A/T P Indicator Circuit

DESCRIPTION

The propeller shaft and wheels are free even when the transmission shift lever is set to P as long as the transfer shift lever is in the neutral position. The A/T P indicator light lights up to warn the driver that the propeller shaft and wheels are not locked.
If the A/T P indicator light comes on, the transfer shift lever should be shifted out of the neutral position.
