GO to R3.
No
Go To Pinpoint Test Q. See: Pinpoint Test Q: No Power To The Scan Tool
-------------------------------------------------
R3 CHECK THE HS-CAN (+) AND HS-CAN (-) CIRCUITS FOR A SHORT TO GROUND
-
Measure the resistance between the DLC C251-6, circuit VDB04 (WH/BU), harness side and ground; and between the DLC C251-14, circuit
VDB05 (WH), harness side and ground.
-
Are the resistances greater than 1,000 ohms?
Yes
GO to R4.
No
Go To Pinpoint Test Q. See: Pinpoint Test Q: No Power To The Scan Tool
-------------------------------------------------
R4 CHECK THE HS-CAN (+) AND HS-CAN (-) CIRCUITS FOR A SHORT TO VOLTAGE
-
Connect the battery ground cable.
-
Ignition ON.
-
Measure the voltage between the DLC C251-6, circuit VDB04 (WH/BU), harness side and ground; and between the DLC C251-14, circuit
VDB05 (WH), harness side and ground.
-
Is the voltage greater than 6 volts?
Yes
REPAIR the circuit. CLEAR the DTCs. REPEAT the network test with the scan tool.
No
GO to R5.
-------------------------------------------------
R5 CHECK FOR RESTORED COMMUNICATION WITH THE PCM DISABLED
NOTE: An integrated diagnostic system (IDS) session must be established prior to disabling the PCM in this test step. If the PCM has failed
communication during multiple attempts to identify the vehicle, first identify the vehicle manually by entering a PCM part number, calibration number or
tear tag when prompted by IDS.
NOTE: When a vehicle is manually identified by a PCM part number, calibration number or tear tag, the IDS will not automatically run a network test.
The network test must be manually selected and run.
NOTE: When re-running the network test, the network test application must be first closed or the screen display will revert back to the prior run network
test results.
