Toyota Hiace/Great Wall C30/Camry/Corolla Reverse Light Switch 84210-12040 Manual Transmission Standard

Shifting into reverse, if the reverse light doesn’t illuminate, the rear radar has no response, or the rear camera image cannot automatically switch, this usually indicates aging or sticking internal contacts in the reverse light switch, causing signal transmission failures. The switch sits on the manual transmission housing and, when shifted into reverse, completes the circuit to illuminate the reverse light and activate the rear assist system. Compatible models include Toyota Hiace, Great Wall C30, Camry, Corolla, etc. OEM number 84210-12040. Installation requires disconnecting the battery negative first; remove the old switch, check the transmission oil level, and tighten the new switch to the torque specified in the service manual to avoid thread damage.
