Fuel Cut Control System Inspection

Warm-up engine and idle it.
Turn off the electrical loads and A/C switch.
Connect the M-MDS to the DLC-2.
Access the RPM and FUELPW PIDs. (See ON-BOARD DIAGNOSTIC TEST [MZR 1.5] ).
CAUTION:
- While performing this step, always operate the vehicle in a safe and lawful manner.
- When the M-MDS is used to observe monitor system status while driving, be sure to have another technician with you, or record the data in the M-MDS using the PID/DATA MONITOR AND RECORD capturing function and inspect later.
Monitor both PIDs while performing the following steps:
1. Drive the vehicle with the engine speed is 4,000 rpm .
2. Release the accelerator pedal (brake pedal is not depressed) and verify that the fuel injector duration time is 0 ms , and 2-5 ms when the engine speed drops 1,200 rpm or less .
  - If not as specified, inspect the following:
    - ECT sensor No.1 and related wiring harness (See ENGINE COOLANT TEMPERATURE (ECT) SENSOR INSPECTION ).
    - CPP switch, Neutral switch and related wiring harness (MTX) (See CLUTCH PEDAL POSITION (CPP) SWITCH INSPECTION ). (See NEUTRAL SWITCH INSPECTION ).
    - TR switch and related wiring harness (ATX) (See TRANSAXLE RANGE (TR) SWITCH INSPECTION ).
