/*
 * Nissan X-Trail T31 CAN map — lock, doors, ignition, mirrors.
 *
 * Platform: T31 (2007–2014). Same CAN COMM as Qashqai J10.
 * Bus: 500 kbit/s, 11-bit IDs.
 *
 * Tap:
 *   OBD-II pin 6 CAN-H, pin 14 CAN-L
 *   or BCM (behind glovebox), green 40-pin: pin 20 CAN-H blue, pin 40 CAN-L pink
 * Do not fit extra 120 ohm — the bus is already terminated.
 *
 * T31 has electric folding mirrors on some trims, but BCM does not publish
 * a cyclic "fold mirrors" frame. The door switch reverses motor polarity.
