L - Model: MR2 1,6 MR2 2,O Year: 1985-00 Engine code: 3s-FE, 3s-GE, 4A-GE System: TCCS TOYOTA Engine management General information Refer to the front of this manual for general test conditions, terminology, detailed descriptions of wiring faults and a general trouble shooter for electrical and mechanical faults. 0 Trouble codes are displayed by the malfunction indicator lamp (MIL). Accessing 4A-GE - without airflow meter Switch ignition ON. Bridge data link connector (DLC) terminals El and TEI (T) a. If no trouble codes are stored, the lamp will flash once every 4,5 seconds O. Individual short flashes display trouble code El. Warning lamp flash duration: 0,5 second El [A]. A 0,5 second pause separates each flash El [B]. A 2,5 second pause separates each trouble code El [C]. For example: Trouble codes 2 and 4 displayed a. Trouble codes are repeated 4,5 seconds after last trouble code El [Dl. Count MIL flashes. Note trouble codes. Compare with trouble code table. Switch ignition OFF. Remove bridge wire. Rectify faults as necessary. OFF
