"17978 (P1570) Engine Start Blocked by Immobilizer"

What does this stored code mean?

Car runs just fine, but when it was checked recently, this came up...

Means at some point, you tried to start the engine but the immobilizer said "No!". Not uncommon. No cause for concern unless it comes back regularly or engine won't start.

Hi,

If car starts ok, it's not a problem. Probably tripped the code on a cold day with hard starting problems and low voltage.

I am having the same problem but the car will not start. I also cannot erase that code.

Any ideas?

Does the engine start at all and shuts down immediately again, or doesn't it even start? Checked relay 109? Are the instrument cluster immobilizer meas. blocks plausible?

The engine starts and shuts down 2 secs later. Have not checked 109. How do you do that? Would that stop you from clearing a code? I have not checked meas blocks in instrument cluster. What shoud they read?

No clue why, but it looks like your ECU lost it's adaptation to the instrument cluster. Not 100% sure, but your 2003 model should have IMMO-3, right?

Immo-3 knows your car's VIN. Access 17-Instruments (or separate 25-Immobilizer on vehicles that are set up that way) and look at the first "Extra" field.

If you see something like: "Immo-ID VWZ7Z0W0648696" You've got Immo-2 (or maybe even Immo-1 in earlier non-US models).

If you see something like "WVZKB58001H231169 VWZ7Z0W0648696" You've got
Immo-3. The first 17-digit string is the VIN. The second 14-digit string in the Immo-ID.

It is Immob III. Does that mean that I need to get my SKC code to set it up? Is the SKC code the 7 digit number that was on my key tag when I bought the car?

Nope, 7-digit SKC's were never supplied on key tags, those always had 4-digit SKC's. Remember, the 7-digit SKC is only an encrypted 4-digit SKC.

BTW: Could you please post a complete Auto-Scan?

No, 2003 cars did not come with SKCs on any tags.

Try cold-booting the car. Remove both battery cables from the battery. Short the battery cables together (away from the battery) for aboyt 15 seconds. Reconnect the battery. No guarantees, but I've seen this fix similar problems and it doesn't cost much.

Thats odd that I have a small sticker on the back of my key code tag that has 7 digits. It is 2 numbers over 5 numbers with no letters if that makes a difference.
