20. Check TPMS DATA LIST for RF, LF, RR, and LR TIRE PRESSURE SENSOR SIGNAL STATUS changing to NORMAL with the HDS.

NOTE: If the HDS screen shows UNDEFINED for sensor status, turn the ignition switch to LOCK (0), rotate the tire 1/4 turn, then turn the ignition

switch to ON (II), and try again. If UNDEFINED is still displayed, repeat this procedure until NORMAL is shown.

Is NORMAL indicated within one full turn of the tire?

YES -

Replace the tire pressure sensor on the client's wheel See: Instrument Panel, Gauges and Warning Indicators/Tire Monitoring System/Tire Pressure

Sensor/Service and Repair.?

NO -

Go to step 21.

21. Turn the ignition switch to LOCK (0).

22. Disconnect the appropriate initiator 3P connector.

23. Disconnect the TPMS control unit 20P connector See: Instrument Panel, Gauges and Warning Indicators/Tire Monitoring System/Tire

Pressure Module/Service and Repair.

24. Check for continuity between TPMS control unit 20P connector terminal No. 20 and the appropriate initiator 3P connector terminal No. 1.

4. Check the SUS STROKE_S VOLTAGE (RF), (LF), (RR), or (LR) in the ACTIVE DAMPER SYSTEM DATA LIST with the HDS while

moving the suspension stroke sensor arm through a complete stroke. Compare the voltage/rotation angle between the chart and the

measurements.

NOTE: The voltage should increase (decrease) within 90 degrees of the sensor arm rotation from the first voltage change point.

Is the voltage as specified?

YES -

Replace the active damper control unit See: Relays and Modules/Relays and Modules - Steering and Suspension/Relays and Modules -

Suspension/Suspension Control Module/Service and Repair.?

NO -

Replace the appropriate suspension stroke sensor See: Sensors and Switches/Sensors and Switches - Steering and Suspension/Sensors and

Switches - Suspension/Ride Height Sensor/Service and Repair.?

DTC 2-5:

Right-front/Right-rear Suspension Stroke Sensor Range/Performance Problem

DTC 2-6:

Left-front/Left-rear Suspension Stroke Sensor Range/Performance Problem

1. Turn the ignition switch to LOCK (0).

2. Remove the appropriate suspension stroke sensor See: Sensors and Switches/Sensors and Switches - Steering and Suspension/Sensors and

Switches - Suspension/Ride Height Sensor/Service and Repair. Do not disconnect the sensor connector.

NOTE: After troubleshooting for the left side suspension stroke sensor, do the headlight initial position learning procedure See: Lighting and

Horns/Testing and Inspection/Programming and Relearning.

3. Start the engine, and wait 5 seconds.

4. Check the SUS STROKE_S VOLTAGE (RF), (LF), (RR), or (LR) in the ACTIVE DAMPER SYSTEM DATA LIST with the HDS while

moving the suspension stroke sensor arm through a complete stroke. Compare the voltage/rotation angle between the chart and the

measurements.

NOTE: The voltage should increase (decrease) within 90 degrees of the sensor arm rotation from the first voltage change point.
