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.
Scan Tool Data Definitions
Battery Voltage: The scan tool displays 0-30 volts. Display indicates the voltage measured between the module's battery positive voltage circuit and ground circuit.
Ignition 1: The scan tool displays Active/Inactive. The scan tool displays Active when the Ignition 1 input circuit of the RIM receives a battery voltage signal from the IGN-1 RELAY.
Ignition 1 Run/Crank: The scan tool displays Active/Inactive. The scan tool displays Active when the Run/Crank circuit of the DIM receives a battery voltage signal from the ignition switch.
Ign. Accessory/Run: The scan tool displays Active/Inactive. The scan tool displays Active when only the Accessory/Run circuits of the DIM receives a battery voltage signal from the ignition switch.
Ignition Switch: The scan tool displays Accy/Crank/Off/RAP/RAP-Unlock/Run/Unlock. The scan tool displays Accy when the accessory circuit of the DIM receives a battery voltage signal from the ignition switch. The scan tool displays Crank when the Crank/Run circuit of the DIM receives a battery voltage signal from the ignition switch. The scan tool displays Off when none of the power moding circuits of the DIM receive a battery voltage signal from the ignition switch. The scan tool displays RAP, when RAP is active and none of the power moding circuits of the DIM receive a battery voltage signal from the ignition switch. The scan tool displays Run when all of the power moding circuits of the DIM receive a battery voltage signal from the ignition switch.

When to See a Mechanic
Stop DIY work and contact a certified mechanic immediately if any of the following apply:
- • You smell fuel, burning insulation, or see smoke.
- • Brakes feel soft, pull hard to one side, or make grinding noises.
- • The engine overheats, stalls repeatedly, or misfires under load.
- • You are missing required tools, torque specs, or safe lifting equipment.
- • You are not confident in the next step or safety outcome.
