Title: CELLULAR COMMUNICATION: SAFETY CONNECT SYSTEM: B157011,B157013; Indicator (Red) Circuit Short to Ground; 2023 - 2024 MY RAV4 RAV4 HV [10/2022 -        ]

DTC

B157011

Indicator (Red) Circuit Short to Ground

DTC

B157013

Indicator (Red) Circuit Open

DESCRIPTION

This DTC is stored when the DCM (telematics transceiver) detects an open or short in the manual (SOS) switch red indicator circuit of the manual (SOS) switch.

The manual (SOS) switch red indicator illuminates for 2 seconds and goes off when the ignition switch is turned to ON. If a malfunction in the safety connect system is detected, the manual (SOS) switch red indicator will illuminate.

However, the manual (SOS) switch red indicator may not illuminate when this DTC is stored.

DTC No.
