3. Inspect VSV for proper power and ground circuits.
Perform the following checks with the Canister Pump Module Connector connected and back probe the pins to obtain the readings.
A. Check for voltage between Pin 9 (VLVB) and Chassis Ground. With IG ON voltage should read between 9 V and 14 V
^
YES - Proceed to next step (3B).
^
NO - This TSB does NOT apply - inspect and repair wiring.
B. Check for voltage between pin 8 (VGND) and Chassis Ground. With IG ON voltage should read between 9 V and 14 V
^
YES - Proceed to next step (3C).
^
NO - Vent Valve is open - proceed to step 4.
C. Using TIS Techstream activate the VSV and check voltage between pin 8 (VGND) and Chassis Ground.
Powertrain > Engine > Active Test > Activate the VSV for Vent Valve
^
9 V - 14 V present - This TSB does NOT apply - inspect and repair wiring. < 1 V present - Proceed to step 4.
