Christmas tree lights on instrument cluster

Trying to figure this out. 2006 toyota tacoma 296k miles, original engine was replaced due to a blown head gasket 1500 miles ago. P0500 was intermittent prior to swap but the abs light and the brake light is new. Cruise control wasn't even lighting up for years, I've owned this truck for 6 years now. Cruise control just recently started working intermittent as well. Cruise light is coming on but it's not engaging each time. C1239,C1240,C0215 currently along with the p0500 code. I replaced the engine with a 07 FJ engine with 78k miles on it. None of these codes are associated with the swap im pretty sure? Im at my wits end, im disabled and it took everything I had to get the engine and swapped. Is it possible that it's the instrument cluster itself? I know I've gotten under the back near rear left tire and I see the WSS wiring was spliced at some point. Questions are
1. Could it be possible the instrument cluster is responsible for the p0500?
2. Would the ABS codes be triggered by the IC?
3. Any direction someone could please point me, where I could study up more so I can at least cut out the expense of troubleshooting Would be awesome and appreciated!

Thanks ☺️ Will aka 2006 tacotacoburrito

 

Your speedometer works so odds are the P0500 is the cluster.
We have a working bypass/workaround for it.

The ABS light is a separate issue, the C1239 and C0215 are for the Left Rear Speed Sensor. The C1240 doesn't exist for 06 so either you read it wrong or something.

 

Thanks! I looked at the wiring for rear wheel speed sensors and found an old repair and it was broken again so I ordered another one. Both rear sensors have a separate connector that comes into one connector that ties into the wiring from everything else back there. Hopefully this takes care of the C0215 and the abs light goes off, maybe the brake light too? But im also looking at the vss p0500 work around you posted too. My tacoma is a 4.0 automatic so im guessing from that thread, that the vss signal is coming from the rear wheel sensors so it may clear up the p0500 code? The new harness will be here Thursday and im going to put it on ASAP. Thank you so much for your response sir and helpful suggestions/ linked threads. Appreciate it

 

Yea that seems to be a relatively common issue for the wires to break/corrode there at Connector S22, that should fix the C0215 and C1239 codes.

Possibly but I doubt it, it will use one or both rear sensors for vehicle speed and your speedometer looks to be working so it's getting a vehicle speed signal to the Meter.

There's essentially 3 ways to fix the P0500 when the Combination Meter is at fault:

Replace the Combination Meter/send it to be repaired.
Take the Combination Meter apart and try to fix it yourself.
Cut the SPD wire at C9 Pin 19 (Violet/White) and tie it to C9 Pin 6 (Red/Yellow) at the Combination Meter connector.

 

My speedometer is off by around 7 mph. It may be because of the 35s but the 35s i had on before didn't change anything on the speed so im not sure. I was an electrician but electronics aren't quite the same I've removed the instrument cluster and cleaned the connectors thoroughly but that's all I did to it. My son has a 2012 and a good friend has an 06 just like I do, they both have told me I could take theirs out and swap them to see if mine is in fact bad. Does that sound like a good way to solve the question of whether that's the issue or not? If I understand correctly, the wire splicing from the pins on the cluster wiring will fix the issue either way? As far as the p0500? I can't thank you enough, I've been seeing your name/profile over and over again in my searches trying to educate myself on several issues and im very grateful that you are helping me. You seem very knowledgeable about these trucks, i know that I love my tacoma and want to keep it and enjoy it for the foreseeable future so ill be going through these posts as I come across other things. As of now, the only other thing im dealing with is the drivers side door lock stopped working with the key fob, it's weird because the rest of them are fine. I had issues with the windows getting stuck up or down and it turned out to be greenish looking stuff in the connectors, little electronics cleaner and they work great now. This truck spent the majority of it's life in Texas so that really doesn't make sense to me but that's my luck lol.

 

Could be because only one rear speed sensor is working.

The `12 won't work, they are on CAN. The 06 would work as long as it's the same engine and trans.

That's probably the easiest fix if you don't wana mess with taking it apart or sending it off.

Well one side of the driver's door lock actuator is on a separate circuit but I'd stick a test light across the control wires (Pin 1 (Blue/Black) & Pin 4 (Blue/Red)) and see if it lights when the locks are actuated but the actuator doesn't move.

 

I'll take door apart today and test that. Thanks again for solid advice. So there's a connector at the lock actuator, pin 1 and pin 4 should light up when actuated? Got it! Thanks ☺️!

 

You may have to backprobe it with some needls or T-pins, I don't know that the locks will work with it unplugged due to the detection switches it has built in.

 

Couldn't find my multi meter so I just took the door apart and cleaned the connections and noticed they were a little corroded but not too bad. It's been gotten into before because there's tape on the plastic and it is obvious someone has dealt with the actuator before. I've seen a video somewhere that had a replacement for the motor in the actuator vs replacement. Any input on that? The actuators aren't very expensive but if it's just the motor then that could keep it going idk. Seems like an hour or 2 process to replace it once the door panel is off.

 

I can't comment on replacing it, I've never changed a door latch or actuator on any Toyota.
I may know quite a bit about them but most of it is from hanging out here, studying service info & wiring diagrams, and my own experiments/reverse engineering. Toyota's just don't come in the shop very often for anything more than basic maintenance, light repairs, and A/C so I don't get alot of hands on experience with them.

I will say this, test the door latch and all the functions to make sure it works and will unlatch before you close the door after doing anything with the latch system. Once it's closed and won't unlatch it's a royal PITA to get in there to do anything with it.
