| Part |
Purpose |
|---|---|
|
Service plug
|
Interrupts short-circuit current to prevent a short to the 24.3 V related electricity stored in the capacitor (Mazda M Hybrid) during servicing and the flow of large amounts of current.
|
|
Temperature sensor
|
Detects the capacitor (Mazda M Hybrid) temperature for the purpose of assuring capacitor (Mazda M Hybrid) performance because capacitor (Mazda M Hybrid) performance deterioration is caused by a continuous capacitor (Mazda M Hybrid) high temperature.
|
|
Capacitor (Mazda M Hybrid) relay
|
Switches the electric circuit when the ignition is switched off, when in pre-charge mode for Mazda M Hybrid operation, if the vehicle is in a collision, and when it is in fail-safe.
|
|
Plug (for compulsory discharge)
|
Equipped to the resistor on the capacitor (Mazda M Hybrid) so that it can be disposed of after discharging the capacitor (Mazda M Hybrid) for the purpose of assuring safety. The capacitor (Mazda M Hybrid) can be transported safety by the compulsory discharge of the capacitor (Mazda M Hybrid) using the resistor.
|
|
LED
|
Turns on the LED during compulsory capacitor (Mazda M Hybrid) discharging.

Capacitor (Mazda M Hybrid) relay operation
| When capacitor (Mazda M Hybrid) relay is disconnected |
Outline |
|---|---|
|
Ignition is switched off
|
• To prevent a short to the 24.3 V related power or to reduce back-up current during servicing, the capacitor (Mazda M Hybrid) relay is disconnected approx. 30 s after the ignition is switched OFF.
|
|
During collision
|
• The capacitor (Mazda M Hybrid) relay is disconnected to assure safety in a vehicle collision.
|
|
In pre-charge mode for Mazda M Hybrid operation
|
• The capacitor (Mazda M Hybrid) relay is disconnected to assure excitation current to the generator when power from the battery is used (in pre-charge mode for Mazda M Hybrid operation).
|
|
In fail-safe
|
• The capacitor (Mazda M Hybrid) relay is disconnected while in fail-safe.
