CX-60 (KH) - Mode Two Charging Interruptions Occurred Prematurely

[JamesStv]

CX-60 (KH) - Mode Two charging interruptions occurred inadvertently prior to completion.

TSB NUMBER: R018/25 (Europe and United Kingdom)
Initial Publication Date: April 15, 2025


NOTICE: Relevant Model: CX-60 (KH) equipped with e-SKYACTIV PHEV (Plug-in Hybrid Electric Vehicle).

DESCRIPTION: Certain customers may see unintended cessation of MODE 2 charging prior to completion while utilising a MENNEKES-manufactured Charge Cable.

CAUSE: An instantaneous power interruption during the temperature calibration of the power sensor in MENNEKES-manufactured charging cables is perceived by the vehicle as an anomaly, resulting in the cessation of charging.

MODIFICATION IN MASS PRODUCTION: The control software of the On-Board Charger (OBC) has been revised.

SUBJECT: VIN AND PRODUCTION DATE RANGE: Europe (Left-Hand Drive and United Kingdom Specifications) JMZ KH B * 250001 to 999999 - To Be Determined.

REPAIR PROCEDURE: 1. Reprogram the On Board Charger (OBC) utilising the Mazda Modular Diagnostic System (M-MDS) with the Mazda Diagnostic And Repair Software (MDARS).

If the current Calibration file name displayed on the ECU FILENAME screen matches that in the Calibration Files Information or has a later alpha suffix, reprogramming is unnecessary, as the file has already been updated; seek additional guidance.

NOTE: Consult the Service Information E010/24* "ECU REPROGRAMMING PROCEDURE USING MDARS".

2. Erase Diagnostic Trouble Codes (DTC).

3. Confirm the repair by activating the power (READY On) and ensuring that there is no activation of the MIL or any abnormal warning lights.

It is reasonable to assert that Australian, New Zealand, and South African CX-60 models produced around the same date would possess the same or a comparable Service Bulletin.
If the dealer verifies the OBC with MDARS and observes the identical OLD File Version now in CX-60, updating the OBC to the NEW 'E' File KBB3-30WF2-E will resolve the issue.

Impressive. Despite Mazda's repeated assertions that the problem lies with the faulty charging cable they provided with the vehicle, it has become evident that the issue originates from the car itself, rather than the connection.
I must admit, I perceive a potential red herring in this situation, as no other cables, aside from the blue Mennekes ones, cause the vehicle to cease charging unexpectedly.

[Mezuzzi]

I experienced this issue as well. The charging brick was replaced under warranty, resolving the issue.

[Istairde]

I was quite frustrated because my car frequently ceased charging, almost 90% of the time. Ultimately, the dealer opted to provide me with a new charging cable (13A instead of 10A, by the way), and it has consistently charged without interruption since then. Completely dependable at present.

This pertains to the Charge Cable manufactured by MENNEKES; however, I do not have the same issue when charging the vehicle with the Ohme wallbox.

[Angurita]

I visited today to have this examined; the dealer performed the software upgrade. We shall observe the outcome.
