Safety Warning
DIY auto repair can cause serious injury, fire, or vehicle damage. These guides are for informational purposes only. Always follow OEM torque specs, wear PPE, and consult a certified mechanic if you are unsure. You are solely responsible for your safety.
Control Module Resets
Using the DISplus or GT1 a Test Plan may be run to check number of control module resets for each control module on the MOST bus.
A control module with 0 (zero) resets has performed no reset, is not installed in the vehicle, or can not be found with the diagnostic equipment.
The control module with the highest number of resets is the most probable cause of a fault with the MOST bus.
Below is an example of a readout from the DISplus or GT1:
| Head-Up Display | 15 |
| CD Changer | 0 |
| Headset Interface | 0 |
| Amplifier | 0 |
| Video Module | 0 |
| Telephone | 0 |
| Satellite Radio | 0 |
| Nav System Japan | 0 |
| MASK (or CCC) | 15 |
