No Module/Network Communication - Controller Area Network (Can)

PINPOINT TEST 5 - NO MODULE/NETWORK COMMUNICATION - CONTROLLER AREA NETWORK (CAN)

PINPOINT TEST 1		MODULE DOES NOT RESPOND TO THE DIAGNOSTIC TOOL - SMART JUNCTION BOX (SJB)
STEP	INSPECTION		ACTION
1	CHECK THE DLC D-01 FOR DAMAGE Key OFF. Inspect the DLC D-01 for damage. Is the DLC D-01 OK?	Yes	Go to step 2.
1		No	Repair the DLC D-01. Carry out the data link diagnostics test. See DATA LINK DIAGNOSTICS TEST .
2	CHECK THE INSTRUMENT CLUSTER 0922-101 FOR DAMAGE Disconnect: Instrument Cluster 0922-101. Inspect the instrument cluster 0922-101 connector for damage. Is the instrument cluster 0922-101 connector OK?	Yes	Go to step 3.
2		No	Repair the instrument cluster 0922-101. Carry out the data link diagnostics test. See DATA LINK DIAGNOSTICS TEST .
3	CHECK CIRCUITS W/LG AND P/LG BETWEEN THE INSTRUMENT CLUSTER 0922-101 AND THE DLC D-01 FOR AN OPEN Measure the resistance between the DLC D-01 pin 6, circuit W/LG, harness side and the instrument cluster 0922-101 pin 1, circuit W/LG, harness side. Measure the resistance between the DLC D-01 pin 14, circuit P/LG, harness side and the instrument cluster 0922-101 pin 2, circuit P/LG, harness side. Are the resistances less than 5 ohms?	Yes	Go to step 4.
3		No	Repair the circuit in question. Carry out the data link diagnostics test. See DATA LINK DIAGNOSTICS TEST .
4	CHECK THE CAN CIRCUITS FOR A SHORT TO GROUND Measure the resistance between the DLC D-01 pin 6, circuit W/LG, harness side and ground; and between the DLC D-01 pin 14, circuit P/LG, harness side and ground. Are the resistances greater than 10,000 ohms?	Yes	Go to step 5.
4		No	Repair the circuit in question. Carry out the data link diagnostics test. See DATA LINK DIAGNOSTICS TEST .
5	CHECK THE CAN CIRCUITS FOR A SHORT TO POWER Key ON. Measure the voltage between the DLC D-01 pin 6, circuit W/LG, harness side and ground; and between the DLC D-01 pin 14, circuit P/LG, harness side and ground. Is any voltage indicated?	Yes	Repair the circuit in question. Carry out the data link diagnostics test. See DATA LINK DIAGNOSTICS TEST .
5		No	Go to step 6.
6	CHECK FOR CORRECT INSTRUMENT CLUSTER OPERATION Disconnect all the instrument cluster connectors. Check for: corrosion pushed-out pins Connect all the instrument cluster connectors and make sure they seat correctly. Operate the system and verify the concern is still present. Is the concern still present?	Yes	Install a new instrument cluster. See INSTRUMENT CLUSTER REMOVAL/INSTALLATION . Carry out the data link diagnostics test. See DATA LINK DIAGNOSTICS TEST .
6		No	The system is operating correctly at this time. The concern may have been caused by a loose or corroded connector. Clear the DTCs. REPEAT the self-test. Carry out the data link diagnostics test. See DATA LINK DIAGNOSTICS TEST .
