I haven’t been able to find anything on the forum so I thought I’d ask if anyone has had this code?

I took my vehicle into Toyota to have them check a very faint popping noise I had when turning left into my driveway. I replaced lower control arms, outer tie rod ends, upper ball joints, sway bar bushings, sway bar links. It’s lifted with a Toytech 3” lift and 155K miles...the lower control arm needed replacing so I went ahead and did some maintenance.

So back to the code...the dealer couldn’t replace the sound and thus told me the hydraulic brake booster pump needed replacing. It went in with no noises and now the abs braking is making noises at 10-15 mph. The service tech said he ran a code scan and it showed code DTC C1452. The vehicle is at the dealer while they work up a best and final price to repair.

Have any of you had experience with this code and if so what was the resolution?

Thanks in advance.

C1452: Code Meaning, Causes, Symptoms, & Tech Notes

Issue resolved...turned out the dealer was trying to sell me something I didn’t need. The dealer said all front end components were good and torqued to the appropriate specs. I took the vehicle, disabled traction control and re-engaged it then shifted into and out of 4 low and surprise no more electrical noise. Thanks for the comments.

I'm just going to copy/paste your complaint. Did you ever figure out the popping noise when turning left? mine started after Firestone did an alignment after I installed "take off" suspension.

He had it stuck in traction control on dry pavement.

Huh?
