Scheme 1: DTC 151-11: Low Tire Air Pressure
Scheme 1: DTC 151-11: Low Tire Air Pressure

Note. Before troubleshooting, CHECK THE OUTSIDE AIR TEMPERATURE SENSOR . If outside air temperature sensor is failed, the VSA modulator-control unit may set this code. Make sure to avoid uneven loading on one side (left or right) of the vehicle and excessive loading. Make sure to inflate the tires to recommended pressure, not higher than the specified pressure, when TPMS calibration is done. Before you troubleshoot, record all freeze data and any on-board snapshot, and review the how to troubleshooting information.

151-11 Low Tire Air Pressure
  1. Tire check: 1. Turn the ignition switch to LOCK (0). 2. Check all four tires for size, inflation, and wear. Are all four tires the correct size, properly inflated, and worn evenly? YES : The system is OK at this time. Do the TPMS calibration. NO : Install the correct tires, a known-good set of tires, or set the tires to the correct pressure, and do the TPMS calibration.

Scheme 2: DTC 151-21: Different Diameter Tire Detection

Note. The DTC will be indicated when the vehicle has a different diameter tire(s) compared to the other tires. Check the record of using tires and wheels of a different size from originally supplied with the vehicle including the use of temporary spare tire. Before you troubleshoot, record all freeze data and any on-board snapshot, and review the how to troubleshooting information.

DTC DescriptionDTCFreeze Frame
91-1 VSA Activation Time Too Long
  1. Brake system check: 1. Turn the ignition switch to LOCK (0). 2. Check the brake system for leaks or mechanical problems. Is the brake system OK? (No brake fluid leakage, no air trapped in the brake system, no brake pads worn out.) YES : Go to step 2. NO : Repair the brake system.
  2. Problem verification: 1. Turn the ignition switch to ON (II). 2. Clear the DTC with the HDS. 3. Turn the ignition switch to LOCK (0). 4. Test-drive the vehicle in a straight line. Accelerate the vehicle up to 6 mph (10 km/h) or more, and stop, then accelerate up to 6 mph (10 km/h) or more. NOTE: Do the test-driving in a safe area. Drive the vehicle on the road, not on a lift. 5. Check for DTCs with the HDS. DTC Description DTC Freeze Frame 91-1 VSA Activation Time Too Long Is DTC 91-1 indicated? YES : The failure is duplicated. Go to step 3. NO : Intermittent failure, the system is OK at this time. Refer to intermittent failures troubleshooting.
  3. VSA modulator-control unit check (update): 1. Update the VSA modulator-control unit if it does not have the latest software See «VSA SENSOR NEUTRAL POSITION MEMORIZATION»(ref-595411-S26728862432014013100000) , «VSA MODULATOR-CONTROL UNIT REMOVAL AND INSTALLATION»(ref-595411-S13354206342014013100000) or «VSA MODULATOR-CONTROL UNIT UPDATE»(ref-595411-S33795849562014013100000) . 2. Turn the ignition switch to LOCK (0). 3. Test-drive the vehicle in a straight line. Accelerate the vehicle up to 6 mph (10 km/h) or more, and stop, then accelerate up to 6 mph (10 km/h) or more.
