Toyota Corolla Cross: Operation Check

OPERATION CHECK

CHECK SRS WARNING LIGHT

(a) Primary check

(1) Turn the ignition switch to ON and check that the SRS warning light turns on.

(2) Turn the ignition switch off. Wait for at least 2 seconds, then turn the ignition switch to ON. The SRS warning light comes on for approximately 6 seconds and diagnosis of the airbag system is performed.

HINT:

• If the SRS warning light remains on for approximately 6 seconds or more after the ignition switch has been turned to ON, there may be a malfunction in the SRS airbag system.
• If the SRS warning light occasionally turns on approximately 6 seconds or more after the ignition switch has been turned to ON, there may be a short to +B, short to ground or an open in the SRS warning light circuit.
• If the SRS warning light illuminates after turning the ignition switch off or to ACC, there may be a malfunction in the power source circuit or combination meter assembly.
• The SRS warning light turns off, and then turns on. This blinking pattern indicates a power source voltage drop. The SRS warning light turns off 6 to 10 seconds after the power source voltage returns to normal.

FUNCTION OF PASSENGER AIRBAG ON/OFF INDICATOR

(a) Initial check

(1) Turn the ignition switch to ON.

(2) The passenger airbag ON/OFF indicator comes on for approximately 4 seconds, then turns off for approximately 2 seconds.

(3) Approximately 6 seconds after the ignition switch is turned to ON, the passenger airbag ON/OFF indicator will indicate ON/OFF depending on the following conditions.

• *1: The system judges a person of average adult weight or more as an adult. If a smaller adult sits in the front passenger seat, the system may not recognize them as an adult depending on their physique and posture.
• *2: The system may not recognize a child or a child in a child restraint system as a child depending on factors such as the positioning of the child restraint system or the child's physique or posture.

HINT:

• The passenger airbag ON/OFF indicator illuminates based on the following timing chart in order to check the indicator light circuit.
• When the occupant classification system has a malfunction, both the SRS warning light and passenger airbag ON/OFF indicator ("OFF") come on. In this case, check for airbag system DTCs first.
