  1. Very pleased to hear you've got it sorted.
  2. Hi Alan, Thanks for the kind comments. It was a bit of a headache but I'm lucky enough not to need the car on a daily basis so I have time to tackle it myself. Others aren't that fortunate. As an amendment to my resistance readings shown above, the manual states that the resistance between pin 1 and pin 6 in connector CA269 should read less than 5 ohms (not the 0.1 or 0.2 I mentioned...don't know where I got that from!!) On arrival. I tested the new actuator resistance and it measured 0.36 ohms. NO NEED TO CODE. I have read that the actuator needs to be coded to your car by Jaguar...
  3. Hi Robbo, I understand now that it appears far more involved than a simple parking brake issue. I'm sorry I am unable to offer any insight. However, there are many people on this forum who are extremely knowledgeable who may be able to shed some light on this problem for you. I know it can be a real worry and incredibly frustrating trying to find the cause of an issue but there is no harm in trying and much better than throwing money at it. In my experience, very few 'professional' car repairers want to admit they do not know what is wrong with your car and it usually ends up costing you
  4. Hi Robbo, Thanks for your comment on my thread - Yes, I do love my S type (owned since 2010) and will continue to do so...but sometimes it tests me greatly. 🙂 I don't know if I can assist or not but I'm a little confused as to why the auto electrician suspects the electronic parking brake problem would be due to problems with wiring under your front bumper.? Maybe this is simply down to my ignorance. As I said, I may not be able to help but may I ask a couple of questions? What exactly is happening with your electronic parking brake (EPB) when you switch on the ignition? What me
  5. Brand new actuator fitted. All has been fine for the last 2 days. It appears the problem if finally sorted. HOORAY!!!!!! I bought the brand new, genuine Jaguar EPB actuator from Roger Young Ltd for £255 including VAT and delivery (UK) They do state that this part will need to be encoded to your car. This information apparently comes from Jaguar. I have not had this problem and the new actuator worked instantly. All I needed to do was press the foot brake and hold it down whilst engaging the park brake switch (as you do to re calibrate after battery disconnect or new rear pads
  6. As per my other thread re this problem, I managed to test the actuator this morning. The Actuator connector CA269 (pins 1 and 6) should give a resistance of 0.1 or 0.2 ohms but my tests showed an open circuit so I have now ordered a brand new Actuator. It appears that all along there has been some sort of intermittent wiring fault within the actuator. I'll update this post once the new actuator has been fitted.
  7. After continuing EPB problems and DTC C1785, I managed to detach the actuator connector CA269 and test the resistance between pins 1 and 6 (as stated in the Manual) The resistance readings should be 0.1 to 0.2 ohms but I'm getting the continual 1 on the left side of the screen showing resistance out of range, ie open circuit (on any Digital Multimeter resistance setting) . I have now purchased a brand new Actuator and will update again once fitted. Fingers crossed.
  8. Update - problem still present. DTC C1785. Parking Brake actuator open circuit. Look like I'm going to have to replace the actuator for a 2nd time in 12 months. It's a love/hate relationship with My S Type and at the moment it's heavily leaning toward the hate!! For the first time in over 11 years I am considering a parting of the ways.
  9. Hi Mad Martyn, I've only just seen your question but hopefully this will assist. (see below link) I changed my headlight main beam switch last year so this should assist with the other side too. I found this on Youtube and is was most helpful. https://www.youtube.com/watch?v=6NLCS75zrSw
  10. As a final update ( I hope) it would appear that the fault lay with one of the small connectors within the black (left side) multi-plug of the EPB Module. This multi-plug is is what carries the power down to the EPB Actuator under the car. I am guessing that with the numerous plugging and unplugging of this connector when I was trying to sort out the faulty actuator last year, one of the pins opened up its corresponding 'female' connector and caused an intermittent loss of signal. All appears fine now. Fingers crossed.
  11. Hi Joe, Many thanks for the advice. I am able to eliminate EPB actuator as being faulty because the actuator works both on and off when connected direct to the battery (connecting to red/white and green/white wires of left side EPB Module multi-plug)This also suggests no wiring issues between the Module plug (black - on left) that takes power down under the car to the actuator. It appears to be sorted (for the moment at least) after tightening up the female side of the pin plugs within the module connectors - maybe they had become slightly loose with the numerous plug ins and plug outs w
  12. Many thanks for the responses and sound advice. The fault DTC C1785 has returned. Each day when I go to start the car I get the same C1785 DTC. Today, wiggling wires and removing/replacing epb plus did not cure it. I have removed, checked and cleaned all fuses relating the the Parking Brake but not relays. I'll check those too. Dam - yes there has been damp in the boot recently (now dried out) but I believe that was from leaking water/ coolant top up bottles I kept in the boot. However, I will monitor to see if any of this abundance of rain is finding a way in. The batter
  13. I have resolved this issue now - it would appear to have been loose wiring or maybe damp in the boot area...not sure which but after drying out the boot and pushing all the EPB module connections in from the rear of their multi plugs, the EPB worked again. I don't know why this didn't work the first time I wiggled the wiring but I'm just glad it's sorted now.
  14. Problem solved.....or should I say 'sorted' as I'm not entirely sure what I did. Let me first say that I have an icarsoft i930 code reader (a must for Jag owners I would suggest - it has saved me a fortune over the last few years) I had already replaced the actuator in Feb 2020 with a used unit. When this most recent fault C1785 occurred a week or so ago, I purchased a new Bosch S5 battery and a replacement (used) EPB Module that had the corresponding codes and revision "E" the same as mine Neither of these steps altered the C1785 DTC and the fault remained.
