Pinpoint Test E: Transfer Case Solenoid Circuit Tests

  1. E1: TRANSFER CASE WIRING HARNESS AND SOLENOID LOW RESISTANCE 
    1. Set the ignition to off.
    2. Disconnect the largest wiring harness connector from the transfer case control module.
    3. Connect an ohm-meter to terminal 12 and terminal 9 of the transfer case control module wiring harness connector.
    4. Measure the resistance.

    Is the measured resistance less than 0.2 Ω?

    • Yes  : Resistance too low. GO to  E2.
    • No  : Resistance not too low. GO to  E3.
  2. E2: TRANSFER CASE SOLENOID LOW RESISTANCE 
    1. Disconnect the wiring harness connector from the transfer case solenoid.
    2. Connect an ohm-meter to terminal 1 and terminal 2 of the transfer case solenoid.
    3. Measure the resistance.

    Is the measured resistance less than 0.2 Ω?

    • Yes  : Resistance too low. Install a new transfer case solenoid.
    • No  : Resistance not too low. Check the transfer case solenoid wiring harness for short circuit between the wires. Repair the wiring harness as necessary.
  3. E3: TRANSFER CASE WIRING HARNESS AND SOLENOID HIGH RESISTANCE 
    1. Connect an ohm-meter to terminal 12 and terminal 9 of the transfer case control module wiring harness connector.
    2. Measure the resistance.

    Is the measured resistance greater than 10 Ω?

    • Yes  : Resistance too high. GO to  E4.
    • No  : Resistance not too high. GO to  E5.
  4. E4: TRANSFER CASE SOLENOID HIGH RESISTANCE 
    1. Disconnect the wiring harness connector from the transfer case solenoid.
    2. Connect an ohm-meter to terminal 1 and terminal 2 of the transfer case solenoid.
    3. Measure the resistance.

    Is the measured resistance greater than 10 Ω?

    • Yes  : Resistance too high. Install a new transfer case solenoid.
    • No  : Resistance not too high. Check the transfer case solenoid wiring harness for open circuit, high resistance. Repair the wiring harness as necessary.
  5. E5: TRANSFER CASE WIRING HARNESS AND SOLENOID SHORT CIRCUIT TO GROUND 
    1. Connect an ohm-meter to terminal 12 of the transfer case control module wiring harness connector and ground.
    2. Measure the resistance.

    Is the measured resistance infinitely high (open circuit)?

    • Yes  : No short circuit to ground. No fault found.
    • No  : Short circuit to ground. GO to  E6.
    • E6: TRANSFER CASE SOLENOID SHORT CIRCUIT TO GROUND 
    1. Disconnect the wiring harness connector from the transfer case solenoid.
    2. Connect an ohm-meter to terminal 12 of the transfer case control module wiring harness connector and ground.
    3. Measure the resistance.

    Is the measured resistance infinitely high (open circuit)?

    • Yes  : Short circuit to ground. Install a new transfer case solenoid.
    • No  : No short circuit to ground. Check the transfer case solenoid wiring harness for short circuit to ground. Repair the wiring harness as necessary.
