TRANSMISSION/TRANSAXLE FEATURES
MTX [G35M-R]
Improved operability

  1. Linked, triple-cone synchronizer mechanism adopted for 1GR and 2GR
  2. Linked, double-cone synchronizer mechanism adopted for 3GR and 4GR
  3. Double-ball construction detent balls adopted (small balls positioned on the backside of the balls inserted in the rod end)
  4. Optimal control rod end load characteristics
  5. Special surface finish (bushings with teflon coating for low friction resistance adopted) used on shafts of linkage parts (shift rod, crank lever, control rod)
  6. Optimal positioning of reverse link support/leverage points

ON-BOARD DIAGNOSTIC (OBD) SYSTEM OUTLINE [FN4A-EL]
The OBD system has the following functions: 

  1. Malfunction detection function: detects malfunctions of the input/output devices and system components of the ATX.
  2. Fail-safe function: fixes the output device function and input value of the sensors/switches to ensure minimum vehicle drivability when a malfunction is detected.
  3. Memory function: stores the DTC when a malfunction is detected.
  4. PID data monitoring function: monitors the input/output signal and calculated value of the PCM and sends the monitoring data to the WDS or equivalent.
  5. Simulation function: Allows override operation of simulation items for input/output system parts preset in the PCM.

Malfunction Detection Function

  1. In the malfunction detection function, the PCM detects malfunctions in the automatic transmission while driving.
  2. When vehicle driving conditions correspond with a preset malfunction detection condition, the PCM determines that the automatic transmission has a malfunction and stores the corresponding DTC.
  3. When a malfunction is detected, stored DTCs can be retrieved using the WDS or equivalent connected to the DLC-2.

MEMORY FUNCTION [FN4A-EL]

  1. The memory function stores malfunction information detected in the malfunction detection function. Once malfunction information is stored, the memory will not be cleared even when the ignition switch is turned off (LOCK position) or the malfunction is repaired.
  2. The stored memory (malfunction information) can be cleared using the WDS or equivalent, or by disconnecting the negative battery cable.

MALFUNCTION INDICATION FUNCTION [FN4A-EL]
The malfunction indication function illuminates the MIL or AT warning light when the malfunction detection function when it determines there is a malfunction.
FAIL-SAFE FUNCTION [FN4A-EL]
In the fail-safe function, minimum vehicle drivability is obtained by changing the signals that are determined to be malfunctions by the malfunction detection function to the preset values, and limiting PCM control.

PARAMETER IDENTIFICATION (PID) DATA MONITORING FUNCTION [FN4A-EL]
The PID mode allows access to certain data values, analog and digital input and output, calculations and system state information.
