Question about 2001 Toyota RAV4

1 Answer

Re wiring Toyota Rav 4 With 1AZ-FSE engine. Attempted theft of ECU resulted in the cutting and removal of all connectors to the ECU, which were cut off and removed from vehicle and are no longer available. Replacements were found which fit ECU but correct connection sequence is required to connect wiring to ECU....A wiring diagram would be great!... Can any one help? Regards Johngee

Thanks for your concern guy's. We did manage to fix the problem....It took us about four days of laborious work....We had to remove the harness covers and work our way backwards and forward, from the management computer, to and from the relevant 'sender unit' coolant temp, air temp, manifold pressure, lumda and oxogen sensor and from the controlled units, ie, ignition system, injection system, cooling fan set up and so on. We managed to identify the connections by following the identification labels printed onto the circuit boards.

We think that Toyota could make life a lot easier, if they used a standard wire colour coding and did not change that colour inside the loom....It is not un-common to see, as an example, a red with white tracer at one end and that may be joined to a blue with red tracer at the other end....If the loom cover is not removed and the cable inspected, you could not guess from what goes in, what will be coming out.

Hope this will be of help to someone somewhere.

Best regards

RAV 4 2004 cruise control not working- checked fuses & brake & clutch switch operation- ok


my guess, NO SCAN TOOL?

you can't fix car with out, a (drum roll) SCAN TOOL

the modern car also cuts cruise for many reasons.

(death) reason and #2, billion dollar class action suits. (read news?)

so they now cut the cruise for lots of engine failures and trans.

no scanning the PCM now, you lose.



2004 RAV 4 no engine stated.

if it has TBW (throttle by wire ) that too, cuts CRUISE big time if iffy

yes,DTCs for TBW or limphome of any kind !!!



what engine, we cant fix engine issues, with out that.

only about 10% here post that. so most answer are wrong.

imagine with body shells missing , see that < what is it,its a drive train. what is yours? engine and trans. what?



causes?

Check engine light on runnning

Scan tool shows, DTC errors. BINGO.

scan tool show stuck on limphome?

Throttle or idle errors of any kind?

there is no cruise module on ours USA>

The PCM mimics that in pure software (fact)

so if the PCM is unhappy, it does in fact cut cruise.



no scan tool makes all this IMPOSSIBLE on all newer cars !!!!



see PCM see throttle motor, bingo its cruise TOO.

I have toyota Gaia wit 1az-fse engine when engine check light comes on it loses accelleration power,so we changed the fuel pressure sensor nothin changed next we changed computer bt after some time th


In stead of changing what is not wrong, save money and time by having the fault codes read and fixing the fault
check engine lights refer to both an engine problem and a transmission problem so what you may have could be in the transmission.

My Rav 4 cuts out when travelling engine light comes on switch off then starts ok Why?


Not enough info yet. Have you tried pulling the codes, that should help give an indication of where the problem is occurring. Take it by an autozone and they can tell you if the ecu has captured any fault codes.

Wiring ecu DIAGRAM 1AZ-FSE


What is a "Help" tester??
Use an OBD2 sacnner and read to DTC?
Why did you unplug or R/R the ECU in the first place.
With just the information you provide your problem might be in the wiringharness or a bad ecu..

1JZ FSE toyota Mark II - the engine can't start; it abruptly cut off. It is able to start when fuel is manually injected into the carburator but cuts off immediately this fuel dries up


sounds like your fuel pump is bad and not supplying fuel can you hear it run when you switch key to on but not turning engine over

If you are looking for a method of preventing the vehicle from being stolen, a better approach is to cut off the ignition supply to the engine management unit or ECU.. Use a circuit diagram of the ECU wiring to determine the ignition feed or feeds and then use a relay to interrupt those feeds. You can switch the relay using a hidden switch or through a vehicle alarm or anti theft device. Disconnecting the starter can be defeated under the hood by shorting the starter solenoid but cutting the power to the ECU cannot easily be bypassed. One word of warning though, DO NOT cut any wires unless you are 100% certain that the wires you are cutting are the correct ones because you can cause the ECU to set fault codes in its memory which can seriously affect the driveability of the vehicle. If you have any doubts, consult a qualified person..

yes sir it is possible you can remove the catalyst do one thing search for good exhaust system repairer or fixer who might had done such thing previously successfully the simple thing is that the catalyst consist of ceramic material inside which look like bee's home nest the only thing you have to do is 1st you have to remove the catalyst cut it by welder then remove the ceramic which is like soil break it completely then after it is completely broken & removed you need to re-fix or weld it again as it was cut to remove the ceramic material it's a typical procedure for better result & hazel free driving do visit your nearest TOYOTA authorised service centre or workshop for more quires do write in to us & problem will be sorted out.

1998 rav 4 ecu pinout location


sorry never done one so i havent a clue,in the good old days the tach connected to the coil wire but now with all this fancy electrics ,Well what happens is they call it vehicle security so they dont have to release the diagrams and this is done to stop people like myself from by passing the immobilisers when we service a vehicle.Because no doubt as you are aware on new cars that if you drop the oil the immobiliser cuts in.Change the battery and the same thing happens.So what happens to keep the dealers in work ,yes you have guessed it no wiring diagrams ,multilayered circuit boards and wires all the same colour to stop people like me from soldering the two outside legs together of a big switching transistor together to make the vehicle general mechanic friendly.Also encrypted software is used to stop the fault codes from being read ,they throw up the wrong code ?? try asking dealer to install then post where he connected too .,best of british with it

Where is the tach wire in 1998 toyota rav 4?


You are not going to find the Tach wire in the engine compartment, because the tach signal comes out of ther vehicle's ECU.

The Tach wire is solid BLACK, located on pin 13 on the ECU.
