Battery 1

Displays 0.0-25.5 V. This parameter is the system voltage measured by the BCM at the BCM battery input.

Shifter Inhibit

Displays Low TFT/Normal. On vehicles with the CVT transmission, this parameter indicates the ECM operational status of the transmission. Low TFT indicates the transmission fluid temperature is too low to allow the shift lever out of the PARK position. Normal indicates transmission fluid temperature is warm enough to allow normal shift lever operation.
