Re the TPMS fault (again, lost comms) I have looked at the ECU, located in the rear RH cubby, it seems fine. So, in my tiny brain, I am thinking that this could be causing my current problems. Correct me if I am wrong, but I assume this is how it can work? the module is interrogated and found to have no faults stored, but the module has not detected a fault due to a poor connection further down the line. After investigating and finding numerous dodgy connections, I put the lack of fault detection on IId down to these poor contacts -i.e. When I had issues with door locks not responding, faults on door connections etc a month back, I found that the IID did not detect any faults. Regarding my transmission problem, I intend to crawl underneath later, and check the plug connections/ loom etc around the 'box, as a starting point. Steve, is it not better to discuss the problem/likely causes on the forum? Might save GAP some repeat emails if its something that all users should know and may come across in their future use? BUT again, when I look at the TPMS ECU with IID tool, it says ' lost comms with ECU' Last but not least, I have fitted new TPMS valves -gen new 2013 units- and am still getting the TPMS warning light, despite following the instructions regarding a number of attempts at the minimum running period to register the new valves.
Also I am using the tool with the handbrake off and the engine running, as recommended. I have had a good look at the pins and connectors, all seem fine, as it mentions this in a previous post. Then ' cannot read CCF' comes up and it won't go further within that menu.
Next problem, tried to look at CCF, gets the message. When I tried to do a 'clear all faults', the unit got to around ECU no 18 and then showed 'update failed' then carried on clearing faults. I have a transmission problem, so plugged in my IID tool to check for any DTCs etc, but when I scanned the transmission ECU, got the message 'no comms with ECU'. Hi Steve and all, thought it worth posting my query on here, the answers may be useful to others.
