PINPOINT TEST AL: NO POWER TO THE DATA LINK CONNECTOR (DLC)

For circuit and connector information, refer to Wiring Diagrams Cell 14.

Normal Operation and Fault Symptoms

The diagnostic scan tool connects to the DLC to communicate with the Diag 1 and Diag 2 networks. The GWM acts as a gateway for communication between the Diag 1 and Diag 2 networks and the modules on the HS-CAN1, HS-CAN2, HS-CAN3, HS-CAN4 and MS-CAN. A loss of ground or a poor ground at the DLC may cause network faults when the diagnostic scan tool is connected. REFER TO: Communication Network - System Operation and Component Description (418-00 Module Communications Network, Description and Operation).

Possible Sources

Fuse
Wiring, terminals or connector
DLC
Diagnostic scan tool

Visual Inspection and Pre-checks

Make sure the BCM fuses 13 (7.5A) and 15 (10A) are good.

AL1 INSPECT DLC (DATA LINK CONNECTOR) PINS FOR DAMAGE

Ignition OFF.

NOTE: If the vehicle has one or more modules that become inoperative or exhibit observed symptoms when the scan tool is connected, this condition is likely caused by split ground terminals 4 and 5 at the DLC. An improperly grounded scan tool will disrupt network message traffic. Disconnect the diagnostic scan tool cable from the DLC.

Inspect the pins 4, 5 and 16 of the connector for spreading or damage using a flat probe with dimensions: width 1.5 mm x thickness 0.080 mm, Rotunda probe 300-08039 (purple).

Are there any pin fit or pin damage concerns with DLC pins 4, 5 and 16?

Yes
