I read DTC in Camry 1998 (JT153XV2000040..., LHD), Avalon (MCX10-AEPGK, RHD), and in other Toyota vehicle according to this description! In Chaser TRD (Toyota Racing Developmed) with 1JZ-GTE, JZX100-00709.. I read codes with connect pins Tc and E1 in DLC No.2.
Besides, I read DTC in Avalon on DLC No.3 with LED-indicator (duality for lamp in instrumental panel) for AirBag, TRC, ABS system and read DTC with short pins in DLC No.1. and DLC No.2.
In Toyota Avensis (SB153ABN00E..., make in Great Britain '98, fuel system BOSCH) this procedure is bad...

Read the DTC from CE (MIL) lamp on the combination meter. Let me know codes. I will make conformity (correspondence) MIL-codes to SAE or to Manufacturer codes and send to you description of the diagnostic procedures and other information..
