Power supply, delayed X-supply, value
Measurement range: 0 - 18 V
Normal value when the generator (GEN) is charging: 13.0 - 14.5 V
The value indicates the voltage at the climate control module (CCM). Delayed X-supply means that the power supply is maintained for 1 minute after the ignition is switched off. This is so that functions such as blower fan run-on and damper motor self-adjustment can be activated.
