With the fan speed you can have it on max then out of no where it will stop for a few seconds then cut back in. From what i been reading on the workshop manual might be PCM related
With the cluster it's the main gateway module for mid and high speed can bus.
Cluster also gives you icc information eg what station or track you are listing to in the main screen. (Does not work with the mk2 icc installed eg AM comes up with MP3 TR1, FM says AUX)
The ASL Board is soldered in to the icc (FDIM Touch screen) can bus pins.
I still have the fitting instructions somewhere if you want to have a look ?
I've done a fair bit of reading in to this from i can personally see the main issue is the software in the clusters
Based on the tech documents, the HIM and PCM work very closely to protect the HVAC system. The PCM can request the aircon system to disable if it detects an issue or thinks an issue is about to occur. Both HIM and PCM are on HSCAN.
So I think you might be experience the above?
Cluster is the network gateway, thats actually a pretty big job.
The HVAC docos explain:
Inputs from ICC pass through to cluster… then from cluster to HIM.. HIM makes the required changes.. then passes info back to display on ICC (Face Display Module FDM)
Also, Cluster receives the data from FDM in regards to illumination. So that makes sense why illumination works with MK2 cluster.
So it sounds like alot of mismatch going on as the MK1 and MK2 clusters pickup and send different data.
So the MK2 ICC sends out saying its now FM.. but the MK1 Cluster thinks the message it received means Aux.
Yeah, fitting instructions and any information you have about the ASL board would be great. Does it have a description for what its actual purpose is?
Trying to find the instructions for the ASL module. The Actual purpose is to use a MK1 him module to read the fdim so all your heater settings work like normal
