| IDS can not communicate with vehicle |
|
Vehicle type:D3 tdv6
Chassis no: SALLAAA137A41xxxxx
PROBLEM; Vehicle had a front end damage in an accident and was rebuilt.
1,New engine ECU was fitted
2,Engine wiring loom repaired
3,Collection of engine parts fitted (from salvage )
NOW; The guy who helped building the vehicle sought help from a friend who had an IDS machine to try to programme the engine ecu to the immobilizer but failled.( what ever they were doing am not sure if they may have accessed the ecu more than 15 times rendering the ecu lock out.they gave up.)
THEN; I took the vehicle to local land rover.
THEIR REPORT; Connected IDS to chech for fault codes & IDS wont communicate with ecu/vehicle.
Checked and tested battery condition.
Checked earth wires from battery positive.
Tested wiring and power supply to CJB from batt to body control module.
Tested wiring from CJB to engine.
Checked and tested wiring from body control module to engine.
Checked communication from instrument cluster to CJB by stripping front dash
inorder to test wiring.
Diagnosed engine wiring harness as fault and needs replacement as step one.
I was then given a hefty quote which i declined( supply & fit eng wiring harness) I just paid for labour.
NOW; I towed the vehicle home and reworked on the wiring loom.
MY RESULUTION; To buy my own FAULTMATE MSV-2 to avoid back and forth towing plus charges 4 diagnosis by the dealer.
QUESTION; 1,Why would or what could cause the vehicle not to communicate with the IDS?
2,Could a repeated trials to enable the eng ecu cause it to lock out.after 15x?
3,Would faultmate be able to programme the eng ecu to comms with the immobilizer?
NB; Every thing else in the vehicle works fine exept it wont even turn the starter just a click on the front passenger foot well.no fault codes showing.
I may replace the entire engine wiring loom if am lucky enough to get it else where.(salvage)
Regards
Tinto

Does your temperature gauge read as if it's stuck at the top ? And red warning light on ? G4 Gone ...but not forgotten

No, the Temp guage moves just a bit to the blue mark when key is ON.(outside temp 27dec.) no other red light except batt,oil,park and seat belt.after all lights off on instrument cluster check.

A few questions to help me answer you.
Was the engine ecu BRAND NEW ? and why did you have to fit another ?
Are all the ecus and keys on the car from that car apart from the engine ecu ?
What is the resistance over the CAN wires at the diagnostic port with the battery disconnected ?
pin 3 to pin 11 resistance is ?
pin 6 to pin 14 resistance is ?

There is currently an issue programming brand new Continental PCMs. The ECUs have come with some infomation missing that SDD (IDS) requires. Dealer Diagnostic Support have a fix for this in the UK, but not sure when the fix will be officially released.

Is there still 12v at the OBD plug? 2015 BMW i3 REX

Hi Pete
The engine ECU was bought brand new from TLO and it had a new part number.original part number was no longer in production.we just had a feeling it may have been damaged internally.
All ECUs and keys are from same car except for AIR BAG MODULE & GEAR BOX ECU.
Resistance at diagnostic port between pin 3 and pin 11=60.2 Oms
pin 6 and pin 14=62.1 Oms

Hi
Ok perfect with the new ecu as a used one cant easly be re used on another car without virginising.
The CAN resistance is perfect on both the HI speed and LOW speed busses, Assuming you have as suggested above by CJM625 12V on pin 16 and GND on pin 4 & 5 of the OBD plug i cant see why IDS would not communicate.
Did you test the car with the old ecu,or did it look damaged externally ?
Did the new airbag module come from a crashed car ?
It is looking as though you may need to have diagnostics available your self as you say to save the back and forth.
The MSV2 will program the ECU and also make the fuel lift pump configuration you need assuming all other is correcton the car.

Hi CJM625 and Q86ARR
Sorry, i will check later.from which pins should i check for voltage?
I very much agree with you that maybe the problem could be with the new ECU bug.in the mean time what could be the solution.

Pin 16 is 12V
Pins 4 & 5 are chassis GND
Across the 2 should give you the battery voltage.
If it were an IDS bug of which ive never had on a D3 it should still have connected to the car and at least failed during the process of writing. That said its hard to actually know what went off if you were not using the tool your self.

I did check using pin 16+4=12.22V
pin 16+5=12.22V
your reply above, did you mean to say pin 16 not pin six?
Both Gear Box and Air Bag Modules were from a Non crashed vehicle

A few months ago I was trying to change my MY06 for a new MY08 instrument cluster so that I could get the lights-on and clock-in-dash features.
It was a new instrument pack and therefore needed the CCF data (with VIN etc) writing back into it to enable it to work.
Unfortunately, my Faultmate wouldn't do this as with my Single Vehicle license, it obviously saw a blank VIN in the instrument pack and wouldn't work.....(this was corrected by BBS within a couple of days and they released new software to everyone) - the new software checks for valid VINs in other modules where this data is stored and therefore will work assuming that you replace one ECU at a time (no such restrictions for Multi Vehicle licenses).
Anyway, the point of this long-winded explanation is that upon powering up the new instrument cluster, I immediately got suspension errors on the dash and when trying to start the engine, all I got was a "click" from the BCM (passenger footwell).
I replaced the original instrument pack (D3 immediately started with no errors) and read the fault codes which had (stored in the suspension control module) a "VIN mismatch error".
What I mean is that a mis-matched VIN number in one or more of the ECUs could give you this type of non-start error......
I hope you understand what I mean  2006 Discovery 3 TDV6 SE Auto Buckingham Blue

Yes pin 16 sorry it was a typo 
Basicly we have power, gnd and comms to the OBD port so their is no reason IDS should not communicate to the cars modules.
I think its time for the MSV2, and your self diagnosis.
