If all flicker lengths are the same, then it confirms that all circuits are ok.
1st flicker - revolution sensor circuit
2nd flicker - speed sensor circuit
3rd flicker - throttle sensor circuit
4th flicker - shift solenoid A circuit
5th flicker - shift solenoid B circuit
6th flicker - over run clutch solenoid circuit
7th flicker - lock up solenoid circuit
8th flicker - fluid temp sensor or automatic transmission power circuit is damaged
9th flicker - engine revolution signal circuit

If all flickers are on for a time of 1 second each - battery is low, or wrongly connected, or has been off for a long time.
