Subaru Legacy RHD a '01 (TZ1A4Z), A/T

 

 

Engine:           EJ25 2,5 L / 4 cyl / Gas, Fuel: Fuel Injection, Mileage: 93519 km, Frame: BH9 - 053508

Symptoms:     Continuously flashing lampe "POWER" on Instrumental Panel (after Engine is ON). In Memory ECM and TCM no codes were stored during this episode (Check Engine Lamp is OFF if Engine ON).

A/T Mode Selector POWER/HOLD Ind. "POWER" (on Insr. Panel)

I don't know reasons this situation. What to do? What to check up?Any help would be much appreciated.

Cortesy by Alexander (aka indy) I know:"... When any on-board diagnostics item is malfunctioning, the display on the POWER indicator light blinks from the time the malfunction is detected after starting the engine until the ignition switch is turned OFF. The malfunctioning part or unit can be determined by a DTC during on-board diagnostics operation. Problems which occurred previously can also be identified through the memory function...".

I will read* Diagnostic Trouble Codes (without Subaru Select Monitor) and fix problems.

*The POWER indicator light flashes the code corresponding to the faulty part. The long segment (1.2 sec on) indicates a “ten”, and the short segment (0.2 sec on) signifies a “one”.
