id0402b2906900

DTC

C1031:54

Tire pressure monitoring system (TPMS) system

DETECTION CONDITION

•  Detects that tire such as temporary spare tire with outer diameter of considerable difference is installed

•  There is a large fluctuation in steering angle and acceleration/deceleration speed repeatedly over short intervals.

FAIL-SAFE FUNCTION

•  Tire pressure monitoring system warning light illuminates after flashes.

•  Inhibits the TPMS control.

POSSIBLE CAUSE

•  Diameter of currently installed tires differs from Mazda recommended tires

•  There is a large fluctuation in steering angle and acceleration/deceleration speed repeatedly over short intervals.

•  DSC HU/CM malfunction

Diagnostic procedure

STEP	INSPECTION		ACTION
1	VERIFY THE TIRE • Verify that the currently equipped tire type (size, supplier, and type) conform to the Mazda recommendation. (See WHEEL AND TIRE SPECIFICATION.) • Is the tire type as specified?	Yes	Go to the next step.
1		No	Replace the tire, then go to Step 3. (See WHEEL AND TIRE SPECIFICATION.)
2	MEASURE THE TIRE PRESSURE • Measure the tire pressure when the tires are cold. (See WHEEL AND TIRE SPECIFICATION.) • Is the pressure as specified?	Yes	Go to the next step.
2		No	Adjust the tire pressure to the specification when the tires are cold, then go to the next step. (See WHEEL AND TIRE SPECIFICATION.)
3	INITIALIZE THE TPMS • Initialize the TPMS. (See TIRE PRESSURE MONITORING SYSTEM INITIALIZATION PROCEDURE.) • Is the initialization normally completed?	Yes	Go to the next step.
3		No	Repeat the inspection from Step 1. If the malfunction recurs, replace the DSC HU/CM, then go to the next step. (See DSC HU/CM REMOVAL/INSTALLATION.)
4	VERIFY THAT THE SAME DTC IS NOT PRESENT • Clear the DTCs from the memory. (See ON-BOARD DIAGNOSIS [DYNAMIC STABILITY CONTROL (DSC)].) • Are the same DTCs present?	Yes	Repeat the inspection from Step 1. If the malfunction recurs, replace the DSC HU/CM, then go to the next step. (See DSC HU/CM REMOVAL/INSTALLATION.)
4		No	Go to the next step.
5	VERIFY THAT NO OTHER DTCS ARE PRESENT • Are any other DTCs output?	Yes	Go to the applicable DTC inspection. (See ON-BOARD DIAGNOSIS [DYNAMIC STABILITY CONTROL (DSC)].)
5		No	DTC troubleshooting completed.
