left subframe. See Fig. 69 . For Passat see, Fig. 70 . Start engine. Brake Vacuum Pump (V192) must run
briefly. If brake vacuum pump does not run, go to next step. If brake vacuum pump runs briefly, brake
vacuum pump is okay. Visually check brake vacuum pump harness connector and wiring for damage
(possibly intermittent), erase DTC memory. Perform ECM relearn procedure. See TEST DRIVE
RELEARN PROCEDURE . If DTC for Brake Vacuum Pump (V192) does not reset, test is complete.
2. Check Brake Vacuum Pump (V192) wiring for open or short circuits. See appropriate WIRING
DIAGRAM under ENGINE PERFORMANCE in SYSTEM WIRING DIAGRAMS. Repair as necessary.
After repairs, erase DTC memory. Verify repair. Test is complete. Perform ECM relearn procedure. See

is off.
Test Procedure
Using DVOM, check power supply and ground to Fuel Pump Relay. See Fig. 38 . See appropriate WIRING
DIAGRAM under ENGINE PERFORMANCE in SYSTEM WIRING DIAGRAMS. Check resistance of Fuel
Pump Relay wiring. See Fig. 38 . See appropriate WIRING DIAGRAM under ENGINE PERFORMANCE in
SYSTEM WIRING DIAGRAMS. Resistance should be a maximum of 1.5 ohms for each reading. Check Fuel
Pump Relay wiring for short circuits to one another, and for short circuits to B+ and ground. See Fig. 38 . See
appropriate WIRING DIAGRAM under ENGINE PERFORMANCE in SYSTEM WIRING DIAGRAMS. If
resistance, voltage and ground supply are okay and no short circuits are present, replace faulty Fuel Pump Relay
(J17). If resistance and/or voltage or ground supply are not okay or a short circuit is present, repair as necessary.
Erase DTC memory. Test is complete. Perform ECM relearn procedure. See TEST DRIVE RELEARN
PROCEDURE .
