Buick Encore: Rear differential clutch control module programming and setup
Special Tools
EL-49642 SPS Programming Support Tool
For equivalent regional tools, refer to Special Tools.
NOTE:
- DO NOT program a control module unless directed to by a service
procedure or a service bulletin. If the ECU is not properly configured with
the correct calibration software, the ECU will not control all of the
vehicle
features properly.
- Ensure the programming tool is equipped with the latest software and
is
securely connected to the data link connector. If there is an interruption
during programming, programming failure or ECU damage may occur.
- Stable battery voltage is critical during programming. Any
fluctuation,
spiking, over voltage or loss of voltage will interrupt programming. Install
the EL-49642 SPS programming support tool to maintain system voltage. If
not available, connect a fully charged 12 V jumper or booster pack
disconnected from the AC voltage supply. DO NOT connect a battery
charger.
- Turn OFF or disable systems that may put a load on the vehicles
battery
such as; interior lights, exterior lights (including daytime running
lights),
HVAC, radio, etc.
- During the programming procedure, follow the SPS prompts for the
correct ignition switch position.
- Clear DTCs after programming is complete. Clearing powertrain DTCs
will
set the Inspection/Maintenance (I/M) system status indicators to NO.
Diagnostic Aids
- If replacing the Rear Differential Clutch Control Module, the module
needs to be programmed with a rear
differential clutch service calibration value. The clutch calibration
service value is a number that is stored
in the RDCM memory and stamped on the rear differential housing. The number
must be programmed
into the new Rear Differential Clutch Control Module using SPS. If
communication to the RDCM cannot
be established, the number stamped on the rear differential housing can be
manually programmed into the
new RDCM.
- If replacing the rear differential clutch assembly and keeping the old
RDCM, the RDCM will only need to
be configured with the number stamped on the housing using a scan tool.
Replace and Program Control Module
To program a replacement control module, perform the following procedure:
- Install EL-49642 SPS programming support tool.
- Access the Service Programming System (SPS) and follow the on-screen
instructions.
NOTE: The next step will copy the 2 digit rear differential clutch
service
calibration value from the old module and store it in the computer's hard
drive. After completing the step, the Rear Differential Clutch Control
Module can now be removed and replaced.
- On the SPS Supported Controllers screen, select RDCM Rear Differential
Clutch Control Module-
Prepare the Control Module for Removal and follow the on-screen
instructions.
NOTE: The Rear Differential Clutch Control Module can now be
removed and
replaced.
- On the SPS Supported Controllers screen, select RDCM Rear Differential
Clutch Control Module-
Programming and follow the on-screen instructions.
- On the SPS Supported Controllers screen, select RDCM Rear Differential
Clutch Control Module- Setup
and Configuration; follow the on-screen instructions.
- At the end of programming, choose the "Clear All DTCs" function on the
SPS screen.
Reprogram Control Module
To reprogram an existing control module, perform the following procedure:
- Install EL-49642 SPS programming support tool.
- Access the Service Programming System (SPS) and follow the on-screen
instructions.
- On the SPS Supported Controllers screen, select RDCM Rear Differential
Clutch Control Module-
Programming and follow the on-screen instructions.
- On the SPS Supported Controllers screen, select RDCM Rear Differential
Clutch Control Module- Setup
and Configuration; follow the on-screen instructions.
- At the end of programming, choose the "Clear All DTCs" function on the
SPS screen.
Unsuccessful Programming Recovery
In the event of an interrupted or unsuccessful programming event, perform the
following steps:
- DO NOT turn the ignition OFF. Ensure that all ECU, DLC and programming
tool connections are secure
and the TIS terminal operating software is up to date.
- Attempt to reprogram the ECU.
- If the ECU can still not be programmed, turn the ignition OFF for at
least one minute.
- Turn the ignition ON and attempt to reprogram the ECU. The ECU should
program.
- If the ECU still cannot be programmed, replace the ECU.
REMOTE CONTROL DOOR LOCK RECEIVER PROGRAMMING AND SETUP
Diagnostic Aids
The remote control door lock receiver only functions as an antenna, receiving
the signals sent by the keyless
entry transmitter and forwarding them to the body control module (BCM). The
keyless entry software is
contained wholly within the BCM.
Replace and Program ECU or Reprogram ECU
This ECU does not require SPS programming or any setup procedures.
SEAT MEMORY CONTROL MODULE PROGRAMMING AND SETUP
NOTE:
- DO NOT program a control module unless directed to by a service
procedure or a service bulletin. If the control module is not properly
configured with the correct calibration software, the control module will
not control all of the vehicle features properly.
- Ensure the programming tool is equipped with the latest software and
is
securely connected to the data link connector. If there is an interruption
during programming, programming failure or control module damage may
occur.
- Stable battery voltage is critical during programming. Any
fluctuation,
spiking, over voltage or loss of voltage will interrupt programming. When
required install the EL-49642 SPS Programming Support Tool to maintain
system voltage. If not available, connect a fully charged 12 V jumper or
booster pack disconnected from the AC voltage supply. DO NOT connect a
battery charger.
- Turn OFF or disable systems that may put a load on the vehicles
battery
such as; interior lights, exterior lights (including daytime running
lights),
HVAC, radio, etc.
- During the programming procedure, follow the SPS prompts for the
correct ignition switch position.
- Clear DTCs after programming is complete. Clearing powertrain DTCs
will
set the Inspection/Maintenance (I/M) system status indicators to NO.
