Neon L4-2.0L SOHC (1995)
And Reprogram
FAILURE CODE:
FM - Flash Module
Repair Procedure
This repair involves cleaning or replacing the positive battery cable, replacing the PCM on early built vehicles and selectively erasing and
reprogramming the Powertrain Control Module (PCM) with new software (calibration changes).
Positive Battery Cable Replacement
1.
Record preset radio settings.
2.
With the ignition key in the OFF position, disconnect the negative battery terminal.
3.
Disconnect the positive battery terminal and remove and discard the entire cable assembly.
4.
Install the new positive battery cable double eyelet to the power distribution center (PDC). Torque each nut to 35 in.lb. (4 Nm).
5.
Install the bolt/stud to the starter cable eyelet with the flats of the starter cable aligned with the flats on the bolt. Torque to 105 in.lbs. (12 Nm).
6.
Clean both battery posts and inside of negative terminal.
7.
Install the positive battery terminal and then the negative.
CAUTION:
INSURE THAT THE TERMINALS ARE INSTALLED NO HIGHER THAN FLUSH WITH THE POSTS. THIS WILL INSURE THAT THE
THERMOGUARD WILL SNAP TOGETHER PROPERLY.
8.
Torque each terminal to 7.4 Nm (65 in.lbs.) and coat the top of the positive terminal with grease.
NOTE:
TURN THE IGNITION KEY TO THE ON POSITION AND DO NOT START THE ENGINE FOR TWO TO THREE SECONDS. THIS WILL
ALLOW THE IAC TO POSITION ITSELF AND PREVENT STALLING.
9.
Verify proper charging system operation before proceeding.
10.
Reset radio preset recorded in step 1.
Powertrain Control Module Flash Procedure
1.
If the vehicle was built prior to August 1,1994 (MDH 08-01-XX) replace the PCM before proceeding.
2.
Connect the MDS (Mopar Diagnostic System) and DRB III (Scan Tool) to the vehicle and power them up.
3.
Use the arrow keys and select # 2 MDS DIAGNOSTICS on the DRB III MAIN MENU Screen.
4.
Use the arrow keys and select DIAGNOSTIC MENU on the MDS, then press NEXT MENU.
5.
Use the arrow keys and select VEHICLE CONTROLLER PROGRAMMING on the MDS, then press NEXT MENU.
6.
Use the arrow keys and select PROGRAMMING OF ALL OTHER CONTROLLERS USING MDS & DRBIII on the MDS, then press NEXT
MENU.
7.
Follow the steps presented on the MDS and DRB III which will allow the DRB III to obtain the current part number of the PCM.
8.
The MDS will display the part number of the PCM on the vehicle and the appropriate replacement part number, then press NEXT MENU to begin
programming.
If the PCM on the vehicle has already been updated or programmed, a NO UPDATES AVAILABLE message will be displayed. Check the part number
of the PCM on the vehicle and compare it to the part number displayed. If the PCM has already been updated, then another condition exists that will
require further diagnosis and repair.
9.
The MDS and DRB III will prompt for any operator action needed during the remainder of the programming process.
NOTE:
THE FOLLOWING STEPS ARE REQUIRED BY LAW.
