Some customers may complain the A/C blows warm. This may be caused by one of two things. Cause 1: After accelerating in hot weather, the A/C blows warm air for a longer time than other models. This is caused by improper control software of the PCM not allowing the A/C compressor to resume properly after acceleration. During a hard acceleration above a certain throttle level opening, the PCM stops the A/C compressor operation for better acceleration. It then resumes the compressor operation after the acceleration. To eliminate this concern, the control software of the PCM has been modified. Cause 2: Insufficient cooling performance at ambient temperature of around 68 ðF (20 ðC) in daytime. This is caused when both the ambient temperature and the cabin temperature are at around 20 ðC (68 ðF), auto A/C set at around 20 ðC (68 ðF) may not cool down the cabin temperature properly. To eliminate this concern, control software of the dash-electrical supply unit (Dash-ESU) has been modified.

Some customers may experience a no start because the battery is discharged after the vehicle is parked for more than 8 hours. This may be caused by one or more of the following, resulting in excessive parasitic draw (dark current) on the battery. 1. The vehicle control system may not have gone to sleep because a key fob was left in the vehicle after the ignition switch was turned off and the doors were closed. This is caused by improper BCM control logic which allows a higher parasitic draw (approx. 6A) to continue for approximately 6 minutes until the vehicle control system goes into sleep mode. If the doors are operated frequently for car washing or luggage loading/unloading etc., it prevents the vehicle control system from sleeping during that time. 2. The parking lights may have been left on because the warning sound for lights on is a short ding, and it may not be noticed. 3. [With Full-Auto A/C] The climate control unit may not have gone to sleep because the hazard warning switch was pressed after the ignition was turned off. This is caused by improper control logic of the climate control unit. To correct these concerns: 1. The control software of the body control module (BCM) has been modified to shorten the time until going into the sleep mode to approximately 2 minutes. 2. The control software of the body control module (BCM) has been modified to change the lights on warning sound to a continuous one. 3.

Some vehicles without i-ACTIVSENSE may exhibit that the i-ACTIVSENSE OFF symbol turns on in the instrument cluster after replacing the speedometer. Since vehicles without i-ACTIVSENSE do not have an i-ACTIVSENSE switch, there is no way to clear the i-ACTIVSENSE OFF symbol. This is caused by a communication error between the new speedometer and the vehicle control module (VCM) due to a software level difference.

Some vehicles may exhibit an excessive body vibration when idling or driving after being left in extremely cold weather (-20ðC/-4ðF or below) for a long time. This is caused by the No.1, No. 3 and No. 4 rubber hardening due to material characteristics. NOTE: This concern only happens in extremely cold weather, therefore this TSB is only applicable for extremely cold regions. To eliminate this concern, the cold environment performance of the engine mount rubber has been increased by changing the rubber material.

Some vehicles may exhibit water leaking into the passenger compartment from the rear door through the bottom of the service hole behind the rear door trim during rain or when washing the vehicle. This is caused by one of the following: *Since the material of the seal rubber is not resistant to surfactants, the rubber deteriorates when the vehicle is washed and allows water to penetrate into the seal rubber of the service hole cover. *The lower tabs of the service hole cover may not have been completely engaged at the factory. To eliminate this concern, the seal material of the service-hole cover has been changed (Japan built Mazda3) and a mass production change will be implemented in the future (Mexico built Mazda3 and CX-30).

The new AWD rear differential DOES NOT come with a breather cap on the rear of the differential, therefore a new one will need to be ordered and installed when replacing the differential. NOTE: The breather threads have a sealant and locking compound that prevents it from being reused. Refer to GEPC for the correct part number of the Differential Breather. The instructions on MGSS will be updated soon to include replacing the breather when replacing the differential with a new unit.
