TPMS: Avoid tire/tool valve contact on Kia Souls
SUBJECT VEHICLE: 2010 Kia Soul.
RELEARN PROCEDURE? Yes.
SPECIAL TOOLS NEEDED? Yes, a TPMS Exciter Scan Tool
The tire pressure monitoring system (TPMS) on the 2010 Kia Soul uses a receiver, four radio frequency (RF) sensors, two warning indicators on the instrument cluster and a data circuit to perform system functions. When the tire pressure is below the allowed threshold, the low pressure indicator on the instrument cluster will be illuminated. If the system detects a receiver or sensor fault, or if it detects a fault that is external to the receiver or sensor, the TPMS warning indicator on the instrument cluster will be illuminated. If the fault is considered “critical,” the light will stay on throughout the entire ignition cycle.
The TPMS sensors operate in two modes: stationary/rolling mode and sleep mode. In stationary/rolling mode, the sensor will measure pressure and temperature every four seconds, and measure acceleration every 60 seconds. In sleep mode the sensor enters a low current consumption state where no measurements are made in order to conserve battery power.
All sensors are in this state when new.
To remove and old sensor, follow these steps. NOTE: If the tire pressure sensor is replaced, it will need to be initiated.
1. Remove the wheel and tire assembly.
2. Deflate the tire and remove the balance weights. The tire bead should be broken about 11 inches from the valve inside the wheel. The bead breaker should not be set too deep. Demount should end near the valve.
3. While supporting the sensor with care, remove the valve nut and remove the sensor assembly. CAUTION: The seal and seal washer should not be re-used — remove and discard.
4. While supporting the rear of the valve so there is no movement, remove the seal and seal washer.
Easy on the lube
To install a new sensor, follow these steps. CAUTION: Avoid bringing the tire pressure sensor in contact with lubricant. Always handle the tire pressure sensor carefully.
1. While supporting the rear of the valve so there is no movement, install the new seal and seal washer (see Figure 1).
2. Ensure that the valve hole and mating face of the wheel are clean. Insert the sensor assembly into the wheel without modifying the angle of the valve stem. The fit should not be tight. CAUTION: Ensure the sensor feet are against the wheel throughout the remainder of the assembly process.
3. Tighten the nut by hand until it is lightly in contact with the wheel (see Figure 2). CAUTION: While tightening the nut, do not exceed the allowed torque. Do not use electric or pneumatic tools.
4. Using a torque wrench, tighten the nut to 5.5-6.2 ft.-lbs. (7.5-8.5 N.m).
5. Lubricate the tire bead, but not the rim. Do not use excessive lubrication.
6. Start the tire mounting about 5.9 inches from the valve. Move the mounting tool away from the valve. Avoid tire/tool contact with the valve. Finish with the mounting tool near the valve.
7. Adjust the inflation pressure of all wheels. Install the valve cap.
8. If installing a new sensor, initiate the tire pressure sensor.
Ready, set – reset!
If a tire pressure sensor is replaced, it will need to be initiated. To initiate a new sensor, follow these steps. NOTE: In the following procedure, a TPMS exciter scan tool must be used.
1. Turn the ignition ON with the engine OFF.
2. Holding a TPMS exciter within 3 inches of the sensor valve, read each tire pressure sensor ID in the following order: front-left; front-right; rear-left; rear-right.
3. Press the ENTER button as each tire is illuminated on the screen.
4. Press the WRITE button after reading all of the sensor IDs.
5. Connect the TPMS exciter to the Data Link Connector located under the left side of the instrument panel. Register the four sensor IDs to the receiver.
NOTE: The TPMS receiver will complete the learn procedure of the new sensor(s) after the vehicle is driven up to 20 minutes at speeds over 15.5 mph.
6. Modify any sensor ID and press the OK button.
NOTE: For the system to correctly monitor the tires for under-inflation, there should be a total of exactly four sensors, one on each of the four road wheel positions. There should be no other sensors in the vehicle since this could cause the system to monitor the wrong sensors or fail to learn a new sensor. ■
