Signal Too Low. Intermittent Fault

Signal too low. Intermittent fault

Checking the wires
Check wires between damper motors for an intermittent short circuit to voltage supply, as described in Checking wiring and terminals. Intermittent faults Checking Wiring and Terminals. Intermittent Faults , and an intermittent short circuit to ground, as described in Checking wiring and terminals. Intermittent faults Checking Wiring and Terminals. Intermittent Faults.
Do the necessary corrective action.

Self-adjustment




Limit positions for damper motor self-adjustment

Choice of climate control
1. Electronic climate control (ECC)
2. Manual climate control (MCC) / Standard (STD).

Select the type of climate control.

1 - Limit positions for damper motor self-adjustment 1

2 - Limit positions for damper motor self-adjustment 2

------------------------

Limit positions for damper motor self-adjustment 1

Hint: After replacing the control module or shutter motors, and when a shutter motor or link has been removed, carry out self adjustment to define the shutter motor limit positions.




- Ignition off
- Reinstall the connectors, components etc.
- Ignition on.
Activate the self-adjustment. Wait at least 30 seconds.
Ignition off for at least 1 minute.
Start the engine.

Information

Fault-tracing information
If the fault is intermittent, do not verify fault-tracing if the fault does not recur.
It is possible to view the information again, or leave fault-tracing for this diagnostic trouble code (DTC).

Do you want to view the information again?

Yes - Attempt New Test

No - Exit fault-tracing
