Code 6 means engine coolant temperature ECT to erase it make sure ignition is off remove fuse F11 ( 10 amp) for 10 seconds and refit fuse Before you do these things make sure your engine is not over heating because you could be doing your engine damage If you ignore this code

ECM requires both crank sensor signal and cam sensor signal to fire the coils. Check for spark at the plugs first. Check the plug wires, then the coils. Only if you have no spark at any coil would I suspect the ignition module, and even then only if you have a good crank and cam signal. Do you have any codes stored in the ECM? They could help pinpoint the problem.
Error Code: DTC P1300 Description: Igniter Circuit Malfunction Solution:
To repair the code please do the following:
1. Check spark plugs.
2. Check for open and short in harness and connector in IGF (Ignition Confirmation) signal circuit between ECM and igniter.
3. Disconnect igniter connector and check voltage between terminal IGF of ECM connector and body ground.
4. Check for open and short in harness and connector in IGT1 - 3 signal circuit between ECM and igniter.
5. Check voltage between terminals IGT1 - 3 of ECM connector and body ground.
6. Disconnect igniter connector and check voltage between terminals IGT1 - 3 of ECM connector and body ground.
8. Check for open and short in harness and connector between ignition switch and ignition coil, ignition coil and igniter.
9. Check and replace ignition coils with a good known one.
10. Check and replace ECM with good a known one .
Hope that works.

For 83-86 Camry, 87 corolla, 84-87 pickups and 4-runner: Code 12 = knock sensor or circuit (distributor or circuit on Cressida, Supra, and Celica 3S-GE)
87-90 Camry, all other models 88-90: Code 12 = Rpm signal/no NE or G signal to ECU within several seconds after engine is cranked.
All models from 1991 on: Code 12 = Rpm signal No "Ne" signal to the ECM within several seconds after the engine is cranked. No "G" signal to the ECM two times in Succession when engine speed is between 500 rpm and 4000 rpm.
There are a couple of possibilities. When you start up the truck there are 2 computers that control the engine. The ignition module and the ECM. After a number of seconds (20?) the ECM shoots a 5 volt signal to the Ignition module and tells it that it is taking over. Whether the two parts communicate, if a signal is sent or not, or a signal is not returned is why the engine is shutting down.
You may get a code on a scanner or you may need a Dealerships Master Analyzer to determine if it is a wire or component.
Second, there are 16 million recalls for Ford and Lincolns. Once the cruise controls were fitted with extra fuses in the first recall, problems with wiring in transmissions and brake systems and dash code indicators appeared. Run your VIN# to check for a covered repair.
Thanks for using Fixya, would like to know the end result of your problem so we can pinpoint this for others.
Do your high beams work? The problem could be your turn signal/high beam switch. If the lights come on when you use the high beams replace this switch. It is available at most autoparts stores. Not a diffucult repair probably under two hours.
