Honda CR-V: Memorizing the Tire Pressure Sensor ID

Special Tools Required

TPMS sensor initializer tool AKS0620006 Available through the American Honda Tool and Equipment program, 888-424-6857.

All four tire pressure sensor IDs must be memorized to the TPMS control unit whenever you do any of these actions:

NOTE:

1. With the ignition switch OFF, connect the HDS to the data link connector (DLC) (A) located under the driver's side of the dashboard.

2. Turn the ignition switch ON (II).

3. Make sure the HDS communicates with the vehicle and the TPMS control unit. If it doesn't, troubleshoot the DLC circuit.

4. Hold the TPMS sensor initializer tool near one wheel, and memorize the pressure sensor ID by following the screen prompts on the HDS.

NOTE:

5. Repeat step 4 for each wheel until all four sensor IDs are memorized. When all four IDs are memorized, the low tire pressure indicator blinks.

6. Turn the ignition switch OFF.

7. Test-drive the vehicle at 28 mph (45 km/h) or more for at least 1 minute.

8. Make sure the low pressure indicator does not blink.

9. Turn the ignition switch OFF.

10. Reduce the pressure in one tire until it is less than the appropriate specification.

11. Turn the ignition switch ON (II).

NOTE: If it has been 5 minutes or more since the end of the last test-drive, reactivate the appropriate tire pressure sensor with the TPMS sensor initializer tool.

12. Test-drive the vehicle at 28 mph (45 km/h) or more for at least 1 minute.

13. Make sure the low pressure indicator turns on, then inflate the tire.

14. Repeat steps 9 through 13 for all the other tires.

15. Clear any DTCs with the HDS.

Tire Pressure Sensor Location

Special Tools Required

TPMS sensor initializer tool AKS0620006 Available through the American Honda Tool and Equipment program, 888-424-6857.

This procedure locates where tire pressure sensors 1, 2, 3, and 4 are mounted.

When the activate sensor signal is sent to each wheel using the TPMS sensor initializer tool in sequence, you can locate the tire pressure sensors by the reaction sensor number.

The sensor locations change in these cases:

1. With the ignition switch OFF, connect the HDS to the data link connector (DLC) (A) located under the driver's side of the dashboard.

2. Turn the ignition switch ON(II).

3. Make sure the HDS communicates with the vehicle and the TPMS control unit. If it doesn't, troubleshoot the DLC circuit.

4. Follow the prompts on the HDS to active the tire pressure sensors using the TPMS sensor initializer tool. Start with the left-front (LF) wheel.

5. Check the HDS screen, and note the active sensor reception order of tire pressure sensors 1, 2, 3, and 4.

NOTE: An example is shown. The sensor signals are received by the TPMS control unit in this order; sensor 1-fourth, sensor 2-second, sensor 3-third, and sensor 4-first.

6. Note the sensor location for reference.

7. Turn the ignition switch OFF.

System Description

TPMS Control Unit Inputs and Outputs for 20P Connector

Honda CR-V. TPMS (Tire Pressure Monitoring System)

System Structure

Once the vehicle speed exceeds 28 mph (45 km/h), the TPMS control unit monitors all four tires and the system. If it detects low pressure in a tire, it alerts the driver by turning on the low pressure indicator. If it detects a problem in the system, it turns on the TPMS indicator.

Control unit

Mounted in the middle of the dashboard, the TPMS control unit receives pressure sensor ID signals every time the vehicle speeds exceeds 28 mph (45 km/h). It also receives signals from the transmitters for tire pressure and the sensor condition, and it continuously monitors and controls the system.

Indicators

Two indicators are in the gauge control module: The low pressure indicator comes on when any tire pressure is low, and the TPMS indicator that comes on only if there's a problem with the system.

The low pressure indicator alerts the driver that a tire(s) pressure is low, but does not specify the tire(s) location.

Honda CR-V. TPMS (Tire Pressure Monitoring System)

Tire pressure sensor

Each sensor is an integrated unit made up of the tire valve stem, a pressure sensor, and a transmitter. The unit is attached to the inside of the wheel, around the valve stem. The sensor transmits the internal tire information to the control unit once every 60 seconds when the vehicle speed exceeds 28 mph (45 km/h). When the TPMS control unit receives a tire pressure signal that is less than 168 kPa (1.7 kgf/cm2, 24 psi), the control unit then turns on the low pressure indicator. When that tire's pressure is increased to more than 190 kPa (1.9 kgf/cm2, 28 psi), and the vehicle is driven above 28 mph (45 km/h) the transmitter sends the tire pressure signal to the control unit, and then the control unit turns the indicators off.

Do not mix the tire pressure sensor with another TPMS type.

Wheels

TPMS will not work unless TPMS type wheels are installed on the vehicle. The original equipment wheels have a "TPMS" mark (A) on them and counterweights (B) cast into the opposite side of the spoke to counter balance the weight of the tire pressure sensor (C).

NOTE: The vehicle is equipped with either aluminum or steel wheels.

System Communication

NOTE: Be careful not to bend the brackets on the TPMS control unit. Misalignment of the control unit could interfere with sending and receiving signals.
