PARK POSITION SWITCH

Description

INFOID:0000000007356171

Park position switch is installed on A/T shift selector. It is turned OFF when the A/T selector lever is in P posi-

tion. The driver seat control unit judges that the A/T selector lever is in P position if continuity does not exist in

this circuit.
