Pinpoint Test K: No Module/Network Communication - No Power To The Diagnostic Tool
WARNING: This page is about a different car, the 2005 Ford Pickup, 2005 Ford F550 Super Duty, 2005 Ford F450 Super Duty, and 2005 Ford Cab & Chassis. However, it is still accessible from the selected car via links, so may be relevant.
- K1 CHECK THE DIAGNOSTIC TOOL CONNECTOR FOR DAMAGE
- Inspect the diagnostic tool pins for damage.
- Are the pins OK?
- Yes : GO to K2.
- No : REPAIR the diagnostic tool connector as necessary. CARRY OUT the data link diagnostics test.
- K2 CHECK THE DATA LINK CONNECTOR (DLC) C251 FOR DAMAGE
- Inspect the DLC C251 pins for damage.
- Are the pins OK?
- Yes : GO to K3.
- No : REPAIR the DLC C251 as necessary. CARRY OUT the data link diagnostics test.
- K3 CHECK CIRCUIT 40 (LB/WH) FOR VOLTAGE
- Key in ON position.
- Measure the voltage between the DLC C251 pin 16, circuit 40 (LB/WH), harness side and ground.
- Is the voltage greater than 10 volts?
- Yes : GO to K4.
- No : REPAIR the circuit. CARRY OUT the data link diagnostics test.
- K4 CHECK CIRCUITS 57 (BK) AND 570 (BK/WH) FOR AN OPEN
- Measure the resistance between the DLC C251 pin 4, (BK), harness side and ground; and between the DLC 5, circuit 570 (BK/WH), harness side and ground.
- Are the resistances less than 5 ohms?
- Yes : REPAIR the diagnostic tool. CARRY OUT the data link diagnostics test.
- No : REPAIR the circuit in question. CARRY OUT the data link diagnostics test.
