Faulty ID
Faulty ID
Checking the function
- Engine running.
Check that all the functions can be activated via the lower switch.
Hint: Where applicable, the LED on the lower switch must be lit when the function is activated.
Are all functions activated?
Yes - Fault-tracing information
No - Checking the switch identity
-------------------------------------------------
Checking the switch identity
- Ignition on.
Note! The switches can be placed in any position in the climate control assembly (without internal order). The position of the switches must be taken into account when fault-tracing with VCT2000.The switch furthest to the left in the climate control assembly corresponds to no. 1 in VCT2000. VCT2000 then follows the numbering in order to the switch furthest to the right, which is designated no. 7.
Read off the identities of the switches. Check that the read off identity corresponds to the switch marking for its position in the dashboard environment panel. If the identity does not correspond to the marking, this indicates a defective switch.
Remedy as necessary.
Was a fault detected?
Yes - Verification
No - Checking the switch status
-------------------------------------------------
Checking the switch status
- Ignition on.
Note! The switches can be placed in any position in the climate control assembly (without internal order). The position of the switches must be taken into account when fault-tracing with VCT2000.The switch furthest to the left in the climate control assembly corresponds to no. 1 in VCT2000. VCT2000 then follows the numbering in order to the switch furthest to the right, which is designated no. 7.
Read off the status of the switches. Check that the read off status is OK for each switch. If the status is not OK, this indicates that the function of the switch is not in the Car Configuration.
Was a fault detected?
Yes - Information
No - No Fault Found
-------------------------------------------------
Information
The fault is probably because the functionality of the button is not in Car Configuration. This is remedied by ordering and downloading the missing functionality.
Continue - Verification
-------------------------------------------------
Fault-tracing information
The fault is probably the result of a damaged, intermittently defective or missing switch. If the fault is intermittent, it has been registered previously but is no longer present.
Intermittent faults may be caused by interference at start up of the control module. Intermittent faults may also be caused by other types of intermittent faults. The fault is evaluated depending on how it occurs.
Continue - Information
-------------------------------------------------
Verification
Hint: After carrying out the repair, check that the fault has been remedied.
- Ignition off.
Note! Wait at least 1 minute before "Ignition on". This is to allow the climate control module (CCM) to carry out a new diagnostic.
- Reinstall the connectors, components etc.
- Ignition on
- Read off diagnostic trouble codes (DTCs).
The fault is no longer present if the status of the diagnostic trouble code (DTC) has changed to intermittent.
Does the status change?
Yes - VERIFIED
No - VERIFICATION FAILED
------------------------
VERIFIED - Fault Found
VERIFICATION FAILED - Information
-------------------------------------------------
Information
Fault-tracing information
The fault should have been detected and remedied. As this is not the case fault-tracing has failed.
Exit fault-tracing for this diagnostic trouble code (DTC) or make another attempt.
Do you want to exit fault-tracing?
Yes - FAULT-TRACING FAILED
No - Attempt New Test
------------------------
Attempt New Test - Checking the function
FAULT-TRACING FAILED - No Fault Found
-------------------------------------------------
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 - Fault Found
------------------------
FAULT FOUND - Fault Found
Attempt New Test - Checking the function
