The TPMS Module sets DTC C1660 when it does not receive a valid signal from the TPMS Sensor.
Item | Detecting Condition | Possible cause |
DTC Strategy |
•
Monitoring RF signals | 1. Damaged TPMS Module(RF receiver circuit) 2. TPMS sensor which is not fitted in the vehicle specifications |
Enable Conditions |
•
RF circuit failure in the receiver
•
EEPROM failure in the receiver
•
MCU failure in the receiver | |
Threshold value |
•
No valid RF data is received from any sensor for consecutive 9min while VS is higher than 15MPH(25KPH) (RF circuit failure)
•
Communication failure or data loss is detected (EEPROM failure)
•
Internal micro controller failure is detected | |
Diagnostic Time |
•
9minutes for RF circuit failure AND At the time of failure detection (EEPROM or MCU internal failure) | |
Lamp |
•
Lamp on |
