What does the code P0600 mean on a Dodge Grand Caravan and how can it be cleared?

The reason of Dodge Grand Caravan P0600 OBD-II Engine Trouble Code is P0600 Loss of Serial Communication Link. To clear the code take it to a auto zone and see if they will flash it what that does is remove the code. But it will come back on as the problem needs to be fixed.

Fixes for non-communicating OBD II port and nonworking trunk release button on driver door panel?

What pins did your friend jump in the DLC ,2 an 4 ? they don't call it ALDL any more ! Does the vehicle start an run ?
The data link connector (DLC) is a standardized 16 cavity connector. Connector design and location is dictated by an industry wide standard, and is required to provide the following:
Scan tool power battery positive voltage at terminal 16.

Scan tool power ground at terminal 4.

Common signal ground at terminal 5.

Class 2 signal at terminal 2.

I wonder how many friends out there mess up other friends vehicles from stuff they see on the internet . When are you people going to learn , your messing with complex electronics !!!!! He shorted out the class 2 serial data communication network !
Do you know what this is ? if not you need to take to your local GM Mr. goodwrench !
Class 2 Serial Data Link
The data link is configured as a ring with discrete lines entering and leaving each module. This allows communications to the modules on the ring if one of the two discrete circuits is open.
A total list of the control modules on the Class 2 Serial Data Line can include the following:
Dash Integration Module (DIM)

Driver Door Module (DDM)

Electronic Brake Control Module (EBCM)

Head Up Display (HUD) w/UV6

HVAC Control Module w/C67

Inflatable Restraint Sensing and Diagnostic Module (SDM)

Instrument Panel Cluster (IPC)

Instrument Panel Integration Module (IPM) w/CJ2

Memory Seat Module (MSM) w/A45

Powertrain Control Module (PCM)


Rear Integration Module (RIM)

Remote Control Door Lock Receiver (RCDLR)

Remote Playback Device - CD Changer w/U1S

Theft Deterrent Control Module

Vehicle Interface Unit (VIU) w/UE1

Power door serial data does not communicate with the scan tool via the DLC. Power door serial data information is interpreted by the driver door module (DDM) and transmitted on the Class 2 data link by the DDM.
Power door serial data is used for serial data communication between the four door modules as well as the driver door switch assembly (DDSA
Scan Tool Does Not Communicate with Class 2 Device
Modules connected to the class 2 serial data circuit monitor for serial data communications during normal vehicle operation. Operating information and commands are exchanged among the modules. Connecting a scan tool to the DLC allows communication with the modules for diagnostic purposes.
The engine will not start when there is a total malfunction of the class 2 serial data circuit while the engine is not running.
Test Description
The numbers below refer to the step numbers on the diagnostic table.

  1. A partial malfunction in the class 2 serial data circuit uses a different procedure from a total malfunction of the class 2 serial data circuit.

  2. The DTC U1300, U1301, and U1305 may be retrieved with a history status. These DTCs are not the cause of the present condition.

  3. A State of Health DTC with a history status may be present along with a U1000 or a U1255 with a current status. This indicates that the malfunction occurred when the ignition was on.

How do I fix a serial 2 data link malfunction on a 4 cylinder 99 sunfire

Hey John ! how's it going ? How do you know you have a class 2 data bus problem ? Need some more info ! Do you have a scan tool ? Can't communicate with the PCM ? Have a check engine light on ?
You may access 2 data lines with the scan tool. The serial data line UART (circuit 800) allows the following components to communicate via serial data:
The scan tool

The powertrain control module (PCM)

The instrument panel cluster

The sensing diagnostic module (SDM)

The electronic brake control module (EBCM)

The serial data line class 2 (circuit 1807) allows the scan tool to access directly the PCM in order to read emissions-related information. The scan tool gains access to both data lines through the data link connector (DLC). You may then monitor or control system operations for diagnostic purposes.
