A Tribute to technology
Some 2010 Mazda Tribute vehicles may exhibit a MIL on with DTC P0128 (coolant temp below thermostat regulating temperature). This concern may be more pronounced in cold ambient temperatures when the engine is first started after a cold soak, and then driven under light load/low speed conditions with the climate control blower motor setting on high. No drivability issues may be present.
1. Reboot the IDS to clear memory before reprogramming.
2. Using IDS 67.04 or later software, reprogram the PCM to the latest calibration by following the “Module Reprogramming” procedure.
- Always update the IDS tool first, then follow on-screen instructions to download the needed calibration file for PCM reprogramming.
- It is not necessary to remove any fuses or relays during PCM reprogramming when the IDS screen prompts you to do so. You may accidentally stop power to one of the PCM terminals and cause the PCM to be blanked, or you may receive error messages during the procedure.
- IDS shows the calibration part numbers after reprogramming the PCM.
- A battery charge should be connected to the vehicle battery when performing the procedure, to a maximum charge of no more than 20 amps. Excessive amps could damage the VCM.
- After performing the PCM reprogramming procedure, it is no longer necessary to road test the vehicle to “relearn” KAM (keep alive memory).
