Bulletin No: 01-030/02 Last Issued: 12/20/2002

Subject:PROGRAMMABLE PARAMETERS RESET FOR GEM/CTM

MODULES, ABS MODULE, OR PCM AFTER MODULE REPLACEMENT OR RE-PROGRAMMING WITH WDS OR NGS APPLICABLE MODEL(S)/VINS 1998 to 2002 Truck (All Models) DESCRIPTION

The GEM / CTM modules, ABS module and the PCM need to know accurate programmable parameters. Programmable parameters include: tire size,wheel diameter, axle size, axle ratio, and revolutions per mile (Rev/ Mile), and ABS type. This information is used by the modules to compute accuratevehicle speed. Additionally the modules need to know which ABS system the vehicle was built with (RWABS or 4WABS).

It is important to update the programmable parameters whenever the GEM / CTM modules, ABS module or PCM is replaced and whenever tire size,wheel diameter, axle size or axle ratio is changed. You should also confirm correct programmable parameters after performing module programming andre-programming.

If programmable parameters are not programmed, you may end up with DTC's that are difficult to diagnose or module communication errors. If theprogrammable parameters are incorrect, the vehicle systems will not operate as designed.

PCM replacement is done differently based on model year. Some vehicles require a Programmable Module Installation procedure (PMI). Other vehiclesrequire "Parameter Reset" procedure. The table identifies which years each procedure applies to. ABBREVIATIONS

Programmable Parameters = This data includes tire size, wheel diameter, axle size (7.5" or 8.8"), axle ratio, revs/mile, and ABS type. This information isprogrammed into the vehicle after build to make sure the correct options are programmed for diagnostics as well as the all vehicle speed related data.This assures that all control modules will recognize the correct vehicle speed.

GEM* = Generic Electronic Module. The GEM holds programmable parameters on vehicles with power equipment (power door locks, power windows,power mirrors, 4X4 etc.) from 1998 to 2000. CTM* = Central Timer Module. The CTM holds programmable parameters one vehicles without power equipment from 1998 to 2000.

PCM* = Powertrain Control Module. The PCM holds "Backup" programmable parameters for all trucks manufactured from 2001 on.

ABS = The Anti-lock Braking System module holds its own programmable parameters for ABS system operation. There are 2-types of ABS: 4WABS =4-Wheel Anti-lock Braking System and RWABS = Rear Wheel Anti-lock Braking System. * = As of 2001 all vehicles regardless of power equipment, have a GEM and all programmable parameters are stored in the PCM.

The process of setting programmable parameters is considered a normal part of module replacement and is already included in the labor operation forthat process.

:NOTE

Obtain the following information from the vehicle:

- Tire Size (on tire sidewall)

- Axle ratio and Axle Diameter (found on tag on axle housing)

Page 34

8. Select "Tire Size". Press Trigger. Use the keypad and the table to enter the REVS/Mile.

:NOTE

Example: if revs/mile is 680, enter 00680.

9. Highlight "Tone Ring Size", press TRIGGER.

- Select the correct size using the table

10. Select "Option", Press TRIGGER

11. Select "ABS system", Press TRIGGER

12. Select "Vehicle" - it should indicate "B-=Series", Press TRIGGER.

13. Message "Module Configuration Complete" is displayed. Press TRIGGER.

14. Confirm all entries and select "Done"

15. Now you must configure the GEM or CTM.

Configuration Principles of Operation

Generic Electronic Module/Central Timer Module: Description and OperationModule Configuration Principles of Operation

Newly released modules will require configuration after being installed on the vehicle.NOTE:

There are customer preference items that can or need to be configured on this vehicle. These are items that the customer may or may not want to haveenabled. Typically, customer preference items can be toggled on or off by the use of the NGS Tester. You may need to ask the customer whichpreferences they had enabled prior to installation of the new module.

To carry out the customer configuration process, use the NGS Tester and the latest program card. Refer to the Customer Preference Index for modules onthe vehicle that have customer preference items. Configure the items as needed with the NGS Tester

Configuration Principles of Operation > Page 60

Generic Electronic Module/Central Timer Module: Description and OperationGeneric Electronic Module (GEM) / Central Timer Module (CTM) GEM/CTM System Outline

- The GEM is equipped on vehicles with four-wheel drive or with power windows.

- The CTM is equipped on vehicles with two-wheel drive or without power windows.

The GEM/CTM control system has two modes of operation:-

Normal mode.

- Diagnostic mode.

- When the GEM/CTM is not energizing a load, the GEM/CTM can only detect open circuit and short to ground faults.

- When energizing a load, the GEM/CTM can only detect short to power faults.

Normal Operating Mode

- The normal operation of the GEM/CTM can detect errors.

An integral part of the normal GEM/CTM operation is the continuous diagnostic capability. Continuous diagnostics detects errors and changes theGEM/CTM control strategy.

- There is no warning light for the GEM/CTM; therefore, a DTC concern will direct the technician to the GEM/CTM.

- Examples of faults that may be detected during normal operation include:

- GEM/CTM continuous self-test.

- Output driver monitoring (open circuit/short to GND, short to power).

- Illogical combinations of input signals.

Wiper/Washer Subsystem

The GEM/CTM controls five modes of operation for the wiper. These modes are active only when the ignition switch is in the RUN or ACCposition.

- The GEM/CTM responds to the windshield wiper control commands by interpreting inputs from the multi-function switch.

- The GEM/CTM relay drivers control the wiper HI/LO relay, wiper PARK/RUN relay and the washer pump relay.

Warning Lights and Audible Warning Devices Subsystem

- The GEM/CTM controls all audible warning devices and warning lights.

The GEM/CTM performs a prove out on all GEM/CTM-controlled indicator/warning bulbs (except the seat belt and door ajar indicator lights) byturning on the bulb for after the ignition is turned to run.two seconds

Battery Saver Subsystem

- The battery saver feature removes extended interior lamp power drains to the battery.

The GEM/CTM will keep power available for all interior lights for after the ignition switch is turned .45 minutes OFF

The battery saver is reset by:-

Receiving an illuminated entry request.

- Activating a door ajar warning switch.

- Starting the vehicle.

- Turning the ignition to RUN or ACC.

Interior Lamp Subsystem

- The GEM/CTM illuminates the interior courtesy lamps when any door is set ajar or is opened.

All interior courtesy lamps are turned off when any of the following occurs:-

All doors are closed and illuminated entry feature is not active.

- The ignition switch is turned to RUN.

Vehicle speed is over .5 mph (8 kmh mph)

Illuminated Entry Subsystem

- The illuminated entry feature (GEM only) activates the interior lamps.

- The GEM illuminates the interior lamps when an unlock signal is received from the RAP module.

Information > Description and Operation > Module Configuration Principles of Operation > Page 61

B4000 SE Cab Plus 4 4WD V6-4.0L OHV (2000)

Illuminated entry inputs are:-RAP illuminated entry request (grounded pulse of varying length).

- Ignition in RUN (battery voltage on both the RUN and RUN/ACC inputs).

- Illuminated entry output is:

- Interior lamp relay coil output.

- Grounded when activated.

- Open circuit when deactivated.

- The RAP module sends a signal to the GEM to turn the illuminated entry on or off.

- Illuminated entry will be canceled if:

have elapsed since the illuminated entry feature was activated and the courtesy lamp feature is not activated.25 seconds

- If the GEM receives a request from the RAP and the courtesy lamp feature is not activated.

- If the ignition is in the RUN or START position and the courtesy lamp feature is not activated. Illuminated entry inputs are:

Page 100

- Ignition switch in the key-in, ACCY and RUN positions.

- RAP module illuminated entry request.

Power Window Subsystem

The GEM/CTM provides temporary power to the power windows for after the ignition is turned from RUN to .ten minutes OFF

- If either front door is opened during this period, the power window relay will be de-energized.

- The GEM controls the one-touch down window feature.
