  2. *2: except Multi-mode Automatic Transmission

MONITOR DESCRIPTION

For security, the park/neutral position switch detects the gearshift position so that engine can be started only when the vehicle is in the P or N shift position.
When the park/neutral position switch and shift lock control unit assembly (transmission control switch) send more than one signal at a time from switch positions P, R, N, D, M*1, S*2 or B*2, the ECM interprets this as a fault in the switch. The ECM will turn on the MIL and store the DTC.

  2. *2: except Multi-mode Automatic Transmission
