## NHTSA's summary

ServiceNews Article \- Troubleshooting DTCs for a solenoid or motor power supply circuit failure? Keep in mind that even though the control unit activates these components, the power supplied may come from a dedicated circuit and its own separate fuse. This is most commonly overlooked when troubleshooting transmission or VTEC solenoid circuits. If the troubleshooting leads you to replace a control unit, make sure you understand and inspect all the power supplies to that control unit first.
