Fail-Safe Chart [12/2017 - ]
- WIPER MOTOR PROTECTION FUNCTION
- If the wiper system is malfunctioning, the windshield wiper motor assembly performs a fail-safe function to control the system.
Item Fail-Safe Function Conditions to Return to Normal Condition Overheat protection Decreases wiper operating speed in order to protect the windshield wiper motor assembly if the windshield wiper motor assembly temperature becomes excessively high. - Restricted to LO wiper speed: 95°C (203°F) or higher
- Restricted to INT (LO wiper speed): 100°C (212°F) or higher
- Operation prohibited: 105°C (221°F) or higher
The windshield wiper motor assembly returns to normal. Snow protection Reverses the direction of the wipers and decreases their operating range when an excessive load, due to snow, etc., is detected near the extremities of the wiper operating range.
In this case, operation is stopped at the lower reverse position for a certain period of time to prevent the motor from overheating.Foreign matter, such as snow, is removed and the front wiper operating range returns to normal. Excessive load protection Operates the wipers 4 more times before stopping the wipers when excessive loads to the motor are detected in the center area of the windshield glass during motor operation Returns the windshield wiper switch assembly back to normal via switch operation
- If the wiper system is malfunctioning, the windshield wiper motor assembly performs a fail-safe function to control the system.
- RAIN SENSOR FAIL-SAFE FUNCTION
- The windshield wiper switch assembly performs a fail-safe function when the wiper system cannot properly receive the necessary signals for wiper system control or a wiper system component is malfunctioning.
Item Fail-safe Function Conditions to Return to Normal Condition Rain sensor LIN communication error Continues control according to the conditions detected before the malfunction. LIN communication returns to normal. Rain sensor voltage is too low Rain sensor voltage returns to normal. Abnormal rain sensor signal Performs intermittent operation according to the position of the auto sensitivity adjustment switch. The rain sensor returns to normal. The rain sensor temperature is too high (90°C [194°F] or higher). Stops the wiper operation. The rain sensor temperature is too low (-15°C [5°F] or lower).
- The windshield wiper switch assembly performs a fail-safe function when the wiper system cannot properly receive the necessary signals for wiper system control or a wiper system component is malfunctioning.
