TEST 2: Making Sure The EVRV Solenoid Is Getting 12 Volts
The EVRV solenoid receives 12 Volts from the pink with black stripe (PNK/BLK) wire of the solenoid's 3-wire connector.
The PNK/BLK wire connects to the terminal labeled with the letter A in the illustration above.
We'll perform a simple multimeter voltage test to check for the presence of 10 to 12 Volts in the PNK/BLK wire.
These are the test steps:
- 1
Disconnect the EVRV solenoid from its connector.
- 2
Place your multimeter in Volts DC mode.
- 3
Connect the black multimeter test lead to the battery negative (-) terminal.
- 4
Turn the key to the ON position but don't crank or start the engine.
- 5
With the red multimeter test lead, probe the terminal labeled with the letter A (see illustration above).
- 6
Your multimeter should read 10 to 12 Volts DC.
Let's interpret your test result:
CASE 1: Terminal A is delivering 10 to 12 Volts DC. This is the correct test result.
The next step is to make sure that terminal D is delivering chassis Ground to the solenoid. Go to: TEST 3: Making Sure The EVRV Solenoid Is Getting Ground.
CASE 2: Terminal A IS NOT delivering 10 to 12 Volts DC. Without 12 Volts, the EVRV solenoid will not function.
Although its beyond the scope of this tutorial, your next step is to find out why these 12 Volts are missing and restore them.
TEST 3: Making Sure The EVRV Solenoid Is Getting Ground
The EVRV solenoid receives chassis Ground from the black (BLK) wire of the solenoid's 3-wire connector.
The BLK wire connects to the terminal labeled with the letter D in the illustration above.
We'll perform a simple multimeter voltage test to check for the presence of Ground in the BLK wire.
Let's begin:
- 1
Disconnect the EVRV solenoid from its electrical connector.
- 2
Place your multimeter in Volts DC mode.
- 3
Connect the red multimeter test lead to the battery positive (+) terminal.
- 4
With the black multimeter test lead, probe the terminal labeled with the letter D.
- 5
Your multimeter should read 10 to 12 Volts.
NOTE: No need to turn the key to the ON position, since this is a chassis Ground and is available at all times.
Let's take a look at what your test results mean:
CASE 1: The multimeter registered 10 to 12 Volts. This is the correct test result and it indicates that terminal D is supplying Ground to the EVRV solenoid.
Your next step is to go to: TEST 4: Is The EVRV Solenoid Stuck Open? PART 1.
CASE 2: The multimeter DID NOT register 10 to 12 Volts. This test result tells you that the wire that connects to terminal D is not supplying Ground.
The most likely cause of this missing Ground is an open-circuit problem in the black with white stripe wire. Your next step is to resolve the issue causing this lack of chassis Ground and retest.
