehicles MUST support reprogramming via J1962 connector.

MY ’96 – ‘03 vehicles may require reprogramming via proprietary data link connector.

(AM/ASA3)



What is SAE J2534-2?

Extension to specification to add physical interfaces and protocols beyond those referenced in J2534-1 (Non-emission related systems)

Additions for the proposed ballot are:

GM 8192 UART

Honda Diag-H

Ford MS-CAN

Volvo CAN (2 channels)

Multiple Protocols (simultaneously?)

Analog Measurement

J2534 Questions…

After reflash, initialization procedures which require a scantool…

Anti-theft systems (Passlock, PATS)

IPC

SDL (airbag module)

Case Learn

Diesel TDC offset

(AM/ASA3)



J2534 Questions…

TSB may not explain why a reflash is required

Often the problems meant to be corrected with a reflash are not explained in a TSB.

The vehicle may not be flashable

I.E. Suzuki?

J2534 Calibration files may not be available for downloading

Not all vehicle manufacturers have complied with J2534 (Suzuki)

Other adapters may be needed for non-emission related flashes.

96-03 vehicles are not required to use the J1962 connector.

Summary so far…

J2534-1 is implemented 2004 – present. Still, not all manufacturers are

compliant. (Suzuki is being investigated)

J2534-2 is a work in progress. Some manufacturers are compliant (GM).

Use NASTF.org to eliminate most of the confusion. The matrix for most

manufacturers explains the required tools & software for completing the repair.

A J2534 device may be only one of a couple tools required to complete the

repair. You may still need a scan tool to complete the repair!

(AM/ASA3)



Flasher Pro

PC/Host Interface:

Ethernet or USB connection to

a PC for vehicle programming

and firmware updates.

Vehicle Interface (all makes, all models)

Connects to the OBDII J1962 DLC and supports the

following protocols.

1 CAN2 Single Wire

2 J1850PWM+ , J1850VPW

3 CAN2+

6 CAN+ (CAN-C only), SCI A Engine, 5v-20v out

7 ISO-9141 K-line, SCI A Engine, SCI A Trans, SCI B Engine

9 SCI B Trans, 5v-20v out or short-to-ground

10 J1850PWM-

11 CAN2- 5v-20v out

12 SCI B Engine 5v-20v out or short-to-ground

14 CAN- (CAN-C only), SCI A Trans 5v-20v out

15 ISO L Line, SCI B Trans, Short-to-ground

Essential Features:

In-shop vehicle programming module (all makes, all models)

Conforms to SAE J2534-1 recommended practice for pass through

Industry standard application programming interface (API)

(AM/ASA3)



Flasher LT

There are 4 variants of the Flasher LT:

Flasher LT-Import supports CAN, ISO-9141, and

ISO-14230/ffKWP2000

Flasher LT-GM supports CAN, J1850 VPW (GM

Class 2), and GM Single-Wire CAN protocols

Flasher LT-Ford supports CAN and J1850 PWM

(Ford SCP) protocols

Flasher LT-Chrysler supports CAN, J2610 (SCI),

and J1850 VPW

(AM/ASA3)



Mastertech VCI… Emerging Technologies and Standards…

(AM/ASA3)



Mastertech VCI

► Common Hardware with MDI (Multiple Diagnostic

Interface)

► Successor to the Tech 2.

First General Motors dealer release was July 2007,

J2534 ECU programming only.

Nov 2008 Global Architecture introduced in Buick

LaCrosse/Lucerne and Chevrolet Camaro

MSCAN/Expansion Bus networks will be phased in

until 2012. *Tech 2 cannot work on these

(AM/ASA3)



MDI & Mastertech VCI Similarities

► GM MDI supports GM protocols

UART, Class 2 (J1850 VPW), KWP2000, GMLAN (SW/DW)

► GM MDI supports J2534 (for General Motors vehicles)

► GM MDI conforms to the MVCI & ISO 22900 standards.

► Mastertech VCI adds non-GM protocols

J1850PWM, ISO9141-2, DDL2, KW71, KW81, KW82, H92,

H95, H99, Ford DCL, Chrysler SCI, Chrysler CCD, etc.

Capable of adding non-General Motors J2534

► Mastertech VCI is architecturally capable of running GDS

(AM/ASA3)



J2534 & ISO 22900 Implications…and… Which tool is best for me.

The Flasher Pro… In-shop vehicle programming module (all makes, all models)

Conforms to SAE J2534-1 recommended practice for pass through

Industry standard application programming interface (API)

The Mastertech VCI… Mastertech OEM Applications (Honda, Toyota,)

Tech 1A OEM Applications (’96 & up GM, Isuzu, Suzuki)

Based on GM MDI platform

Conforms to the ISO22900 Standard (MVCI, D-PDU API)

J2534 Flashing

Aftermarket Scan Tool for GM, Ford, Chrysler, Honda, Nissan

(AM/ASA3)



Final Summary

• J2534 is here to stay. It is a good method for emission-related and

SOME non-emission related programming.

• Emerging ISO standards integrate scan tool and programming

functions in one tool. These standards are already being adopted by

OEMs.

• You rarely fix a car with one tool. Post-programming scan tool

functions are required in many cases.

Obtaining Calibrations

► TSB search for applicable updates

► Vehicle Certification Label for use with TSB

► Visit Ford website: http://www.motorcraft.com for calibrations

http://www.motorcraft.com/

(AM/ASA3)

(AM/ASA3)



Vehicle Certification Label:

Base Engine Calibration Information

Base Engine Calibration Information is located in the

lower right corner of the Vehicle Certification (VC) Label.

Engine calibration information is limited to a maximum of

five characters per line (two lines maximum).

(AM/ASA3)



Calibration Catch Code

Beginning in 2000, a 4-digit alpha-numeric code, referred to

as Calibration Catch Code, appears in parentheses at the

end of the calibration code.

Example; 9-EQA-BBD 9 (BAX3)

The BAX3 in this example is the Calibration Catch Code.

This Calibration Catch Code information is attached with a

tag to the PCM connector and, on some models, the

Calibration Catch Code tag may also be located on the "A"

pillar or inner fender. This Calibration Catch Code is needed

to determine calibration number.

(AM/ASA3)



Authorized Modification Label

If a module is programmed because of an emissions recall or required emissions-related

TSB, an Authorized Modification Label must be applied to the module. These labels are

available at the Ford or Lincoln/Mercury dealership parts counter.

Part name: Authorized Modification Label

Part number: FPS 8262
