The car was Again impossible to start (it has a silly button start than does not allow ignition on without cranking) so I tried Gap's reset in the service menu. But all my attempts give me that E5 , no success

As sources in this forum and the diagram suggest a link between this error and the recently changed starter I have controlled the battery terminals, said starter's power supply, solenoid cable etc. All is well
It turns but it does not start

I also checked all the states in the airbag module

Just found no reason for the 'crash'
I add some pages if possible

Then I thought immediately that it is the sequence ignition - ignition off - Ignition which does not work because it is impossible to put the ignition without the starter engaged.
So I tried it without the starter relay (no it gets angry)

And without the fuse of the starter to get the ignition state without starting.
It does not generate any other error but always it is in E5 if I do the procedure.

This one came back once


I also checked the fuses etc. I even cut the brown cableI even cut the brown cable that indicates the crash and I reconnected it.

Nothing to do

The unique way to start the car is by pushing it back a bit.
After it starts but it will go another time on strike while driving for no logical reason from time to time

I studied electrical diagrams for hours.
The crash sensors are not there, nor in the workshop manual.

They also say that there is a procedure for this error with specific test cases but they do not elaborate any detail.

I hope you have an idea.

I must admit that I spent my whole Sunday with this and nothing

I have a permanent crash error that I cant clear either - its a known software fault in my code reader. Therefore, it COULD be a red herring so spend some time thinking about the other codes you have got.

You definitely need to make sure you have a good battery and that you fit an additional earth lead, if not already fitted, preferably straight to the starter.

Go around and clean up your earth connections in the engine bay and on the rear end including tailgate.

Lastly, check your wheel bearings as a failed bearing can throw up ABS faults.

Good luck and let us know how you get on. FL2 HSE Auto Galway Green

From what I know, the crash input error is not erased by conventional means, but it needs a specific procedure to be run inside dealer's SDD.
IIRC, you need to put the BCM into extended diagnostic mode, authorize yourself into it and then write a zero value to a specific memory location.

To add to the above, crash codes as I recall are written into ROM, and despite many dubious and downright dodgy traders on FleaBay et al who claim that they can erase these short term, my understanding (correct me if I am wrong) is that the moment that the BCM detects a voltage drop, then these codes are dumped straight back into the main ECU.

Apparently it works on a similar basis as the mileage tamper preventative, which is hidden away somewhere also in ROM to stop aforementioned dubious traders frigging about with things permanently....

I don't understand your statement that you can't turn the ignition on without cranking the engine.

Of course you can do that, just don't depress the clutch pedal (if manual) or brake pedal (if auto) & press the button for a couple of seconds. (Now Sold). 2008 Freelander 2 (Nazca Sand) SE TD4 Auto. Statutory write off & on WOVR for hail damage but still road legal.

There is a main earth lead from the top of the body to the tailgate.

A lot of the electrical codes are about things down the rear so check the wiring for damage under the rear floor etc. FL2 HSE Auto Galway Green

Here is what I would do if I had the problem that you are having

1. Remove the B+ terminal

2. Charge the battery

3. check the voltage it should be over 12.6 Volts

4. has it been at least 2 hours since B+ was removed? (if not then wait 2 hours if yes then go to next step)

5. Attach B+

6. Close the hood and all of the doors

7. Lock and unlock the vehicle

8. Enter the Vehicle (Do not touch the brake)

9. Count to 10

10. Dock the Key (Do not touch the brake)

11. Count to 10

12. Touch the Brake briefly (A relay may click)

13. Remove foot from brake

14. Press the start/stop button briefly (Did anything turn on?)

15. hold the start/stop button for 8 seconds (Did anything turn on?)

16. Un-Dock the Key

17. If nothing turned on repeat steps 10 to 16 three times

18. If the dash board and Radio and Navigation turn on then at step 15 press the brake and push start/stop and the engine should start


If the Start stop button is bad then the vehicle won't start and you will not be able to activate the other power modes.

If the Voltage at the battery is too low the modules can get latched up and stop functioning (Disconnecting power for 2 hours and then applying >12.6 volts should clear this problem)

Note: as Alex pointed out the crash mode bit may have to be reset.


One last check - if you enter the vehicle without the key can you turn on the radio? Press the power button for 5 seconds?

Also press the button on the instrument cluster with the Key out and the Miles Traveled should be displayed?

Good luck

Thank you that is very good advice

Peter you are a star.

I have already asked the owner to disconnect the battery.
It is only a month old, but I said please charge it well during these 2 hours
Then I will translate your recipe.

After that if all fails I'll drive there and see what the tailgate earth and fuel pump is like Technician in Guanacaste.
Always after documentation.. will help those who look for it. Free of course

PRINCIPLES OF OPERATION

Starting Process

The ECM will only allow engine crank, spark and injector functions when the following conditions are met:
* A hardwired Park/Neutral signal is received from the Transmission Control Module (TCM)
* A hardwired ignition signal is received from the CJB
* A hardwired crank request signal is received from the CJB
* Encrypted data exchange between the instrument cluster and the ECM is verified.

Before the CJB will send the hardwired ignition signal, it must satisfactorily complete the following:
* Exchange encrypted data with the start control module to validate the remote handset.

Additionally, before the CJB will send the hardwired crank request signal it must receive the following signals:
* Brake signal from the speed control inhibit switch
* Hardwired transmission in Park (P) or Neutral (N) signal from the selector lever assembly.

With the remote handset inserted in the start control module and the stop/start button is pressed, the start control module issues battery voltage high signal on the LIN bus connection to the CJB and the fuel pump is run for 2 seconds to prime the fuel system. The CJB uses this signal together with the stop lamp switch signal and issues a crank request message on the high speed CAN bus to the ECM.

The ECM, on receipt of the crank request message, then provides a power and ground supply to the starter relay in the BJB, closing the relay contacts. Battery voltage is supplied via a fuse through the starter relay and is passed to the starter motor solenoid coil. The coil is energized, closing the solenoid contacts and allowing a fuse battery voltage supply direct from the battery to operate the starter motor and crank the engine and simultaneously switch the fuel pump on.

The ECM operates the starter motor until the engine starts which is determined by the engine speed exceeding a pre-determined value.

Auto Start

The ECM has an auto start function which allows the engine to continue cranking if the stop/start button is released. The starter motor will operate until the engine starts or a pre-determined period of time has elapsed which is based on engine coolant temperature. Low engine coolant temperatures allow longer crank times. If the engine does not rotate or the engine speed is low, the ECM removes the power supply and ground from the starter relay stopping the crank process.

Start Prevention

Operation of the starter motor will not be allowed or will be interrupted if:
* The engine is running and the engine speed has exceeded a predetermined speed
* The encrypted data exchange between the instrument cluster, ECM, CJB and start control module has failed to:
-----> Identify the remote handset
* The gear selector lever is not in the park 'P' or neutral 'N' position.
----> The signal is determined from:
--------> a signal from the TCM and also the transmission mounted position switch
* The brake pedal is not pressed.
