Sensor power supply
â–¶ How to fix
Make sure that there are no short circuits or breaks in any of the affected sensor circuits. Measure on the following coordinator pins: On earlier models of coordinator: 69, 91, 93, 97, 98, 99 and 100.On later models of coordinator: B13, C28, C29, C30, C19 and C12.
What you'll see
No driver-visible symptom recorded.
System reaction
No system-reaction text recorded.
Diagnostic depth
Detection
The coordinator supplies power internally to a number of analogue sensors. The fault code is generated if this voltage level has deviated from the permitted level.
Possible cause
Short circuit or open circuit in one of the analogue sensors that are connected to the coordinator.
