GROUP CHA MODEL Multiple Models NUMBER DATE 074 (Rev 1, 9/13/2016) August 2016 TECHNICAL SERVICE BULLETIN MDPS FLEXIBLE COUPLING REPLACEMENT SUBJECT: NOTICE This bulletin has been revised to include additional information. New/revised sections of this bulletin are indicated by a black bar in the margin area. This bulletin is issued to provide information about the replacement of the flexible coupling in the MDPS motor of some vehicles which might experience a “knock” noise originating from the MDPS, when moving the steering wheel to right or left when the vehicle is stopped. This is caused by premature wear of the flexible coupling in the MDPS motor. If any “knock” noise from the MDPS occurs, replace the affected flexible coupling only with an improved one, following the Replacement Procedure below. Please note that Replacement Procedures 1, 2 and 3, as shown below, vary depending on the model. Calibration Procedures only apply to Replacement Procedures 1 and 3. For reference, there are 2 types of torque sensors to detect revolution and torque in the MDPS system. One is the optical type which detects when light is transmitted and the other is the magnetic type which detects changes in polarity.
