PGM-FI SYSTEM DESCRIPTION - ELECTRONIC CONTROL

The powertrain control module (PCM) consists of a CPU memory (storage unit) and Input/Output that control the fuel injection, injection timing, idling 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 version of the program using the MVCI.

MIL Bulb Check and Readiness Code Condition

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 bulb condition. USA and Canada models: If any readiness codes are not set to complete, the MIL flashes five times. If all readiness codes are set to complete, the MIL goes off.

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 this mode, disconnect the negative cable from the 12 volt battery or jump the SCS line with the HDS after the vehicle is turned to the OFF (LOCK) mode.

Engine Compartment PCM

For serviceability and weight reduction, the wire harness has been shortened. The PCM is now positioned in the engine compartment. To ensure PCM operation in the engine compartment, the PCM main body and the connectors are water-proof. When diagnostic/troubleshooting is done at the PCM connector, use the terminal test port above the terminal you need to check, not the wire side.

PGM-FI SYSTEM DESCRIPTION - 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.
