Reading Diagnostic Codes on OBD1 Toyotas
Vložit

- 1980s Ecu controlled Toyotas had a built in diagnostic codes for the engine as well as the auto gearbox. To activate the system, you need to short Te1 with E1, then get in the car , insert the key, then turn to the ON position. Do not start the engine. Also make sure your AC and radio is turned off. Your OD lights and Check Engine Light should blink. If both blinks continuously that means there are no error codes recorded. If there are error codes , either the OD or the CEL will blink with pauses in between. if the OD blinks with pause in between, the code is Auto GB related. If the CEL blinks with pauses in between, there are error(s) with the engine.
If say, the OD light blinks 4 times , pauses then blinks 2 times, that is error code 42(speed sensor error). If there are more codes, there will be a long pause in between. The codes will repeat and cycle through repeatedly until you turn the key to OFF. Take note of the codes and check it against your model's TSRM.
To clear the codes for the auto GB, pull the DOME fuse for 10 mins. To clear codes for the engine, pull the EFI fuse for 10 mins.
Hello! thank you for the information video! I checked mine soarer and I have an error code in AT transmition...62. Do you know what it means?
Yours the 2nd gen or 3rd gen soarer ? I dont find error code 62 on us supra. I will try search jdm documents
@@toyotadiy1497 1988 So its a second gen. I think its a 1 selenoid error.
@@Tom-ki yes its solenoid no1
Helo,I hav a 1998 rav 4, bit old,I changed the HT cables n it won't start,replaced the old one it won't start still
If that is the case, your igniter should be the culprit. you sure your RAV4 does not use coil on plug ?
try to see this video czcams.com/video/UBFAhK8qdZU/video.html
@@toyotadiy1497 I checked spark,it has spark, fuel is OK...its the type that has two independent coils,one coil serves cylinder 1& 4 n the other coil serves 2& 3....history of The car.. It used to go off went joining the road at T junctions ( almost hard a tipper truck ram into me once, so I just raised the idling n its crazy high) the temperature sensor looks like it was onced worked on,insulation tape on the wires,...have tried to pull codes its does not give any...I now walk to work. ( 7 km distance) also of late fuel consumption has gone up, with cylinder 3 spark plug n 1 not firing properly.. Bluck carbon on spark plugs
@@luckymutibo9848 then check the crank position sensor. If the ecu does not receive a position signal the ecu will stop spark. I know you have spark now, but if your engine shuts off suddenly it could be missing this signal intermittently.
@@toyotadiy1497 hey,thanks for the info...I removed the ETC sensor,it was full of scales, cleaned it with a sand paper m it cranked...but I have to get a new one, also the fan sensor needs replaced... I hav also noticed after it cranked,idling has gone high...
