Inadvertent Exterior Lamp Control
The PZM automatically turns off the exterior lamps after ten minutes if the headlamp switch has been accidentally left on after the ignition has been turned to the "LOCK" or "ACC" position. Exterior lamps are restored under the following conditions:^ The PZM wakes up from a power down.
^ The ignition switch is turned to the "RUN" or "START" position.
^ The PZM receives a serial data message from the IPC that the parklamp switch has been cycled.
^ The PZM enables exterior lamp power for RFA or theft deterrent flash.
