Hello everyone.. I have an 08 3500 sprinter. Can someone please give me an idea as to the location of the DLC ???? Can't locate this one...lol

 

The Data Link Connector (DLC) (1) is a 16-way molded plastic connector insulator with a hinged molded plastic cover. This connector is located on the left cowl side inner trim cover below the driver side outboard end of the instrument panel (2), inboard of the inside hood release lever (4).
The DLC connector insulator is retained to the upper edge of the fuse and relay box (3) opening of the cowl side inner trim cover by two screws and is concealed beneath the removable access panel for the fuse and relay box.

 

thanks Tizzy.. I thought that it was there but doesn't look like a normal data link connector sitting up there

 

I have a 2008 dodge sprinter n I have a code u0155 can some 1 help ma with that

 

U0155-LOST COMMUNICATION WITH CLUSTER/CCN
For a complete wiring diagram, refer to the Wiring Information.

Theory of Operation
The Transmission Control Module (TCM) receives information from the Engine, Anti-lock Brake System, and the Electronic Gear Shift control modules over the CAN C bus. The CAN C bus is a high speed communication bus that allows real time control capability between various controllers. Most messages are sent every 20 mSec, this means critical information can be shared between multiple controllers almost instantaneously. The CAN C bus is a two wire bus with a CAN (+) and a CAN (-) circuit. To reduce the potential of radio and other electrical noise interference, the CAN Bus circuit wiring is manufactured using a twisted pair configuration within the electrical wiring harness.

When Monitored:
Continuously with the ignition on.

Set Condition:
The DTC will set if a valid CAN ID was not received in the required time from the Cluster/CCN.


Possible Causes
TRANSMISSION CONTROL MODULE (TCM)

Always perform the Pre-Diagnostic Troubleshooting procedure before proceeding. (Refer to 28 - DTC-Based Diagnostics/MODULE, Transmission Control (TCM) - Standard Procedure).



1. CHECK FOR CAN C BUS COMMUNICATION DTCS


--------------------------------------------------------------------------------
1. With the scan tool, check for CAN DTCs.


Is DTC U0001-CAN C BUS DTC or U0155-LOST COMMUNICATION WITH CLUSTER/CCN set?

Yes

Refer to DTC Based Diagnostics and perform the appropriate diagnostic procedure. Perform the diagnostic procedure for U0001-CAN C BUS first if it is present.
Perform the NAG1 TRANSMISSION VERIFICATION TEST. (Refer to 28 - DTC-Based Diagnostics/MODULE, Transmission Control (TCM) - Standard Procedure).

No

2. CHECK IF THE DTC IS CURRENT


--------------------------------------------------------------------------------


NOTE: When the Transmission Control Module (TCM) detects and stores a DTC, the TCM also stores the vehicles operating conditions under which the DTC originally set. This information is located in the scan tool under Environmental Data. Before erasing any stored DTCs, record any available data to assist in duplicating the conditions in which the DTC originally set.
1. Ignition on, engine not running.
2. With the scan tool, erase Transmission DTCs.
3. Using the Environmental Data recorded earlier, try to duplicate the conditions in which the DTC originally set. It may be necessary to test drive the vehicle.
4. With the scan tool, read Transmission DTCs.


Did the DTC U0155-LOST COMMUNICATION WITH CLUSTER/CCN reset?

Yes

Using the schematics as a guide, check the Transmission Control Module (TCM) pins, terminals, and connectors for corrosion, damage, or terminal push out. Pay particular attention to all power and ground circuits. If no problems are found, replace and program the TCM in accordance with the Service Information.
Perform the NAG1 TRANSMISSION VERIFICATION TEST. (Refer to 28 - DTC-Based Diagnostics/MODULE, Transmission Control (TCM) - Standard Procedure).

No

3. CHECK THE WIRING AND CONNECTORS


--------------------------------------------------------------------------------
1. The conditions necessary to set this DTC are not present at this time.
2. Using the schematics as a guide, inspect the wiring and connectors specific to this circuit.
3. Wiggle the wiring and connectors while checking for any possible open or shorted circuits.
4. Check for any Service Information Tune-ups or Technical Service Bulletins that may apply.


Were there any problems found?

Yes

Repair as necessary.
Perform the NAG1 TRANSMISSION VERIFICATION TEST. (Refer to 28 - DTC-Based Diagnostics/MODULE, Transmission Control (TCM) - Standard Procedure).

No

Test Complete.
