Mazda cx 30 shuts off after pressing the brake pedal

Fri, 03 Jul 2026 20:07:31 +0000

I recently purchased the THAR-ONE-MAZ5 with the EVO-ONE remote starter and immobilizer bypass module for my 2023 Mazda CX-30. I installed everything following Manual #99841, but I’m experiencing an issue.

Problem 1: Vehicle Shuts Down After Takeover

After remote-starting the vehicle using my OEM key, I follow the takeover procedure (Page 11 of Manual #99841). However, as soon as I press the brake pedal, the engine shuts off.

Problem 2: A/C & Accessories Not Working Properly

Additionally, most accessories (including A/C) do not turn on during remote start. Even if I manually activate the A/C after remote starting, I can hear the compressor running, but the blower fan does not work nor the A/C interface screen.

Takeover Issue with 2021 Mazda CX-30

Fri, 04 Nov 2022 23:53:50 +0000

Hello,

I am having an issue with Takeover with my 2021 Mazda CX-30 GT Turbo (Canada) and EVO-One with T-Harness.

If I remote start the vehicle using either the OEM keyfob (lock-unlock-lock) or with one of my two-way remotes via RF Kit, I can't successfully complete a takeover.

I unlock via door handle (advanced keyless entry), sit down, and hit the push button ignition twice, but receive a notification via dash of a Keyless Ignition System issue, and to have the vehicle checked.

Any ideas? Running the latest firmware for both Bypass and RS as of today (Nov 4, 2022).
