DIAGNOSTIC CODE 5-3 1. Connect a jumper between whichever pin did not show continuity in Test 2 (either pin B1 or B2), on the J1A connector, and J1B connector pin P2.
Test 8
2. Check for continuity from Deutsch pin G, on the pump end of the harness, to a good ground.
1. With the ignition key in the OFF position, reconnect the V-MAC II connectors.
If there is continuity, repair the open in the actuator MINUS [−] line which did not show continuity in Test 2 (A2 or B3 on the J1A connector). Retest to be sure the problem has been corrected. If there is no continuity, select another chassis ground. If there is still no continuity, repair the actuator PLUS [+] line which did not show continuity in Test 2 (B1 or B2 on the J1A connector). Retest to be sure the problem has been corrected.
Checking for a defective V-MAC II module or loose connector
2. Turn the ignition key to the ON position.
If code 5-3 is still active, check the V-MAC II module and connector for dirt, loose or broken pins, or repairable damage. If no problems are evident, replace the V-MAC II module. Retest to be sure the problem has been corrected. If code 5-3 is not active, the procedures have corrected the problem. Check all connectors to ensure proper connections.
