Normal Operation
The scan tool is connected to the Data Link Connector (DLC) to communicate with the High Speed Controller Area Network (HS-CAN) and the
Medium Speed Controller Area Network (MS-CAN) communications networks. Voltage for the scan tool is provided by circuit SBP20 (GN/RD).
Ground is provided by circuits GD115 (BK/GY) and GD116 (BK/VT).
This pinpoint test is intended to diagnose the following:
-
Fuse
-
Wiring, terminals or connectors
-
DLC
-
Scan tool
PINPOINT TEST S: NO POWER TO THE SCAN TOOL
