No Module/Network Communication - No Power To The Diagnostic Tool

PINPOINT TEST 8 - NO MODULE/NETWORK COMMUNICATION - NO POWER TO DIAGNOSTIC TOOL

PINPOINT TEST 1		MODULE DOES NOT RESPOND TO THE DIAGNOSTIC TOOL - SMART JUNCTION BOX (SJB)
STEP	INSPECTION		ACTION
1	CHECK THE DIAGNOSTIC TOOL CONNECTOR Inspect the diagnostic tool pins for damage. Are the pins OK?	Yes	Go to step 2.
1		No	Repair the diagnostic tool connector. CARRY OUT the data link diagnostics test.
2	CHECK DATA LINK CONNECTOR (DLC) D-01 Inspect data link connector (DLC) D-01 pins for damage. Are the pins OK?	Yes	Go to step 3.
2		No	Repair the DLC D-01. CARRY OUT the data link diagnostics test.
3	CHECK THE VOLTAGE TO THE DLC D-01 CIRCUIT O Measure the voltage between the DLC D-01 pin 16, circuit O, harness side and ground. Is the voltage greater than 10 volts?	Yes	Go to step 4.
3		No	Repair the circuit. CARRY OUT the data link diagnostics test.
4	CHECK THE DLC GROUND CIRCUIT B AND CIRCUIT B Measure the resistance between the DLC D-01 pin 4, circuit B, harness side and ground; and between the DLC D-01 pin 5, circuit B, harness side and ground. Are the resistances less than 5 ohms?	Yes	Repair the diagnostic tool. CARRY OUT the data link diagnostics test.
4		No	Repair the circuit in question. CARRY OUT the data link diagnostics test.
