Voltage supply to TPM ECU is too low.
â–¶ How to fix
Check battery capacity and alternator charging. If the voltage supply in the ECU connector is within voltage limits, from 18 Volts to 32 volt, there is a fault in the ECU. Replace TPM ECU.
What you'll see
TPM system may not set high\ low pressure warnings neither leakage warning.
System reaction
TPM system functionalities may be reduced due to other systems may stop to transmit CAN signals used by TPM ECU.
Diagnostic depth
Detection
The DTC will set during the following conditions: 15 and 30 are On; Supply voltage is lower than 32 Volts.
Possible cause
Supply voltage has been decreased lower than 18 Volts.
