This code indicates that the voltage for the Diesel Particulate Filter (DPF) regeneration inhibit switch is above normal, suggesting that the switch is stuck on or there is a short to power. This could be due to a faulty switch, wiring issues, or problems within the control module.

READ MORE

This code indicates that the Hybrid Exhaust Actuator is not able to reach the intended position, suggesting that the Engine Exhaust Pressure Regulator Vent Valve position is either not responding or out of adjustment. This can be caused by mechanical issues, sensor problems, or faults in the actuator control system.

This code indicates that the voltage for the keypad is above normal, suggesting that the display mode switch is stuck on or the switch used to navigate user menus is defective. This could be due to a short circuit, a faulty switch, or issues within the control module.

READ MORE

This code indicates that the current for the engine fuel shutoff 2 control is above normal or the pull-in coil output circuit is shorted to ground. This could be due to a short circuit in the wiring, a defective pull-in coil, or problems with the control module.
