Computer Relearn Procedures - Import Audi S6 C5

INTRODUCTION

Note. Before replacing any component that scan tool suggests are faulty. Ensure that all wiring connections and harness connectors are okay. Ensure that power and ground circuits are functioning properly. For circuit identification, see appropriate WIRING DIAGRAMS article for vehicle being tested.

BODY CONTROLS

Vehicles equipped with body, air conditioning, anti-lock brake or memory computers may require a computer relearn procedure after components are replaced or the vehicle battery is disconnected. Vehicle computers memorize and store vehicle information and operation selections. When the vehicle battery is disconnected, vehicle computer memory may be lost, requiring relearning or resetting. Depending on the vehicle and how it is equipped, the following memories may exist

1. Seat position.
2. Tilt/telescoping steering wheel position.
3. Mirror position.
4. Radio presets and anti-theft code.
5. Clock.
6. Remote keyless entry custom features.
7. Door key lock entry custom features.
8. Power window or sunroof operation.

These do not affect vehicle operation. For systems that do not affect operation, see appropriate article for relearn procedures. Other computer relearn procedures are required for vehicle or system operation. These may include

1. Initial control unit programming.
2. Traction control yaw sensor initializing.
3. Multiplex communication.
4. Anti-theft system or engine immobilizer system passwords.

ENGINE CONTROLS

Vehicles equipped with powertrain control computers may require a computer relearn procedure after the vehicle battery is disconnected. Vehicle computers memorize and store vehicle operation patterns for optimum driveability and performance. When the vehicle battery is disconnected, this memory is lost, which may result in a driveability problem. Depending on the vehicle and how it is equipped, the following driveability problems may exist

1. Rough or unstable idle.
2. Hesitation or stumble.
3. Rich or lean running.
4. Poor fuel mileage.
5. Harsh or poor transmission/transaxle shift quality.

Default data is used until NEW data from each key start is stored. As the computer restores its memory from each new key start, driveability is restored.

Driveability problems may occur during the computer relearn stage. To accelerate computer relearn process after battery removal and installation, specified computer relearn procedures should be performed. See appropriate procedures for specified manufacturer.

POWERTRAIN CONTROL MODULE RESET PROCEDURE/CLEARING DIAGNOSTIC TROUBLE CODES (ALL MODELS)

Note. Some models have an anti-theft code built into radio circuit. Clearing codes cancels clock and radio settings; make note of anti-theft code and station presets before beginning reset procedure. After PCM reset, radio will not operate until anti-theft code is entered.

Note. If service check connector is connected and no DTC is stored in PCM, MIL will remain on when the ignition is turned on.

To reset Powertrain Control Module (PCM) (clear DTCs), use Honda PGM tester or OBD-II scan tool following manufacturer's instructions. After DTCs are cleared and PCM is reset, remove SCS service connector, if connected. Disconnect Honda PGM Tester or scan tool from DLC. DTCs can also be cleared by turning ignition off and removing BACK UP (RADIO) fuse (7.5-amp) from underhood fuse/relay block (located next to battery). On all models, leave fuse out for at least 10 seconds to reset PCM.

KNOWN-GOOD POWERTRAIN CONTROL MODULE SUBSTITUTION

Note. Use this procedure when diagnostic testing suggests substituting PCM with known-good unit.

On models equipped with engine immobilizer system, acquire key cut from non-immobilizer key blank. Remove PCM from test vehicle. Install known-good PCM from donor vehicle into test vehicle. Tape donor vehicle's ignition key head-to-head to test vehicles temporary key. PCM will recognize code from donor vehicle's key and allow test vehicle to be started and tested.

SYSTEM READINESS TEST CODES

If battery has been disconnected, DTCs have been cleared or PCM has been reset, readiness codes will reset. In some states part of emission testing is to ensure readiness codes are complete. If readiness codes are not complete, emission test cannot be finished.

To check if readiness codes are complete, turn ignition switch on, engine off. MIL will illuminate for 15-20 seconds. If MIL goes off, readiness codes are complete. If MIL blinks several times, one or more readiness codes are not complete.

To set each code, drive vehicle or run engine as described in following procedures.

READINESS CODE

Note. While limited diagnostic information is available, vehicle manufacturer does not support diagnostic information using aftermarket scan tools. To properly diagnose vehicle, it is recommended to use VAS 5051 scan tool with VAS 5051/1 adapter cable or VAG 1551 scan tool with 1551/3A adapter cable and VAG 1598/31 test box.

Readiness code must be generated when Engine Control Module (ECM) memory is cleared, battery voltage or ECM is disconnected. Readiness code appears on scan tool as an 8-digit display in display field 1 of MEASURING VALUE BLOCK - 086. Each of the 8 digits is related to a specific exhaust related system. During a test sequence OBD system checks function of each of the 8 systems. Test sequence once started must be run completely. During test sequence if test is successful scan tool changes display digits from "1" to "0". When readiness code is generated, display should read 0 0 0 0 0 0 0 0 in display field 1 of measuring value block 086. If during testing, a malfunction is recognized, a DTC is stored in memory. Retrieve DTCs and repair as necessary. See RETRIEVING DIAGNOSTIC TROUBLE CODES under SELF-DIAGNOSTICS SYSTEM in appropriate SELF DIAGNOSTICS article.

Readiness code is returned to 1 1 1 1 1 1 1 1 if DTC memory is erased, voltage supply to ECM is lost, or a new ECM is installed. To check readiness code, connect VAS 5051 or equivalent scan tool to DLC. DLC is located behind cover under left side of steering column. Turn ignition on. Using scan tool, select vehicle system 01 - ENGINE ELECTRONICS. From selection 1, select diagnostic function 08 - READ MEASURED VALUE BLOCK. From button field 2, enter 086 for DISPLAY GROUP - 086. Press "Q" button to confirm input. Using scan tool, observe display field 1 in display group 086. (Scheme 1)and (Scheme 2). Readiness code should display 0 0 0 0 0 0 0 0 0. If readiness code displays as specified, continue DTC testing. If no DTCs are stored testing is complete. If readiness code does not display as specified, generate readiness code. See GENERATING READINESS CODE.

Scheme 2

GENERATING READINESS CODE

Note. While limited diagnostic information is available, vehicle manufacturer does not support diagnostic information using aftermarket scan tools. To properly diagnose vehicle, it is recommended to use VAS 5051 scan tool with VAS 5051/1 adapter cable or VAG 1551 scan tool with 1551/3A adapter cable and VAG 1598/31 test box.

Note. During readiness code generating procedure, if test result is indicated as "OK" after selecting a display group, testing has already been carried out and it is okay to proceed to next work step.

Readiness code must be generated if Engine Control Module (ECM) memory is cleared, battery voltage is disconnected or ECM is disconnected. To generate readiness code, vehicle must be stationary, transmission in Park or Neutral, all electrical consumers off, A/C switched off and coolant temperature at least 176°F (80°C). If possible it is best to warm-up vehicle by test driving. Connect VAS 5051 or equivalent scan tool to DLC. DLC is located behind cover under left side of steering column.

Using scan tool, retrieve DTCs. See RETRIEVING DIAGNOSTIC TROUBLE CODES in appropriate SELF DIAGNOSTICS article. If DTCs were stored, perform appropriate test. See DIAGNOSTIC TROUBLE CODE DEFINITIONS in appropriate SELF DIAGNOSTICS article. Using scan tool, clear DTC memory. See FUNCTION 05 - CLEARING DIAGNOSTIC TROUBLE CODES under SELF-DIAGNOSTIC SYSTEM in appropriate SELF DIAGNOSTICS article. After clearing DTC memory. Follow scan tool instructions to complete readiness code generation. Using scan tool, observe display field 1, in display group 086. (Scheme 1)and (Scheme 2). Readiness code should display 0 0 0 0 0 0 0 0. If readiness code displays as specified, testing is complete.

PCM CODING (ALL MODELS)

Note. After coding ECM and starting engine for first time, allow engine to idle for several minutes so ECM can go through learn function. Idle speed may be erratic while ECM is learning.

If Engine Control Module (ECM) is replaced, it is necessary to code new ECM. If new ECM is not properly coded, the following problems may occur

1. Driveability problems (i.e., harsh shifting).
2. False malfunctions stored in ECM memory.
3. Increased fuel consumption.
4. Increased exhaust emissions.
5. Reduction in transmission life.
6. All ECM functions are not carried out (i.e., EVAP system operation).

Remove PCM from test vehicle. Install known-good PCM in test vehicle. Using Honda PGM Tester or OBD-II scan tool, rewrite immobilizer code into PCM with scan tool. This will allow known-good PCM to recognize immobilizer code and allow engine to be started and tested. After completing test, reinstall PCMs and rewrite immobilizer code with scan tool.

IMMOBILIZER (ACCORD, INSIGHT, ODYSSEY, PRELUDE & S2000)

ECM/PCM is part of immobilizer system. Replacement ECM/PCM must have immobilizer code rewritten, using Honda PGM Tester. To perform rewrite procedure requires the vehicle, all master keys, all valet keys and a Honda PGM Tester with an immobilizer program card. Any key not learned during rewrite will not start vehicle. Follow Honda PGM Tester instructions. For more information, see appropriate IMMOBILIZER SYSTEMS article in ACCESSORIES & EQUIPMENT.

All Honda engines have specific system readiness codes that are part of the on-board diagnostics for the emissions systems. If the vehicle battery has been disconnected or discharged, these codes are erased. In some states where Inspection/Maintenance (I/M) testing of vehicle emissions is performed, these codes must be set. If all the codes are not set, the I/M test cannot be completed.

The Malfunction Indicator Light (MIL) is used to display state of system readiness. To determine if readiness codes are set, turn ignition on, but do not start engine. MIL should come on for 15-20 seconds. If MIL then goes off, readiness test codes are set. If MIL blinks several times, readiness test codes are not set completely.

Note. Refer to latest Isuzu Technical Communication System (ITCS) information for reprogramming or flashing procedures. Programming PCM/EEPROM requires the use of a scan tool and special manufacturer equipment.

Connect TECH 2 scan tool to DLC and retrieve program information from PCM. Ensure that battery is fully charged. Turn ignition on. Ensure that Vehicle Interface Module cable connection is securely connected to DLC. Follow scan tool instructions to program EEPROM using latest software available from ITCS. If PCM fails to program, recheck PCM connections. Ensure that most recent ITCS information is being used. Attempt to program PCM. If it still can not be programmed properly, replace PCM. Reprogram new PCM, then perform On-Board Diagnostic II System Check. See ON-BOARD DIAGNOSTIC II SYSTEM CHECK under SELF-DIAGNOSTIC SYSTEM in appropriate SELF-DIAGNOSTICS article. Start engine and run for one minute. Use scan tool to check for any stored DTCs.

PRINCIPLES OF OPERATION

Newly released modules require configuration after being installed on the vehicle. All configurable modules will be packaged in a kit which contains a warning label and a multi-language sheet reemphasizing requirements to configure replacement modules. Powertrain Control Module (PCM) has to be standard J1962 lead.

MODULE CONFIGURATION

There are two modes of configuration data. First type requires configuration information so that module can interact with vehicle correctly. This information will be transferred into new module so that new module will contain same settings as old module. Modules on vehicle that require configuration when installing a replacement module are

1. Anti-lock brake control module with traction control.
2. Anti-lock brake control module with traction control and dynamitic stability control.
3. Remote keyless entry driver door module.
4. Steering lock control module.
5. Driver seat module.
6. Audio control module.
7. Vehicle emergency message system/Jaguar assist.
8. Dual automatic temperature control.
9. Instrument cluster with message center.
10. Rear electronic module.
11. General electronic module.

To carry out configuration process, upload old information from old module using PDU (if applicable). Install new module. For additional information on the anti-lock brake control module, appropriate ANTI-LOCK article in BRAKES. For additional information on the DDM, see appropriate POWER DOOR LOCK article in ACCESSORIES & EQUIPMENT. For additional information on the instrument cluster, see appropriate INSTRUMENT PANELS article in ACCESSORIES & EQUIPMENT. For additional information on the GEM and the REM, appropriate BODY CONTROL MODULES article in ACCESSORIES & EQUIPMENT. PDU will not retain stored configuration information for longer than 24 hours. Download stored information into new module using PDU (if applicable).

CUSTOMER DRIVEN PREFERENCES

Second type of configuration data is customer preference driven. These are items that the customer may or may not want to have enabled. Typically, customer preference items can be toggled on or off with compatible scan tool. You may need to ask the customer which preferences they had enabled prior to installation of new module. To carry out customer configuration process, use PDU. On PDU select CUSTOMER PREFERENCE INDEX for modules on the vehicle that have customer preference items. Configure items as necessary. See CUSTOMER PREFERENCE INDEX table.

CUSTOMER PREFERENCE INDEX

S-Type

If battery has been disconnected, engine should be allowed to idle for three minutes as stored idle and drive values contained within PCM have been lost. This may cause a driveability concern if following procedure is not carried out. Once the engine reaches normal operating temperature, engine speed should be increased to 1200 RPM and maintained for approximately two minutes. This will allow PCM to relearn idle values. For PCM to complete it's learning strategy, the vehicle should be driven for approximately 5 miles of varied driving.

X-Type

If battery has been disconnected, engine should be allowed to idle until it has reached normal operating temperature as stored idle and drive values contained within the PCM have been lost. Allow vehicle to idle for a further three minutes. Drive vehicle at constant speeds of approximately 30, 40, 50,60 and 70 mph for three minutes each. This will allow PCM to relearn idle values. Driveability concern may exist if procedure is not carried out.

POWER WINDOW CALIBRATION (XK8)

If battery is disconnected, power windows will require calibration to establish upper and lower stop points. Turn ignition on. Lower window(s) to stop and hold switch for 2 seconds. Raise window(s) to stop and hold switch for 2 seconds. Repeat procedure for all power windows. Turn ignition off.

RADIO SECURITY CODE

If battery is disconnected, radio will require anti-theft security code to be entered. Turn radio on. Radio should display CODE. Using preset buttons, enter code number from security card. A "beep" will sound when correct code is entered. If code is incorrectly entered after 3 successive attempts, radio must be left on for one hour before it will accept code entry.

REMOTE KEYLESS ENTRY TRANSMITTER

Note. All remote transmitters are programmable and must be set at the same time. If an attempt is made to program a fifth remote entry device after four remote entry devices have already been programmed, the attempt shall erase all remote entry device associations and start a new set of four remote entry device associations with fifth remote device programming attempt.

Programming (or reprogram) of remote transmitters into remote keyless entry Driver Door Module (DDM) is carried out with PDU. Due to complexity of the electronics involved with the remote keyless entry, of which the DDM is a part, and the multiplexed communication network which are connected to it preclude the use of general electrical test equipment. Therefore, reference should be made to the PDU User Guide for detailed instructions on programming the remote transmitters.

TRANSMISSION CONTROL MODULE DRIVEABILITY COMPUTER RELEARN PROCEDURE

Manufacturer does not provide a specific computer relearn procedure for obtaining proper driveability. If vehicle battery was disconnected or TCM was replaced, driving the vehicle will enable the TCM to perform a computer relearn procedure for obtaining proper driveability. Inform customer that driveability may differ from what they are accustomed to until the TCM completes the computer relearn procedure.

KIA

After disconnecting battery or replacing ECM, drive vehicle to enable ECM to relearn driveability. Inform your customer that they may experience driveability different from what they are accustomed to until ECM completes relearn function.

LAND ROVER

To enable shorter cranking times, when ignition is turned off, ECM memorizes crankshaft and camshaft positions. If battery or ECM is disconnected, memory is lost. Drive vehicle to enable ECM to relearn driveability. Inform your customer that they may experience driveability different from what they are accustomed to until ECM completes relearn function.

IMMOBILIZER

If ECM is replaced ECM must learn identification code for immobilizer ECU and remote handsets. A Land Rover TestBook must be used to reconfigure the immobilization system.

If battery is disconnected, power windows will require calibration to establish upper and lower stop points. Immediately after Central Control Unit (CCU) or battery is connected, CCU will energize down contacts on all window switches. To ensure calibration is successful; ensure that alarm is disarmed and vehicle is unlocked, that all doors and tailgate are in closed position, that sunroof is open to full hardback or softback position. DO NOT open any door until calibration procedure is completed. Turn ignition on, using appropriate window switch raise each window until motor stalls and window is fully closed. Turn ignition off. If calibration is not successful CCU will sound a warning for about .8 seconds and windows will fully lower. If calibration fails, repeat procedure.

LEXUS

After disconnecting battery or replacing ECM, drive vehicle to enable ECM to relearn driveability. Inform your customer that they may experience driveability different from what they are accustomed to until ECM completes relearn function.

IMMOBILIZER SYSTEM

Note. Not all models are equipped with immobilizer system. Models equipped with immobilizer system can be identified by ignition key having a solid urethane head.

Note. A valid key must be available when replacing PCM or immobilizer unit, or both components must be replaced. When replacing an immobilizer system component, all working keys need to be reprogrammed into system. Replacing PCM or immobilizer unit will erase previously programmed keys.

NEW TRANSPONDER KEY CODE

Note. This must be done when a new transponder key ECU is installed. The new transponder key ECU is in automatic key code registration mode. Up to 3 key codes and one sub-key can be registered at one time. In automatic registration mode, last key registered becomes sub-key.

1. Security indicator will flash until first key is inserted into ignition switch. Insert NEW key in ignition switch.
2. Once key registration is under way, security indicator should turn off. After key registration is complete, security indicator should illuminate. Remove NEW key.
3. If programming additional keys, repeat process starting with step 1 . If additional keys do not need programming, procedure is complete. Security indicator should go out once last key (sub-key) is registered.
4. After registration is complete and system is operating normally, when ignition key is removed from ignition lock cylinder, security indicator should flash indicating system is properly functioning. If a key is not inserted into ignition switch with transponder key ECU in automatic registration mode, security indicator will remain illuminated indicating keys have not been registered.

PROGRAMMING POWERTRAIN CONTROL MODULE

Note. Before performing PCM programming procedure, check for any applicable Technical Service Bulletins (TSBs) that may apply to vehicle application.

Description

Flash Electronically Erasable Programmable Read Only Memory (EEPROM) is contained in an Integrated Circuit (IC) inside of Powertrain Control Module (PCM). The EEPROM contains the vehicle strategy and any calibration information specific to vehicle. The IC is reprogrammable and at times it may become necessary to reprogram or reflash the entire contents. This is usually due to an after production strategy change or the Flash Vehicle Identification (VID) Block has been previously reprogrammed and has reached its limit. The VID block can be tailored to accommodate various hardware changes made since vehicle production. This procedure can only be performed using Ford's Service Bay Technical System (SBTS) or equivalent.

A replacement PCM will have a label stating PROGRAMMING REQUIRED. This indicates that it is necessary to retrieve VID data from the original PCM before removing PCM from vehicle. This procedure can be performed using New Generation Star (007-00500) scan tool or equivalent. See FLASH VEHICLE IDENTIFICATION BLOCK PROCEDURE . If original PCM is damaged, nonfunctional or incapable of communicating, it will be necessary to manually reprogram VID block. This procedure can only be performed by contacting the "AS BUILT" data center for programming information.

Flash Vehicle Identification Block Procedure

Note. If using a generic scan tool, follow scan tool manufacturer's instructions to perform this procedure.

1. To perform this procedure NGS scan tool, Ford Service Function (FSF) card and NGS Flash Cable (007-00531) must be used. Plug flash cable into scan tool. Plug other end of flash cable into Data Link Connector (DLC). From the scan tool main menu, select SERVICE BAY FUNCTIONS, POWERTRAIN CONTROL MODULE and then PROGRAMMABLE MODULE INSTALLATION.
2. Scan tool display should show 2 selections. The first is selection is for old PCM information to be retrieved and stored. The second selection is for restoring new PCM with information that has been retrieved from the old PCM. Follow scan tool display instructions or refer to instruction sheet included with FSF card. If Flash Vehicle Identification (VID) Block has been reprogrammed previously, scan tool will display a message indicating the need to reflash entire Integrated Circuit (IC). This procedure can only be performed using Ford's Worldwide Diagnostic System (WDS).
