TCU won't give me error codes.

[nextse7en]

I've got 16 blinks after a new 4.44 install. I've followed both procedures to a T in order to pull whatever code is stored. neither has resulted in any success, the power light simply remains solid.

Is there another way to pull tcu codes?


Thanks.

This one...

1. Warm up engine by driving at speeds greater than 12mph.
2. Stop vehicle and turn ignition switch OFF.
3. Turn ignition switch ON and make sure POWER indicator lamp comes on.
4. Turn ignition switch OFF.
5. Move selector lever to D and turn manual switch ON.
6. Turn ignition switch ON.
7. Move selector lever to "3" and turn manual switch OFF.
8. Move selector level to "2" and turn manual switch ON.
9. Move selector lever to "1" and turn manual switch OFF.
10. Partially depress accelerator pedal (to turn idle switch off).
11. Check code as displayed on POWER light. Blinking once every 1/4sec is normal.

Neither one works.

Is the idle control switch tied to the TPS?
