Computer Relearn Procedures Cadillac Seville V

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 secondary memories may exist

1. Air conditioning. See appropriate AUTOMATIC A/C-HEATER SYSTEMS article in AIR CONDITIONING & HEATING.
2. Clock.
3. Power window operation. See appropriate POWER WINDOWS article in ACCESSORIES & EQUIPMENT.
4. Radio presets.
5. Remote keyless entry and/or keyless entry keypad custom features. See appropriate REMOTE KEYLESS ENTRY SYSTEMS article in ACCESSORIES & EQUIPMENT.
6. Sun roof operation. See appropriate POWER SUN ROOF article in ACCESSORIES & EQUIPMENT.

These do not affect primary vehicle systems. For secondary vehicle systems, see appropriate article for relearn procedures. Other computer relearn procedures are required for primary vehicle 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.

Description

Automatic Temperature Control (ATC) module must be reset or recalibrated each time a door actuator is replaced or when ATC module is replaced. It is necessary for ATC module to learn feedback voltage values for each door stop position for all doors in front HVAC unit housing and rear HVAC unit housing. If an actuator blend door, mode door, or if recirculation door, or door actuator are out of calibration, ATC system will not perform at maximum efficiency.

Test Procedure

1. Turn ignition switch to ON position. Simultaneously depress and hold power (PWR) button and recirculation icon button of ATC control panel for 5 seconds, then release. DELAY and recirculation symbol of ATC control panel Vacuum Fluorescent (VF) display window will flash when calibration procedure has begun. Calibration procedure should take less than 20 seconds to complete.
2. When DELAY and recirculation icon in ATC control panel VF display stop flashing, calibration procedure has been completed successfully. If VF display remains flashing for longer than 20 seconds, ATC module has detected a fault with a actuator or actuator door operation during calibration test, and DTC/fault message has been stored in ATC module. VF display icons will continuously flash, even after ignition switch has been cycled off and on, until either another calibration test is successfully completed, or until vehicle has been driven about 3 miles. For diagnostic procedures for calibration test failure, see SELF-DIAGNOSTIC SYSTEM in appropriate AUTOMATIC A/C-HEATER SYSTEMS article in AIR CONDITIONING & HEATING.

A/C-HEATER SYSTEM (SEBRING CONVERTIBLE, SEBRING SEDAN & STRATUS SEDAN)

Anytime negative battery cable is disconnected or battery voltage to Body Control Module (BCM) is less than 10 volts, blend, mode and recirculation door actuators for A/C and heater system must be recalibrated. Prior to replacing suspect part, disconnect negative battery cable for one minute. This will automatically initiate calibration.

PROGRAMMING POWERTRAIN CONTROL MODULE (ALL MODELS)

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

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 Vehicle Identification (VID) area 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) tester or equivalent. See FLASH VEHICLE IDENTIFICATION (VID) BLOCK PROCEDURE . If original PCM is nonfunctional, it will be necessary to manually reprogram VID block. This procedure can only be performed using Ford's Service Bay Technical System (SBTS) or equivalent.

Flash Vehicle Identification (VID) Block Procedure

Note. If using a generic scan tool, follow scan tool manufacturer's instructions to perform FLASH VEHICLE IDENTIFICATION (VID) BLOCK PROCEDURE.

NOTE: If PCM programming fails, ensure all electrical connections on PCM are okay. Check Techline® for latest software. If EEPROM programming still fails, replace PCM.
4. Start and warm engine until engine coolant temperature is at least 170°F (77°C). This will allow TDC offset to be programmed into the PCM if necessary. PCM has the ability to determine amount of offset required to bring engine to TDC. PCM uses TDC to determine proper fuel injection pump timing. If TDC offset is not programmed, DTC P1214 will be set.

TDC Offset Learn Procedure (6.5L Diesel)

1. Procedure must be performed if any of following have been done or exists: If sent here from DTC P1214. Engine has been replaced. CKP sensor or engine front cover has been replaced. PCM and fuel injection pump have been replaced. NOTE: DO NOT perform procedure unless sent here from DTC P1214 or one of the components listed above have been replaced.
2. PCM has the ability to determine amount of offset required to bring the engine to TDC when TDC offset is not present or has been cleared. This procedure must be performed to allow PCM to be updated with correct TDC offset for vehicle application.
3. Install scan tool. Start and warm engine until engine coolant temperature is at least 170°F (77°C). Using scan tool, clear DTCs from PCM. Turn ignition switch to ON position, engine off. Fully depress and hold throttle at full throttle for at least 45 seconds.

5. With engine running, use scan tool to verify engine coolant temperature is greater than 170°F (77°C). It may be necessary to drive vehicle to obtain correct engine coolant temperature if engine coolant temperature is less than specified.
6. As soon at engine coolant temperature is greater than 170°F (77°C) and engine speed is less than 1500 RPM, the PCM automatically learns a new TDC offset. The new TDC offset will overwrite the previous TDC offset. Using scan tool, note new TDC offset. TDC offset should be -.25 to -.75.
7. Turn engine off. If TDC offset is not within specification, go to next step. If TDC offset is within specification, TDC offset learn procedure is complete.
8. Using Flange Nut Wrench (J41089), loosen fuel injection pump retaining nuts. Fuel injection pump must be rotated to change TDC offset. Rotating fuel injection pump .039" (1.00 mm) will change TDC offset about 2 degrees. Rotating fuel injection pump toward driver's side of vehicle will produce a positive (+) number and rotating fuel injection pump toward passenger's side of vehicle will produce a negative (-) number.
9. Using Fuel Injection Pump Wrench (J 29872-A), slightly rotate fuel injection pump. Tighten fuel injection pump retaining nuts.
10. Repeat step 3 through 9 until TDC offset is within specification. If proper TDC offset cannot be obtained, check the following: Ensure engine coolant temperature is greater than 170°F (77°C). Harness connectors at PCM are properly installed. Harness connectors at injection timing stepper motor on side of fuel injection pump is correctly installed. Ensure latest Techline® software was used. Check for proper base installation of fuel injection pump. The electric engine shutoff solenoid on top of fuel injection pump should be about up and down. Fuel injection pump may be defective, although manufacturer states this is highly unlikely.
