The blue temp light indicates that the engine is cold and has not yet come up to optimal running temperature. When the car shut off, were there any warning lights on? It could have overheated, the red temp light would have been on. Is the check engine light on at all?

What is the blue light


if the car is a vw beetle the blue light is the coolant level. it's probably the same with most cars as well. check the fluid levels.

Check ALL of your fuses. The flat fuses, the square block fuses under the hood. The alternator block fuse is most likely the one that is blown and causing the problem. Some Mitsubishi cars have the alternator fuse built into the positive battery clamp. It is easy to short the block fuses and most people and some mechanics do not even think to check them. That is why you always unhook the negative battery cable when working on the car. With any luck a $2 fuse will get you started again.Also if your battery is not putting out 12 volts , that can cause all kinds of issues around the car. Go to the auto store and purchase an squeeze ball/eye dropper style battery tester with the floating balls and test the cells of your battery to see if they are all good.

The Drive light flashes and the car loses power and sometimes won't start.


It is either your Vehicle Speed Sensor (easy to change) or your Automatic Transmission Computer (capacitors burn out on these boards, there is a fix for this too, the picture is at the bottom of this page). You need to diagnose by removing the lower right plastic kick panel on the passenger side. There you will find a blue plug. With the car OFF stick a paper clip, wire or stuff the plug with foil to make electrical connection so that the two terminals are touching. Then, turn the ignition to ON (not enough to start it though, just power it up). When you do this, count the blinks in the "D Light" or count your blinking Check Engine Light. Both are different but can refer to different things wrong with your car. A long blink is the first number and the short blinks that follow are the second number.
So imagine this as being 14 : ___ _ _ _ _

Below is a decoding chart:

The first section will be the check engine light codes, the next one is the Transmission Control Unit Codes read from the D Light;

1 O2A - Oxygen sensor #1
2 O2B - Oxygen sensor #2
3 MAP - manifold absolute pressure sensor
4 CKP - crank position sensor
5 MAP - manifold absolute pressure sensor
6 ECT - water temperature sensor
7 TPS - throttle position sensor
8 TDC - top dead centre sensor
9 CYP - cylinder sensor
10 IAT - intake air temperature sensor
12 EGR - exhaust gas recirculation lift valve
13 BARO - atmospheric pressure sensor
14 IAC (EACV) - idle air control valve
15 Ignition output signal
16 Fuel injectors
17 VSS - speed sensor
19 Automatic transmission lockup control valve
20 Electrical load detector
21 VTEC spool solenoid valve
22 VTEC pressure valve
23 Knock sensor
30 Automatic transmission A signal
31 Automatic transmission B signal
36 traction control found on JDM ecu's
41 Primary oxygen sensor heater
43 Fuel supply system
45 Fuel system too rich or lean
48 LAF - lean air fuel sensor
54 CKF - crank fluctuation sensor
58 TDC sensor #2
61 Primary oxygen sensor
63 Secondary oxygen sensor
65 Secondary oxygen sensor heater
71 random misfire cylinder 1
72 random misfire cylinder 2
73 random misfire cylinder 3
74 random misfire cylinder 4
80 Exhaust Gas Recirculation insufficient flow detected
86 ECT Sensor (Engine Coolant Temperature) circuit range / performance problem
90 Evaporative Emission Control System leak detected in the fuel tank area
91 Fuel Tank Pressure Sensor low input
92 Evaporative Emission Control System insufficient purge flow

TCU Codes:

Blue light started flashing what is wrong


Hi, has the weather just turned colder? The Beetle has a blue warning light to tell you that the engine temperature is low. Meaning drive the car at lower speeds/revs until it's warmed up and the light go's out. Hope that helps, Matt.

Blue light stays on in my 2000 beetle sometimes flashes


Not certain, but you may be referring to the blue light that indicates when the water temperature in the cooling system is "cold". It's typically blue when the car first starts, then changes color when the water temperature rises. If the light remains blue the water temperature isn't heating up, and you may want to have the cooling system flushed and checked. Depending upon the cars mileage, it may be time to flush the cooling system anyway.

03 suzuki aerio automatic transmition won t shift into overdrive


You have two temperature lights that come on when you start the car, one red and one blue. After the car is started the red light goes out and the blue one stays on. According to the manual, (and from my personal experience with my '03 SX), the car needs to warm up to a proper operational temperature. This temperature is reached once the blue temperature light turns off, (or within seconds afterwards). If you don't allow your car to warm up you will notice hard or long shifting, rough idle, and poor engine performance. Never drive your car if the light displays a constant red temperature light.
If this solution does not work see a Transmission expert of take it to your local Suzuki Dealer.

Check your coolant level first then start having sensors checked. Could be a bad sensor or wiring issue.
