Test H: The 4X4 Shift In Progress Warning Is Inoperative

PINPOINT TEST H: THE 4X4 SHIFT IN PROGRESS WARNING IS INOPERATIVE

H1-H4:

Normal Operation
The four wheel drive (4WD) control module sends the instrument cluster a message over the high speed controller area network (HS-CAN) communication bus lines when the 4WD system is in the process of shifting out of two wheel drive (2WD) and has not yet fully shifted into 4x4 high, 4x4 low or 4x4 auto. Once the shift is completed, the 4WD control module removes the 4x4 shift in progress message and sends a new message to turn on the applicable reconfigurable telltale indicator.

Possible Causes
- Instrument cluster configuration
- 4WD system
- 4WD control module
- Instrument cluster
