For owners in Thailand dealing with this "hot" issue, the primary advice from community forums like LDV T60 & D-Max Owners

: Professional technicians often use specialized tools like the Autel MaxiSys to attempt a deep reset of the SRS module. Voltage Verification

A: It occurs globally but is more frequent and severe in Thailand due to climate. isuzu isuzu thailand error b101d30 hot

Clear the code. Run the A/C at max for 30 minutes. Restart the engine. If the code returns immediately, the sensor is permanently damaged. If the code stays away, monitor for recurrence.
