beschikbaar stelde, kwam ik nog iets handigs tegen. Je kunt het HVAC-systeem een self diagnosis laten doen. Daarvoor moet de auto aan staan en moet je op het bedieningspaneel de knop OFF ingedrukt houden en vervolgens snel 4 keer achter elkaar drukken op Mode-knop (die zit er rechts van, waarmee je de luchtstroomkanalen verandert). Het scherm knippert 3 keer met alle icoontjes en komt vervolgens met eventuele foutcodes (zie tabel hieronder). Vervolgens kun je met de OFF-knop de self diagnostics weer afsluiten en terug naar normale werking gaan. In de workshop manual staat dit allemaal vanaf pagina 1170 beschreven.
Erg handig tijdens bijv een proefrit of als je garantie bijna verloopt. Ik heb helaas niet zoveel geluk gehad, na een nieuwe condensor even later een nieuwe verdamper is nu de klep/motor voor ontwasemen van de voorruit geblokkeerd. Hij geeft hier code 34 aan.
Omdat ik in het topic nog niet iets terug kon vinden over de HVAC self diagnostics, hier maar gelijk de hele tabel met codes
| Code | Failure Details | Remarks |
| 00 | Normal | |
| 11 | Interior Temperature Sensor Disconnection (OPEN, INCAR F/B Voltage ≥ 4.9V) | |
| 12 | Interior Temperature Sensor Short Circuit (SHORT, INCAR F/B Voltage ≤ 0.1V) | |
| 13 | External Temperature Sensor Disconnection (OPEN, AMBIENT F/B Voltage ≥ 4.9V) | |
| 14 | External Temperature Sensor Short Circuit (SHORT, AMBIENT F/B Voltage ≤ 0.1V) | |
| 17 | Evaporator Temperature Sensor Disconnection (OPEN, EVAP F/B Voltage ≥ 4.9V) | |
| 18 | Evaporator Temperature Sensor Short Circuit (SHORT, EVAP F/B Voltage ≤ 0.1V) | |
| 19 | Temperature Control Actuator Feedback Disconnection/Short Circuit (OPEN/SHORT). SHORT Range [TEMP F/B Voltage ≤ 0.1V]; OPEN Range [TEMP F/B Voltage ≥ 4.9V]. | |
| 20 | Temperature Control Actuator Motor Constraint. The code is not displayed if both the target and constraint ranges fall within the MAX COOL range [0.1V < TEMP FB voltage ≤ 0.5V] and MAX WARM range [4.5V ≤ TEMP FB voltage < 4.9V], because there is no longer any constraint. This prevents MAX WARM and MAX COOL from displaying code 20 due to error margins of the actuator and FATC. | If the actuator cannot reach the desired control position in 10 seconds, it is deemed constrained. |
| 21 | Driver Seat Mode Actuator Feedback Disconnection/Short Circuit. SHORT Range [DR MODE F/B Voltage ≤ 0.1V]; OPEN Range [DR MODE F/B Voltage ≥ 4.9V]. | |
| 22 | Driver Seat Mode Actuator Motor Constraint. The code is not displayed if both the target and constraint ranges fall within the VENT range [0.1V < DR MODE FB voltage ≤ 0.5V] and DEF range [4.5V ≤ DR MODE FB voltage < 4.9V], because there is no longer any constraint. This prevents VENT and DEF from displaying code 22 due to error margins of the actuator and FATC. | If the actuator cannot reach the desired control position in 10 seconds, it is deemed constrained. |
| 23 | Auto Defog Sensor Disconnection | |
| 24 | Auto Defog Sensor Short Circuit | |
| 25 | Internal/External Air Actuator Position Sensor Disconnection/Short Circuit. SHORT Range [INTAKE F/B Voltage ≤ 0.1V]; OPEN Range [INTAKE F/B Voltage ≥ 4.9V]. | |
| 26 | Internal/External Air Actuator Motor Constraint. The code is not displayed if both the target and constraint ranges fall within the FRE range [0.1V < INTAKE FB voltage ≤ 0.5V] and REC range [4.5V ≤ INTAKE FB voltage < 4.9V], because there is no longer any constraint. This prevents FRE and REC from displaying code 26 due to error margins of the actuator and FATC. | If the actuator cannot reach the desired control position in 10 seconds, it is deemed constrained. |
| 27 | Passenger Seat Mode Feedback Disconnection/Short Circuit. SHORT Range [PS MODE F/B Voltage ≤ 0.1V]; OPEN Range [PS MODE F/B Voltage ≥ 4.9V]. | |
| 28 | Passenger Seat Mode Actuator Motor Constraint. The code is not displayed if both the target and constraint ranges fall within the VENT range [0.1V < PS MODE FB voltage ≤ 0.5V] and DEF range [4.5V ≤ PS MODE FB voltage < 4.9V], because there is no longer any constraint. This prevents VENT and DEF from displaying code 28 due to error margins of the actuator and FATC. | If the actuator cannot reach the desired control position in 10 seconds, it is deemed constrained. |
| 33 | Defrost Feedback Disconnection/Short Circuit. SHORT Range [DEF F/B Voltage ≤ 0.1V]; OPEN Range [DEF F/B Voltage ≥ 4.9V]. | |
| 34 | Defrost Air Actuator Motor Constraint. The code is not displayed if both the target and constraint ranges fall within the OPEN range [0.1V < DEF FB voltage ≤ 1.9V] and CLOSE range [2.8V ≤ DEF FB voltage < 4.9V], because there is no longer any constraint. This prevents OPEN and CLOSE from displaying code 34 due to error margins of the actuator and FATC. | If the actuator cannot reach the desired control position in 10 seconds, it is deemed constrained. |

Je hebt gelijk, hij moest nog verversen. Na 100 meter lijkt hij al uit te lezen maar pas iets later ververst het daadwerkelijk. Met de OBD de bandenspanning uitlezen had ik nog niet geprobeerd, ga ik ook eens doen.
