TEST STEP ACTION TO TAKE
•
Is the voltage greater than 0 volts?
No = GO to E8.
E8 CHECK CIRCUIT 70 (LB/W) FOR SHORT TO GROUND
•
With key ON, measure the resistance between pin 7 (LB/W wire) and Yes = REPAIR the LB/W wire
pin 5 (BK/W wire) on DLC C209. between DLC C209 and
S2987 for an open.
•
Is the resistance greater than 10,000 ohms?
No = REPAIR the LB/W wire.
PINPOINT TEST F: NO MODULE/NETWORK COMMUNICATION — SCP LINK
