Distance sensors: Diagnostics
The control module monitors its own functionality and inputs and outputs.
The distance sensors are checked 10 times/second in modes 2 and 3.
In the event of a fault in a distance sensor or its communication with the control module, the following diagnostic trouble codes are generated:
DIAGNOSTIC TROUBLE CODES REFERENCE
| Diagnostic trouble code | Sensor | |
|---|---|---|
| B2906 B2916 B2926 B2936 |
RR RRC RLC RL |
Communication cable shorted to B+ |
| B2907 B2917 B2927 B2937 |
RR RRC RLC RL |
Communication cable broken or shorted to ground, or break in supply |
| B2908 B2918 B2928 B2938 |
RR RRC RLC RL |
Open ground circuit, short to ground or B+, or internal sensor error |
| B2909 B2919 B2929 B2939 |

Internal fault |
| B2950 | Sensor power supply shorted to ground | |
- RR: Right-hand outer sensor
