PINPOINT TEST V: 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. See: Initial Inspection and Diagnostic Overview/Module Communications Network/Inspection and Verification
NOTE: Failure to disconnect the battery when instructed will result in false resistance readings. Refer to Battery.
-------------------------------------------------
V1 CHECK THE DLC PINS FOR DAMAGE
-
Disconnect the scan tool cable from the DLC.
-
Inspect DLC pins 4, 5 and 16 for damage.
-
Are DLC pins 4, 5 and 16 OK?
Yes
GO to V2.
No
REPAIR the DLC as necessary. CLEAR the DTCs. REPEAT the network test with the scan tool.
-------------------------------------------------
V2 CHECK THE DLC VOLTAGE SUPPLY CIRCUIT FOR AN OPEN
-
Measure the voltage between the DLC C251-16, circuit SBP04 (GN/RD), harness side and ground.
-
Is the voltage greater than 10 volts?
Yes
GO to V3.
No
VERIFY the Smart Junction Box (SJB) fuse 4 (10A) is OK. If OK, REPAIR the circuit. If not OK, REFER to the Wiring Diagrams to identify the
possible causes of the circuit short. REPEAT the network test with the scan tool. See: Diagrams/Electrical Diagrams/Diagrams By Number

V3 CHECK THE DLC GROUND CIRCUITS FOR AN OPEN
-
Disconnect: Negative Battery Cable.
-
Measure the resistance between the DLC C251-5, circuit GD138 (BK/WH), harness side and ground; and between the DLC C251-4, circuit
GD138 (BK/WH), harness side and ground.
