Powertrain Modules - Engine and Transmission

ENGINE - POWERTRAIN CONTROL MODULE (PCM)

There are a variety of Engine (PCM) modules that are flash reprogrammable. Suggestions that are somewhat unique to each type will have comments. Prior to reprogramming a PCM, retrieve the module information and module type using your DRBII I�. PCM information is used by many modules. Be sure to check DIG's before and after performing all flash reprogramming event.

The DTC's associated with flash reprogramming generally relate to "lack of communication" with the other modules during the reprogramming session.

SBEC

Types:

SBEC, SBEC 2, SBEC 3, SBEC 3+, SBEC 3A, SBEC 3A+, and SBEC 3B

NOTE:
During recovery, if the DRBIII� is not seeing the key off, you may need to remove power (B+) to PCM by removing fuse(s) or disconnecting the PCM. When DRBIII� states to turn key ON, reconnect fuse or harness connection.

Abort Recovery Specifics:

^ Follow instructions on the DRBIII� for the module type. See table above.

^ Some SBEC 3A, SBEC 3A+ AND SBEC 3B may be in a state where they can not correctly identify a key cycle. In this case a Modified Key Cycle routine is required.

This state is present when the following message is displayed on the DRBIII(R): "Can not read Part Number. Did not see Key On or PCM/TCM Controller may not be flashable". When this occurs restart the flash session and when prompted to turn the ignition key to the LOCKED position, pull the fuse(s) that supply battery power to the module instead. When prompted to turn the key to the RUN position, replace the battery supply fuse(s) instead.

JTEC

Types:

^ JTEC, JTEC+

NOTE:
Viper ALL - Roll down windows especially Coupes before attempting a flash.

NOTE:
1999 WJ JTEC with Speed Proportional Steering module. Disconnect before and reconnect after the PCM flash reprogramming session. Also see Transmission.

Abort Recovery Specifics:

^ Follow DRBIII(R) prompts carefully.

NGC
Types:

^ NGC 1, NGC 2, and NGC 3

NOTE:
There are derivatives of NGC 3 that will be significant when reprogramming and or testing. NGC modules use one of the longest time spans for flash reprogramming (approximately 15 minutes). The NGCI and NGC3 controllers incorporate both an engine as well as a transmission controller in a common package. The NGC2 controller incorporates the engine controller and an Electronic Throttle Control (ETC) module in place of the TCM. All NGC controllers can be visually identified by noting its four (4) wiring connectors. On manual transmission applications and the NGC2, only 3 connectors may be populated with pins.

NOTE:
On certain vehicles, the ABS CAB module connector MUST be disconnected prior to performing this Repair Procedure. The CAB module and the PCM are connected at the same diagnostic connector pin (Pin # 9). Turn ignition switch to the OFF position, disconnect the CAB module connector, and reprogram the PCM per the Repair Procedure. When reprogramming is complete turn the ignition switch to the OFF position, connect the CAB module connector, and then check for DTC's. If the PCM becomes "locked" during reprogramming because the ABS CAB module connector was not disconnected, then the PCM may be recovered by following the procedure in this NOTE.

Abort Recovery Specifics:

^ Follow DRBIII(R) prompts carefully.

^ Power down the DRBIII(R) then cycle ignition before powering up the DRBIII(R) to attempt the flash.

CUMMINS

Types:

^ CM551 and CM84x series

NOTE:
Cummins flash reprogrammable PCMs are used on 1998.5 and newer Dodge Trucks.

Abort Recovery Specifics:

^ Follow DRBIII(R) prompts carefully. Model Year 2000 and earlier vehicles have one Engine Control Fuse to pull when prompted by the DRBIII(R). Model Year 2001 and later have two Engine Control Fuses (one 20 Amp and one 30 Amp) to pull when prompted by the DRBIII(R). The fuse(s) are located in the PDC and need to be pulled/removed, when prompted, for at least 10 seconds.

SIEMENS

Types:

^ SIM-70

NOTE:
The SIM-70 is currently used on BUX PL and PG vehicles with a 1.6L ONLY. Abort Recovery Specifics:

Follow DRBIII(R) prompts carefully.

BOSCH

Types:

^ EDC15V, EDC15-C5, and EDC16

NOTE:
While there have been other Bosch modules, the EDC15V is not flash reprogrammable.

Transmission controllers are usually flashed on the vehicle (since 1996).

Technicians may set the pinion factor on "NEW" modules either before or after flash reprogramming. Suggestions follow.

After flash reprogramming and before returning the vehicle to the customer, always perform a "QuickLearn" to the TCM.

EATX

Types:

^ EATX, EATX 2, EATX 3, EATX 3A, EATX 3B, EATX 4, and EATX 4A

NOTE:
Table shows which TCM was installed "as-built". Often TCMs are superseded by parts and or a service bulletin.

Abort Recovery Specifics:

^ 1999 - 2000 WJ and 2000 AN/DN using 4.7L engines the service replacement EATX4A part numbers 56041814AD and 56028227AH currently display a P/N read failed error after the flash is completed during PIN verification. This DOES NOT mean the flash failed. Check for the part number using DRBIII(R) in standalone mode. This exists only for the service replacement modules listed above. Flash reprogramming for OE modules flash and read the part number correctly. Follow DRBIII(R) prompts carefully.

NGC

Types:

^ NGC1, NGC2, NGC3

NOTE:
The NGC I1and NGC 3 have the EATX/XCORE and Engine modules combined. NGC 2 does not. Vehicles with automatic transmissions using NGC2 will use an EATX4A.

Abort Recovery Specifics:

^ Follow DRBIII(R) prompts carefully.

^ 2002 DR, 2002.5 DN, 2003 AN/DN and later with NGC have shown that in some instances the CAB controller may need to be disconnected when attempting to flash the NGC controller. (This should only be performed if an error occurs at the very beginning of the TCM flash portion.)

SIEMENS

Types:

^ EG552

NOTE:
EGS52 is used with the A580 automatic transmission WG Grand Cherokees with a 2.7L diesel engine (BUX), ZH Crossfire and VA Sprinter.

Abort Recovery Specifics:

^ Follow DRBIII(R) prompts carefully.

JTEC

Types:

^ JTEC,JTEC+

NOTE:
Except for the 45RFE, 545RFE, and AW4 automatic transmissions, the JTEC controller also provides transmission control functions on Dodge trucks and Jeep vehicles. Additionally, they are used on some Cummins equipped Dodge trucks with manual and automatic transmissions.

Abort Recovery Specifics:

^ Follow DRBIII(R) prompts carefully.

PRE 1996 EATX TRANSMISSION CONTROL MODULES

Prior to 1996 there was not a vehicle SCI communication wire going to the FWD EATX controller only to the PCM. Those vehicle TCMs only communicate to the DRBIII(R) using CCD communications.

For these FWD vehicles, use the CH5500 kit and CH7025 DIN cable when connecting those modules to the DRBIII(R) vehicle connector.

For 1992-1993 vehicles, the TCM modules were upgraded to MY1995 software. Because of this you will need to use the Yellow SuperCard2, CH8361,to set pinion factor or when using a "new" (superseded) TCM from parts as only the SuperCard2 properly sets the pinion factor on these updated modules.

Additionally, when flashing or installing P/Ns 4796121, 4796122, 4796123, or 4796124.

The wire from cavity 49 must be removed from the TCM connector, refer to service bulletin 18-24-95.
