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 |
HEAD-UP DISPLAY
Note. Resets at a rate of less than 10 may be normal for a control module. When the number of resets is less than 10, this is only an indication on the possible cause of a fault. The control module should generally NOT be replaced with less than 10 resets.
