Instrument cluster light

[Pitt Yaris]

i have stock everything, and my light came on about 2-4 weeks after i bought it *new* i checked the tire pressure, and it's fine. anything else i can do? could take it to the dealer, but would rather not deal with the hassle.

You can read the error code from the "blinks" of the TPWS light. This will tell you what the TPWS thinks is wrong.

To do so:

1. Turn the iginition off

2. Connect the CG (pin 4) and TC (pin 13) pins together on the DLC3 connector (also known as the OBDII connector). You can do so with a small clip lead.



3. Turn the ignition on

4. TPWS light will light steady for three seconds

5. TPWS light will flash in a pattern indicating the stored DTCs (trouble codes). The pattern will require you to count the flashes and discern the delays between.

For example, if DTCs 13 and 23 are stored you will see:

0.5 second flash
1.5 seconds off (1)

0.5 second flash
0.5 second flash
0.5 second flash (3)

2.5 seconds off (gap between stored codes)

0.5 second flash
0.5 second flash (2)
1.5 seconds off

0.5 second flash
0.5 second flash
0.5 second flash (3)

4.5 seconds off (gap between repeating)

Then, it will start again and will repeat until you kill the iginition and remove the jumper.





What the codes mean:

11, 12, 13 or 14 (Tire pressure low on one of the 4 tires)

21, 22 ,23 or 24 (No signal from one of the 4 sensors)

41, 42, 43, or 44 (Transmitter ID error on one of the 4 sensors)

65, 66 ,67, or 68 (Abnormal temperature inside one of the 4 tires)

71 (Transmitter ID not registered)

73 (Vehicle speed or Engine Speed Signal Malfunction)

76 (Malfunction in TPWS ECU internal cuircuit)

91 (Vehicle Speed Sensor Error)

94 (Engine Speed Sensor Error)

Hi, Is there a master list posted anywhere that has all of the codes?

That list is all of the codes. Because the Yaris does not register tires to specific corners, the 4 codes that all mean the same thing are due to the fact that it can be any one of the 4.

Oh, I don't mean just for tires, I mean everything. Or is there something to xref codes read via a jumper to the P type codes?

I jumpered my connector and I "think" it is giving me 34 and 39 (which may be meaningless because I initially had the jumper position reversed which reported nothing but a continuously flashing ABS light. THX!

There isn't a single list, but there are threads on here for TPMS, ABS and SRS, all of which have jumper readable codes.
