In connection with the above SSP, we will also release a Mazda Service Program (MSP) under the name AM036A which will improve the fast charge (DC - charge) in cold conditions and improve the car's ability to maintain the interior heat at extremely cold temperatures . On some MX-30 vehicles, it may take a long time to complete the fast charge in cold conditions. We solve this by reprogramming the software in PCM and B ECM. After the software update, you can change the mode of how the high-voltage battery's heater works, there will be a normal mode and a mode for colder temperatures. The situation for colder temperatures will improve the fast charging time, but the car's range will be affected as the high-voltage battery's heating system will have to work harder. More information on how to change mode can be found on the next page
Procedure for switching between "Normal Mode" and "Cold Mode" Please consider explaining these important points to customers. By activating the battery heater from between 5-10 ° C, the time for fast charging is shortened by about 55 minutes from SOC (charging state) 20% to 80% at -10 ° C. This function is only useful for customers who often uses DC charging (fast charging) as it does not significantly affect the time for AC charging. Follow the procedure below if the customer prefers to change the performance to improve the fast charging time when the ambient temperature is low. "Normal mode" when the ambient temperature warms up: 1. Switch ON the READY OFF mode 2. Move the gear selector to the P position. 3. Hold down the pedals and perform the following steps within 10 seconds (the pedals should be depressed throughout the process). a) Press the minus button on the steering paddle A (-) three times. b) Press the plus button on the steering wheel paddle B (+ / OFF) three times. c) Press the minus button on the steering paddle A (-) three times. d) Press the plus button on the steering wheel paddle B (+ / OFF) three times.
Supplementary information: "EV system warning light" flashes as the conditions below when the changeover has been carried out correctly. When switching to "Cold mode" correctly: Flashes the lamp 4 times When switching to "Normal mode" correctly: Flashes the lamp twice 4. Release the brake pedal and accelerator pedal. Switch OFF the ignition mode. 5. Check for any error codes / DTCs and delete if necessary. Reference information: This switching procedure is applicable in both cases when switching from "Cold Mode" to "Normal Mode" and when switching from "Normal Mode" to "Cold Mode".
AM035A should give better 'treatment' for the 12v battery (avoid empty 12v battery) and improvement (bugfix) for cabin heating
