Test V: 4X4 High Indicator Is Never/Always On

Pinpoint Test V: The 4X4 High Indicator Is Never/Always On





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

Possible Causes
- 4WD control module
- instrument cluster
