Suzuki coolant DTC
Some 2007-2008 Suzuki XL7 vehicles may exhibit a check engine light with DTC P0128 (engine coolant temperature (ECT) below thermostat regulating temperature) stored.
The cause may be mis-calibration for vehicles with rear HVAC. Heat-up time is exceeded due to extra coolant capacity of rear HVAC-equipped vehicles.
Do not replace the engine control module (ECM) or thermostat. Follow the service manual procedure to reprogram the ECM with the latest software. Be sure to click “Clear DTCs” after reprogramming.
