mayor2013:
From your long list and questions. Am sure some road side electrician has done some wonders on your car before you came up here with your car story.

I still don't get what you mean by diagnostic tool not reading transmission information. Is it dat d tool is not conecting I, e you getting a communication error. Note : not all scanners out there are capable of reading transmission fault code.

[/color]They have tried many scanners, they can't read my transmission information sir. It's like there is a disconnection to the brain box, or something.



If your headlight keeps burning out within a month, am looking at a situation where your are using substandard bulbs or you are having an incorrect charging system (over charging). Ask your electrician to check your charging system. Could be more than the expected

[color=#990000]Will talk to my mechanic again. We have used both Brand new and Tokunbo. I don't cut corners when it comes to my gadgets/electronics.


For your dashboard light going off. Before this happens do you notice cases where by the dashboard lights suddenly go dim mostly @ night?

[/color]Nope. No warning signs, just burns. Although at times, the dim burns out before the full light follows suite a few days later.

As for the sound you hear while on motion. Tell your mechanic to check your hub

[color=#990000]Yes, he said so. But I also suspect my exhaust. Because I hear like sound too when warming the car in the morning.

Check your suspension.

[/color]Ok. Will talk to my mech.

Oil stain drop tell mechanic to trace that

These issues are some reason why one could just become depressed. I Feel your pain bro

1 your headlamp burning off constantly, have you gone thru your owner's manual to see the specified/recommended bulb type? Do that and make a change to the genuine type. Also, it could be that your electrical fixtures for your headlamp is breached, short circuited, loose earth wire or bypassed and a relay installed. Check and revert to factory settings.

[/color]Ok Sir. I think I will download a comprehensive manual and study it.[color=#990000]

2. Your tyre pressure. What is the Pressure in Each tyre? Once you've noted the Pressure level on each tyre, go to the driver's side B pillar and look at the area under the lock/hook mechanism to determine the Cold Tyre Pressure rating indicated (my own cars recommends 30Psi for all tyres) next, check the tyre specs on that label near the lock/hook mechanism in the B pillar, you'll see the Tyre type specified for your car. Take note of the tyre spec and compare with the new tyres you purchase for consistency or inconsistency. Let's start from the small bit before progressing to the greater deals.

[/color] Doing that right now. Will get back to you.[color=#990000]

3. As for your Dashboard lights keep going off. The hazard, gear, ac, radio indicators all keep
going off and on till you tap on the dashboard, It seem as if wires have been severed, rusted, breaching, short-circuited, or earth wire is loose or loose terminal point. Check and trace your harness to discover the culprit.

[/color]By harness, do you mean the board/circuitry? Will talk to my mech.[color=#990000]

4. I don't know of brass type or any type brake pads, replace your brakepads with genuine OEM brand meant for Toyota Rav4 2002 model.

[/color]Where do I get that? I live in Lagos.[color=#990000]

5. The issue of hubs, check the hubs for grease, worn out ball bearings and joints, etc and replace if worn out.

[/color]Does this mean I don't have to change the whole Hub?[color=#990000]

6. As for the engine oil, and filter, I replace my filters anytime I change my oil. I don't go about using old filters with new oil.

Hello All,
I want your opinions and advice on how to go about the following issues on my RAV4 Toyota 2002 Model

1. Diagnostic tools cannot read Transmission data. This means whenever i scan for issues, the machines cannot read my tranmission. Could this be a gear problem or a brain box issue?

2. My full and head lights keep burning out within a month. What could be the cause? I have spent good money buying new bulbs to no avail.

3. My Dashboard lights keep going off. The hazard, gear, ac, radio indicators all keep going off and on. I do tap on the dashboard to bring them on. As if there is a disconnect somewhere.

4. My car uses more fuel when I'm on the express than when I'm within town. for example, when i drive 2 hours to Ibadan, the car guzzles more fuel than when I spend the same 2 hours in traffic within Lagos. Is that normal?

5. I hear some serious humming noise whenever I'm speeding on the expressway. My mechanic says its the HUB that needs change, but I also suspect my exhaust. What do you think?

6. I changed my four tyres last month, and since then its as if my shock absorbers are no longer working. Every time I hit a gallop, the effect is amplified. Could it be the tyre pressure or something is missing?

7. This morning, I noticed some oil stain/drops under my engine where I parked my car at the office. What can that mean.

8. I last serviced my car 60 days ago. Do I need to change oil filter when servicing next? How frequently should i service the engine?

9. I just changed my Brake pads. My mechanic says the BRASS type is best for my car. What do you think?

Thanks in advance for your helpful tips.

GAZZUZZ:



what works for me

1.from experience only high end diagnostic tools will read out data from your vehicle, find someone who uses launch or equipment
specifically designed to diagnose Toyota to solve this problem.

2.Buy tokumbor its 400 a piece lasts for years.

3.you have a partial contact, get a smart sparky to find it.

4. If you solve problem 1, you will understand problem 4.

5.Rule out the Exhaust by going under the car and looking for dark patches along the exhaust this will indicate a leak, or go under have
someone start engine and listen for leaks.

OR you bought tires meant for OFF road they are very noisy.


6. you have excessive air pressure in your tyres

7.For this one roll up your sleeves go under the car if you don't know the name take a picture we will tell you what is leaking and what to do
about it.
8.what does your car manual say?

9. so much rubbish in the market, i really cant tell you what to buy, but enter any Toyota dealership, their pads are expensive but will last way longer than the after market type, while saving your rotors from damage.

good luck.

eveneky:
