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.
Cruise Mode
2016 Dodge and Ram Charger R/TSECTION Cruise Mode
When the engine is at operating temperature, this is a Closed Loop mode. At cruising speed, the PCM receives inputs from:
- Air conditioning select signal (if equipped)
- Air conditioning request signal (if equipped)
- Battery voltage
- Camshaft Position Sensor (CPS) signal
- Engine Coolant Temperature (ECT) sensor
- Intake Manifold Air Temperature (MAT) sensor
- Manifold absolute pressure (MAP) sensor
- Accelerator Pedal Position Sensor (APPS)
- Throttle position sensors (TPS)
- Crankshaft Position (CKP) sensor
- Battery voltage
- Park/neutral switch (gear indicator signal)
- Oxygen (O2) sensors
Based on these inputs, the following occurs:
- Voltage is applied to the fuel injectors with the ASD relay via the PCM. The PCM will then adjust the injector pulse width by turning the ground circuit to each individual injector on and off.
- The PCM monitors the O2S sensor input and adjusts air-fuel ratio.
- The PCM adjusts ignition timing by turning the ground path to the coils on and off.
- The PCM operates the A/C compressor clutch through the clutch relay. This happens if A/C has been selected by the vehicle operator and requested by the A/C thermostat.

- • 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.
