Please Help no rpm indicator, gear indicator, door indicator
Hi Guys,
I'am new to this forum and I bought an 2008 Yaris sedan Canadian recently and I noticed the RPM Gauge, gear Indicator, Door Indicator, Parking brake warning light don't seem to be working I have read many forums and have tried replacing fuses such as the met,panel1,panel2, gauge, ecu-ig even though these were not blown. I have also tried replacing the Instrument Cluster but that was no help. I also replaced the fuse box and that didn't help either. This car is an auto base model sedan does this car not come with these features or is there something wrong? Any sort of help will be greatly appreciated Thank You |

That's an odd one. One of the fuses you listed would have been my bet.
All of those features should work on your Sedan, so the problem is still likely an electrical one. The first thing I would verify is that the connectors are properly seated. Considering that you have swapped the cluster, that it not likely to be an issue, but make sure that you can see the tips of all of the pins visible on the hole side and make sure that the pin latch is snapped down, so that the connectors go all the way in. From there, the next step would be to check some pin voltages and continuity to ground of the ground pins. Do you have a multimeter?

Hi,
I would also like to mention that when i do connect my elm to the OBD i do get the reading for the rpm's and also the dome light when set to door does turn on when a door is open the problem is the cluster is not displaying it. I really don"t know what to check except for what CTScott mentioned earlier |

OK. You have two connectors - a 24 pin and a 40 pin. When you are looking at the back of the connectors with them plugged in pin 1 is on the upper right.
12----1 24---13 20-------1 40------21 On the 24 pin connector check the following: 1. Voltage on pin 1 (black wire) with key off and on: 2. Voltage on pin 2 (light blue wire): 3. Voltage on pin 14 (green wire) with key on and headlights on: 4. Continuity to ground of pin 24 (brown wire) with key off: On the 40 pin connector check the following: 1. Voltage on pin 16 (green wire) with key on and headlights on: Do the turn signals work on the cluster?

hi i tested the pins today and the readings where as following
24 pin connector pin 1 with the key off 0.001 and with key on 12.4 and start 14.17 pin 2 read 12.9 with key off and 12.4 key on and start 14.2 pin 14 with key on and headlights on was 12.414, with headlights on and car started was 14.2 continuity of ground was good on pin 24 40 pin connector pin 16 when started read 14.2, 12.2 with key on |

Do these voltages sound right?

Those are all fine.
You mentioned a ScanGauge. Have you tried disconnecting it, as the RPM comes to the cluster via CAN bus message? The door open status comes via CAN bus as well on some configurations of the Sedan cluster.

yes that was the elm 327 i only use that to read codes and i disconnect it every time
what can it be if all those voltages are correct? I really have no idea were to go from here |

Do you know how the message goes from can bus to the cluster because I know the can bus is receiving the message

Do you just use your ELM with a smart phone, or have you used it at all with a PC?

That's good. If the CAN voltage measurements check out OK, then I can walk you through sending some commands directly to the cluster ECU.

i checked pin 20 (green) and pin 21 (white) on the small 24 pin wire that plugs into the cluster, is this the connector you were referring to?

Yes. On the right side connector. Those two pins, with the connector plugged in and with the ignition on, should each read about 2.5 Volts to ground.

Hi,
After plugging the connector in pin 20 reads 2.54 and 21 reads 2.6 |
