17 flashes of OD Off light!

[SaKaNa]

Finally caught it, it seems to flash 17 times... any ideas?

i think that when the OD light flashes, it has something to do with the transmission. a self diagnostics test can be done w/o an obdii reader which is transmission specific. if you have the FSM, it's on page 29 of the AT section.

 

if you don't, here are the steps:

 

1. turn key to "on"

2. move shift lever to "D"

3. turn key to "off"

4. set overdrive button to "off"

6. turn key to "on"

7. wait 2 seconds

8. move shift lever to 2nd gear

9. set overdrive to "on"

10. move shift lever to 1st gear

11. set overdrive to "off"

12. press gas pedal to the floor and then release it

13. look at your OD light...there should be 1 long, then 10 flashes:

 

if all 10 of them are short, then there is no malfunction in the AT

 

if all are not the same, remember which of the 10 flashes are longer.

 

 

1st light is long: revolution sensor circuit

2nd light is long: speed sensor circuit

3rd light is long: throttle position sensor circuit

4th light is long: shift solenoid valve A circuit

5th light is long: shift solenoid valve B circuit

6th light is long: overrun clutch solenoid valve circuit

7th light is long: torque converter clutch solenoid valve circuit

8th light is long: a/t fluid temperature sensor

9th light is long: engine speed signal circuit

10th light is long: line pressure solenoid valve circuit

 

so it pretty much tells you which a/t circuit is shorted or disconnected.

 

this could be something totally irrelevant, but at least you can give it a shot =P

No tranny issues, its something else... mechanics computer said tranny has no error codes, and speed sensor is reading the speed... but I've never managed to catch the OD lights number of flashes, i THINK it was 17.

reset the computers and see what happens. i think it might be the speed sensor just double check it to be sure. it is something to do with the trans. the o/d light is kinda like the check engine light for the trans.

My mechanic cleared *all* error codes in everything possible, and it came back within a couple days. But his computer when we drove around, was showing the MPH and RPMs with no problems.

The number of flashes on startup doesn't matter, it flashes for approximately 8 seconds just to let you know you're in failsafe mode. It's not designed to indicate what the problem is.
