Safety Warning
DIY auto repair can cause serious injury, fire, or vehicle damage. These guides are for informational purposes only. Always follow OEM torque specs, wear PPE, and consult a certified mechanic if you are unsure. You are solely responsible for your safety.
Self Shut Down (SSD) Mode
After the ignition switch is turned to ACC (I) or to LOCK (0), the PCM stays on for up to an hour. If a PCM connector is disconnected during this time, the PCM may be damaged. To cancel this mode, disconnect the negative cable from the 12 volt battery or jump the SCS line with the HDS after the ignition switch is turned to ACC (I) or to LOCK (0).
