   The wiring and connections to solenoid valve SV1

2. 2

   The integrity of the circuit associated with solenoid valve SV1

3. 3

   The behavior of the component identified by this code

1. 1

   Inspect the wiring and connections to solenoid valve SV1

   Check for loose, damaged, or corroded connections that may cause unintended voltage presence.

2. 2

   Test the circuit associated with solenoid valve SV1

   Use a multimeter to verify the presence of voltage and ensure it aligns with expected behavior when the driver is not active.

3. 3

   Verify the operation of the component identified by this code

   Follow the service manual procedures to confirm the functionality of the affected circuit.
