Brake override system operation inspection

1. Start the engine and let it idle.
2. Verify that the engine speed becomes less than 1, 200 RPM under the following conditions.
   • N position
   • Engine speed of 3, 000 RPM or more with accelerator pedal depressed
   • Brake pedal depressed
     • If the engine speed becomes approx. 1, 200 RPM, clear the PCM DTC using the M-MDS. (Brake override system operation is normal).
     • If the engine speed does not become approx. 1, 200 RPM, inspect for the following parts, then repair or replace the malfunctioning part:
   • APP sensor (See ACCELERATOR PEDAL POSITION (APP) SENSOR INSPECTION ).
   • Brake switch No. 1 (See BRAKE SWITCH INSPECTION ).
   • Brake switch No. 2 (See BRAKE SWITCH INSPECTION ).
   • Communication between PCM and TCM (See FOREWORD ).

Wastegate Valve Operation Inspection

1. Connect the M-MDS to the DLC-2.
2. Perform the KOEO or KOER self test. (See KOEO/KOER SELF TEST [PCM (VIN Y)] ).
3. Verify that DTC P0045:00 or P0046:00 is not displayed. (See ON-BOARD DIAGNOSTIC TEST [PCM (VIN Y)] ).
   • If DTC P0045:00 or P0046:00 is displayed, perform the DTC inspection. (See DTC P0045:00 [PCM (VIN Y)] .) (See DTC P0046:00 [PCM (VIN Y)] ).
4. Access the following PCM PIDs using the M-MDS. (See ON-BOARD DIAGNOSTIC TEST [PCM (VIN Y)] ).
   • WGV_ACT
   • WGV_DSD
5. Accelerate and decelerate the vehicle, and drive at normal speed, and verify that the data monitor item WGV_ACT value changes in conjunction with the WGV_DSD value.
   CAUTION:

   • 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.
   • While performing this step, always operate the vehicle in a safe and lawful manner.
   • If this change cannot be verified, replace the dynamic pressure turbo. (See DYNAMIC PRESSURE TURBO REMOVAL/INSTALLATION ).
