Failsafe Engine Mode message. Was intermittent - no problem.

Customer Question
Failsafe Engine Mode message...

Failsafe Engine Mode message. Was intermittent - no problem. Now hard fault and preventing the engine from starting.

Mechanic's Assistant: Will the headlights turn on? Is the battery fully charged?

Yes and yes.

Mechanic's Assistant: What is the model/year of your Jaguar?

XK8 1998

Mechanic's Assistant: Are you fixing your XK8 yourself? What have you tried so far?

I asked around in work for an OBDII code reader and got 3 of them. Tried them all and they all said there was no fault code present.

Mechanic's Assistant: Anything else you want the mechanic to know before I connect you?

Can't think of anything else right now.

Hey how are you

The OBDII reader only capable of reading engine fault codes and limited at that on Jag

if for example anti theft ,bcm , etc modules has fault in them it want see them .

Have you tried a Master reset and see if it was glitch

make sure u have a good 12 volts battery and good 14 volts when running with loads on

Master reset Procedure

1- Disconnect Battery Cables ( Negative & Positive Cables )you can use any electrical wire as an extension if battery cables don't reach .

2- Hold cables Together for 60 secs ,then let go

3- Wait 30 minutes

4- Make sure all doors are closed

5- Reconnect battery Cables

6- Lock & unlock the vehicles using the key from driver door side (if you have a key fob with no blade key, just lock & unlock using the key fob buttons)

7- Enter the vehicle and attempt to start

can you get your hands on jag capable scanner ?

lets start here and we go from there

Please let me know

Thank You
