If the freeze data/on-board snapshot of this DTC is recorded, try to reproduce the failure under the same conditions with the freeze data/on-board snapshot.
- Tire check
- 1. Turn the vehicle to the OFF (LOCK) mode.
- 2. Check all four tires for size, inflation, and wear. Refer to:
Wheel Alignment (2014 2015 2016)
Are all four tires the correct size, properly inflated, and worn evenly?
YES
Go to step 3.
NO
Swap the wheels and tires with a known-good set (the correct size, type, and properly inflated), then retest-drive the vehicle.
- Wheel speed sensor performance check
- 1. Test-drive the vehicle at 12 mph (20 km/h) or more in a straight line.
NOTE: Drive the vehicle on the road, not on a lift.
- 2. Check the parameter (s) below with the HDS.
Signal Current conditions Values Unit RIGHT FRONT WHEEL SPEED LEFT FRONT WHEEL SPEED RIGHT REAR WHEEL SPEED LEFT REAR WHEEL SPEED Is any one of the four values different?
YES
Go to step 4.
NO
Check for loose terminals and poor connections in the VSA modulator-control unit 38P connector. If they are OK, replace the VSA modulator-control unit .
- Wheel speed sensor check (substitution)
- 1. Turn the vehicle to the OFF (LOCK) mode.
- 2. Substitute a known-good wheel speed sensor. Refer to:
Wheel Speed Sensor Removal and Installation (2014 2015 2016) , or
