Electronic Control 

The powertrain control module (PCM) consists of a CPU memory (storage unit) and inputs/outputs that control the fuel injection, injection timing, and electronic throttle control system (ETCS).

Fail-Safe Function 

When a malfunction occurs in the signal from a sensor or from another control unit, the PCM ignores that signal and substitutes a pre-programmed value that allows the engine to continue running. This causes a Confirmed DTC to be stored and the MIL to come on.

Updated Function 

The PCM has a rewritable ROM. The ROM can acquire the latest software version.

MIL Indicator Check 

When the vehicle is turned to the ON mode, the PCM turns on the MIL via the F-CAN circuit for about 15 to 20 seconds to check the indicator condition.

Self Shut Down (SSD) Mode 

After the vehicle is turned to the OFF (LOCK) mode, 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 the SSD, jump the SCS line with the HDS after the vehicle is turned to the OFF (LOCK) mode.

Two Drive Cycle Detection Method 

The DTCs are detected with one or two driving cycle method in the PCM. Specific DTCs which are considered as a not intermittent failure apply the two driving cycle method.When a malfunction occurs in the signal from a sensor or from another control unit in the first drive cycle, the PCM stores a pending DTC. The MIL does not come on at this time. If the failure continues in the second drive cycle, the PCM stores a confirmed DTC and turns on the MIL.

Engine Start Conditions 

(refer to the electric brake booster system boost restriction)

When any of the following conditions are met, the engine will start.

Injection Control 

Fuel injection controls include fuel injection amount control, fuel cut control, and fuel pump control. Adaptive PGM-FI (programmed-fuel injection) technology enables accurate fuel controls, which contributes to increasing engine power and decreasing fuel consumption.

Fuel Injection 

The fuel injection is determined by adding correction values to a basic injection. The powertrain control module (PCM) controls the amount of fuel injection by the length of time the injector is energized.

Fuel Injection Timing 

The fuel injection timing is determined by the PCM, which calculates the injection time for each cylinder based on the signals from the crankshaft position (CKP) sensor and camshaft position (CMP) sensor A. The PCM then controls the time to energize the injector. Therefore, the fuel injection control will vary depending on the state of the vehicle.

Ignition Timing Control 

The powertrain control module (PCM) contains the memory for basic ignition timing at various engine speeds and manifold absolute pressures. It also adjusts the timing according to engine coolant temperature and intake air temperature.

Fuel Cut-off Control 

Fuel Cut-off Control 

After warming up, during deceleration with the throttle valve slightly open from the fully closed position, the powertrain control module (PCM) stops the fuel injection when the engine speed is over the specified value to improve fuel efficiency.

Fuel cut-off at high engine speed 

To prevent engine damage, the PCM stops the fuel injection when the engine speed is in the limited area (red zone). PCM stops fuel injection while the vehicle is driven and while at a stop. Engine speed fuel cut is lower when stopped compared to when driven.

At High Speed Driving 

PCM stops fuel injection when the vehicle speed is over than the listed speed in the following chart.
