BeZerKaNZ 1 Report post Posted December 28, 2018 (edited) Climate control system IHKA faultSo i did something regrettable which was driving around when i had temporarily disconnected the IHKA climate control system. Why i did this is another story. Anyway when i put everything back together again and reconnected it i came up with a code fault for every sub system for the module. I tried clearing codes, resetting module, and disconnecting battery to reset but nothing seems to work. The AC doesn't work anymore, and it seems like some components within climate control are no longer working. I.e heat exchanges, fan control, stratification. All I get is uncontrolled air flowing through.Is there a specific reinitialization sequence to get the climate control working again?The code faults are:KLIMA 9C70: ISupply,SZMKLIMA E708:KLIMA 9C59: IEvaporator termperature sensorKLIMA 9C5A: IHeating heat-exchanger sensor, leftKLIMA 9C5C: IHeating heat-exchanger sensor, rightKLIMA 9C60: ISZM button 1KLIMA 9C61: ISZM button 2KLIMA 9C62: ISZM button 3KLIMA 9C63: ISZM button 4KLIMA 9C65: ISZM variant coding 2 Edited December 30, 2018 by BeZerKaNZ Quote Share this post Link to post Share on other sites
BeZerKaNZ 1 Report post Posted December 30, 2018 Resolved: I went back and check everything and found that a connector wasn't connected properly in the IHKA module. What I discovered (I'm guessing here) is that the Heater control valves did not operate which caused the engine to overheat and begin detonating. Anyway I plugged in the loose harness and everything went back to normal, detonation immediately stopped. Quote Share this post Link to post Share on other sites
