Monitor Description
WARNING: This page is about a different car, the 2007 Toyota Land Cruiser. However, it is still accessible from the selected car via links, so may be relevant.
The ECM monitors the transfer L4 position switch to determine when the transfer-case L4 gear is engaged. If the transfer-case L4 gears remain engaged under all of the following conditions, the ECM will conclude that there is a malfunction of the transfer L4 position switch:
- The transfer L4 position switch indicates that the L4 transfer-case gears are engaged.
- Transfer-case shift lever is in the "H" position.
- Transfer-case output shaft rpm is between 750 and 3,000 rpm.
- The specified time period has elapsed.
Then the ECM will illuminate the MIL and store the DTC.
