DTC P061F: Internal Control Module Throttle Actuator Controller Performance Problem
 
 
 
 
TECHNICAL DESCRIPTION
  • To judge whether fail-safe control can be performed, check that power supply to the throttle actuator control motor circuit can be stopped by turning the throttle actuator control motor relay to OFF position momentarily.
 
 
DTC SET CONDITIONS
Check Condition
  • Ignition switch is "ON" position.
Judgment Criterion
  • Power supply to the throttle actuator control motor cannot be shut down (though power supply is stopped).
 
 
FAIL-SAFE AND BACKUP FUNCTION
  • Microcomputer is reset.
 
 
TROUBLESHOOTING HINTS (The most likely causes for this code to be stored are: )
  • Throttle actuator control motor relay circuit failed.
  • ECM failed.
 
 
 
DIAGNOSIS
Required Special Tools:
  • MB992744: Vehicle communication interface-Lite (V.C.I.-Lite)
  • MB992745: V.C.I.-Lite main harness A
  • MB992747: V.C.I.-Lite USB cable short
  • MB992748: V.C.I.-Lite USB cable long
  • MB991958: Scan Tool (M.U.T.-III Sub Assembly)
    • MB991824: Vehicles Communication Interface (V.C.I.)
    • MB991827: M.U.T.-III USB Cable
    • MB991910: M.U.T.-III Main Harness A (Vehicles with CAN communication system)
STEP 1. Using scan tool (M.U.T.-III), read the diagnostic trouble code (DTC).
cautionTo prevent damage to scan tool (M.U.T.-III), always turn the ignition switch to the "LOCK" (OFF) position before connecting or disconnecting scan tool (M.U.T.-III).
(1) Connect scan tool (M.U.T-III) to the data link connector.
(2) Turn the ignition switch to the "ON" position.
(3) Read the DTC.
(4) Turn the ignition switch to the "LOCK" (OFF) position.
Is DTC P0657 stored?
Refer to, DTC P0657 - Throttle Actuator Control Motor Relay Circuit Malfunction .
Go to Step 2.
 
STEP 2. Using scan tool (M.U.T.-III), read the diagnostic trouble code (DTC).
(1) Turn the ignition switch to the "ON" position.
(2) After the DTC has been deleted, read the DTC again.
(3) Turn the ignition switch to the "LOCK" (OFF) position.
Is DTC P061F stored?
Replace the ECM (Refer to, Removal and Installation ).
It can be assumed that this malfunction is intermittent. Refer to GROUP 00, How to Use Troubleshooting/Inspection Service Points - How to Cope with Intermittent Malfunctions .
