Test W: 4X4 Low Indicator Is Never/Always On

Pinpoint Test W: The 4X4 LOW Indicator Is Never/Always On





Normal Operation
The four-wheel drive (4WD) control module sends the 4x4 low command, over the high speed controller area network (HS-CAN). The instrument cluster monitors the command from the 4WD control module and illuminates the 4x4 LOW indicator when the vehicle is in 4x4 low.

Possible Causes
- 4WD control module
- instrument cluster
