- [SA\-041\-26a](/bulletins/11037899.md), 2026-10-03, Service bulletin: ELECTRICAL SYSTEM. DESCRIPTION If you encounter any type of electrical concern \(e.g, dead battery, engine no start, DTC\(s\) stored...\), interview the customer before proceeding with normal MGSS diagnosis by asking if any aftermarket devices have been installed. Aftermarket devices may be the cause of the electrical concern. Below are a few examples of unusual electrical concerns caused by aftermarket devices. Examples: 1. Devices connected to the DLC\-2 \(battery discharge/DTC stored\) 2. Devices plugged into the 12V outlet 3. GPS tracking device \(engine no start/battery discharge\) 4. Dash cam \(DTC stored\) 5. Non\-certified USB cable \(Apple Carplay™/ Android Auto™ will not connect\) 6. Over\-sized wheels/tires \(incorrect GPS location\) 7. DTC C0023:14 8. Decorative trim and/or cover on the START/STOP ENGINE button
- [SA\-041\-26](/bulletins/11034447.md), 2026-07-03, Service bulletin: ELECTRICAL SYSTEM; ENGINE. This SA supersedes the previously issued SA\(s\) listed below. The changes are noted in Red. SA\-061/25 12/17/25 DESCRIPTION If you encounter any type of electrical concern \(e.g, dead battery, engine no start, DTC\(s\) stored...\), interview the customer before proceeding with normal MGSS diagnosis by asking if any aftermarket devices have been installed.

Decorative trim and/or cover on the START/STOP ENGINE button Example 1: Some electrical devices connected to the DLC\-2 connector by insurance or mobile phone companies may cause: Battery discharge. The device may disrupt the CAN system battery saver mode. • IDS/MMDS will not communicate with the vehicle due to poor DLC\-2 connection. The aftermarket device may cause DLC\-2 female terminals to spread open.
- [SA\-021\-26](/bulletins/11032100.md), 2026-05-05, Service bulletin: ELECTRICAL SYSTEM; STRUCTURE:BODY. This Service Alert supersedes the previously issued SAs and bulletin\(s\) listed below: The changes are noted below in red. SA\-010/23 02/09/23 DESCRIPTION Some customers may experience one or more electrical malfunctions after a vehicle body repair. A newly painted fender stay \(2\) may be causing a poor front harness \(1\) ground connection. The front fender stay \(2\) newly painted surface at ground point \(3\), where attachment bolt \(4\) is seated, may create a poor front harness ground connection. NOTE: DO NOT paint ground point \(3\) attachment bolt \(4\) is seated. NEWLY INSTALLED FRONT FENDER STAY NOTE: CAUTION: If the bolt \(4\) contact area \(3\) is painted when the front fender stay \(2\) is newly replaced, it could cause a malfunction in the PCM. Before painting a newly replaced part, protect the bolt \(4\) contact area \(3\) with masking tape \(5\) as shown in the figure.
- [09\-005\-26](/bulletins/11028099.md), 2026-02-03, Service bulletin: LANE DEPARTURE: BLIND SPOT DETECTION; ELECTRICAL SYSTEM. If the right\-side Blind Spot Monitoring \(BSM\) control module is replaced for any reason, it is also necessary to replace the left\-side BSM control module in order to complete the radar aiming procedure. If the right\-side BSM control module is replaced alone, "Automatic Configuration" and "BSM Radar Aiming" cannot be completed due to a programming error in the module. In most cases, if the left\-side BSM control module is replaced alone, "Automatic Configuration" and "BSM Radar Aiming" can be completed without any problem \(See CAUTION below for more details\). Other possible symptoms that may be found if the right\-side BSM module is replaced alone: BSM aiming fails “BSM OFF" indicator ON Center Display warning message BSM failsafe \(No operation\) DTC U3000:54 stored in memory DTC U1A4B:54 stored in memory \(CX\-3, MX\-5 only\) NOTE: Since a new BSM control module does not retain the vehicle specification information, it is necessary to acquire and store the vehicle specification information transmitted via CAN communication from the combination meter through automatic configuration after replacement.

Use the following test procedures in this Service Bulletin to test Mazda vehicle batteries and to generate a Warranty Code. NOTE: A Warranty Code is required for warranty claim submission Battery Identification \(Mazda batteries have 2 rating types\) 1. JIS \(Japanese Industrial Standard\): JIS codes are six\-digit alpha\-numeric markings molded into the top of the battery to identify a battery by the capacity \(amps\), dimensions, and battery terminal type. Vehicles manufactured in Japan come from the factory with a JIS rated battery. NOTE: Replacement batteries may use a CCA rating. If so, use the CCA rating listed on the battery. 2. CCA \(Cold Cranking Amps\): CCA ratings are normally located on a sticker affixed to the top of the battery to indicate a battery’s Cold Cranking Amps. CCA rated batteries are supplied with domestically produced vehicles. NOTE: If an incorrect CCA rating is entered into the Mazda DCA\-8000, it will result
