Speed from PCM(StockSCC)

SpeedFromPCM

PCM vehicle speed control. 0: Curve/Camera Deceleration + Long, 1: Stock set speed without button spamming, 2: Curve/Camera Decel, 3: Honda/Toyota (Toyota/Lexus use stock set speed; does not switch longitudinal mode)

• Type: Segmented choice
• Default: 2
• Range: 0 ~ 3
• Step: 1
• Menu: Vehicle & Hardware > Vehicle Aux

Behavior

The selected value changes behavior as follows.

• 0 — Curve/Camera Deceleration + Long
• 1 — No Button Spamming (Stock SCC)
• 2 — Curve/Camera Decel
• 3 — Honda/Toyota For Toyota/Lexus, 3 uses stock SET/RES speed as the base control target and stock cluster set speed for display. Mode 1 also uses stock set speed; 0 and 2 retain existing Carrot speed selection. Honda mode 3 is unchanged. This setting does not switch the longitudinal controller or radar availability.

Mode 0 has one exception: on TOYOTA_RAV4_TSS2_2022 with PCM and openpilot direct longitudinal control, stock set-speed changes or disabled-to-enabled cruise transitions observed through valid CAN update the base target. An initially enabled sample only establishes a reference; local button or Bluetooth speed changes take priority in the same cycle, lower lead/curve/map targets remain effective, and no RES/SET CAN transmission is added.

Usage

Change one item at a time only on supported vehicles, then verify steering or stock SCC behavior on the next drive.

Reference

[!CAUTION] A value that does not match the vehicle control configuration can change steering or stock-SCC behavior.
