Scan tool diagnostics
| Scan tool diagnostics |
The Sensonic system communicates with the Scan tool diagnostics instrument via pin 38.
Communication is two-way, i.e. both output and input signals are used.
The Scan tool diagnostics instrument can communicate with the Sensonic only when the ignition switch is in the ON position.
The fault memory of the control module will not be cleared if the control module power supply is interrupted.
When a fault has been rectified, the diagnostic trouble code must be cleared by means of the Scan tool diagnostics instrument. If this is not done, the fault will be retained as intermittent.

|
A diagnostic trouble code generated in the Sensonic system will never be cleared by itself. Old diagnostic trouble codes may therefore occur. |
