Update to include Porsche Mobile Charger Connect
Replacement cable minimum requirement

Condition
The Porsche Mobile Charger Plus (PMC+) and Porsche Mobile Charger Connect (PMCC) can fail to read a new
temperature-sensing NEMA supply cable after updating to PMC+ SW level 3000 or PMCC SW 4501.
This condition can occur on all NEMA variants of temperature sensing 250V cables and displays in two phases
immediately after plugging into the power outlet. Note that this will occur before the charger is connected to
a vehicle.
Phase 1: (~20 seconds)
The uppermost Charge Status LED illuminates solid white, while the top “House” LED will illuminate solid yellow for a
few seconds as shown in figure 1.
Phase 2: (indefinite)
The uppermost Charge Status LED illuminates solid red, and the bottom “Charger” icon LED flashes yellow as shown
in figure 2 as long the unit remains plugged into an outlet.

Technical Background
A helpful reference table of fault patterns is listed in the Malfunctions section of the Porsche Mobile Charger Plus
Operating Instructions. The aforementioned fault pattern is described in the screenshot below.

Figure 4
When connecting a Porsche Mobile Charger to the PIWIS tester for diagnostics, one of the temperature sensors
in the Actual Values menu is always shown implausible at 200 ⁰C as in Figure 5, regardless of which infrastructure
cable is connected. This should NOT be used to diagnose a faulty infrastructure cable without the condition
previously described in this case.

Figure 5
The inability to read the infrastructure cable is currently understood to be an internal defect due to the sensitivity
of the PMC+/PMCC software with some NEMA cables. Association between a functioning and non-functioning
cable is currently random with regard to Porsche Mobile Charger.

Service Information
While the Operating Instructions recommend removing and reinserting the power plug, this does not always remedy
the condition. There is currently no known correlation of this condition to supply cable production date. If a charger
exhibits the described behavior with a particular supply cable, normal operation cannot be guaranteed with a power
supply cable of later production date. Each cable must be physically tested with the customer’s charger at the
Porsche Center to confirm functionality before returning the updated charger and new supply cable to the customer.
This condition is not directly a fault of the temperature-sensing supply cable. New cables that do not work on the
affected PMC+/PMCC devices demonstrating this condition can work normally on PMC Basic part number variants
with updated software. If the customer PMC+/PMCC continues to display this behavior with at least 5 replacement
supply cables after multiple outlet plug-in cycles, it should be replaced.
Please upload a screenshot of the Porsche Mobile Charger software version in the Extended Identifications menu
of the PIWIS Tester to the PCSS job entry when claiming replacement parts for these situations. In cases with
PMCC, please also provide a picture of the software update screen in the settings where the current Commboard
software version is displayed.
Documentation and reference information in other systems must be reviewed and understood before diagnosing
customer concerns.
