Pinpoint Test W: No Power To The Scan Tool
Refer to Wiring Diagram Set 14, Module Communications Network for schematic and connector information. See: Diagrams/Electrical
Diagrams/Diagrams By Number
Normal Operation
The scan tool is connected to the Data Link Connector (DLC) to communicate with the High Speed Controller Area Network (HS-CAN), the Medium
Speed Controller Area Network (MS-CAN) and the ISO 9141 communications networks. Voltage for the scan tool is provided by circuit SBP20
(GN/RD). Ground is provided by circuits GD115 (BK/GY) and GD113 (BK/YE).
This pinpoint test is intended to diagnose the following:
-
Fuse
-
Wiring, terminals or connectors
-
DLC
PINPOINT TEST W: NO POWER TO THE SCAN TOOL
NOTE: Most faults are due to connector and/or wiring concerns. Carry out a thorough inspection and verification before proceeding with the Pinpoint
Test. Failure to disconnect the battery when instructed will result in false resistance readings. See: Initial Inspection and Diagnostic
Overview/Communications Network/Inspection and Verification
-------------------------------------------------
W1 CHECK DLC PINS FOR DAMAGE
-
Disconnect the scan tool cable from the DLC.
-
Inspect the DLC pins 4, 5 and 16 for damage.
-
Are the DLC pins 4, 5 and 16 OK?
Yes
GO to W2.
No
REPAIR the DLC as necessary. CLEAR the DTCs. REPEAT the network test with the scan tool.
-------------------------------------------------
W2 CHECK THE DLC VOLTAGE SUPPLY CIRCUIT FOR AN OPEN
-
Measure the voltage between the DLC C251-16, circuit SBP20 (GN/RD), harness side and ground.
