-------------------------------------------------
P2 CHECK THE VOLTAGE TO THE SCAN TOOL VOLTAGE SUPPLY CIRCUIT FOR AN OPEN
-
Measure the voltage between the DLC C251-16, circuit SBP20 (GN/RD), harness side and ground.
-
Is the voltage greater than 10 volts?
Yes
GO to P3.
No
VERIFY the Smart Junction Box (SJB) fuse 20 (15A) 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.
-------------------------------------------------
P3 CHECK THE DLC GROUND CIRCUITS FOR AN OPEN
-
Disconnect: Negative Battery Cable.
-
Measure the resistance between the DLC C251-4, circuit GD134 (BK/VT), harness side and ground; and between the DLC C251-5, circuit GD134
(BK/VT), harness side and ground.
-
Are the resistances less than 5 ohms?
Yes
REPAIR the scan tool. CONNECT the negative battery cable. REPEAT the network test with the scan tool.
No
REPAIR the circuit in question. CONNECT the negative battery cable. REPEAT the network test with the scan tool.
