uuIndicator, Coming On/Blinking uIf the Electric Power Steering (EPS) System Indicator Comes On
Handling the Unexpected
If the Electric Power Steeri ng (EPS) System Indicator 
Comes On
■Reasons for the indicator to come on
• Comes on when there is a problem with the EPS system.
• If you depress the accelerator peda l repeatedly to increase the motor 
speed while the motor is idling,  the indicator comes on, and 
sometimes the steering wheel becomes harder to operate.
• Comes on when the EPS steering angle center point memory is lost. 
This could be due to a number of problems including: battery 
disconnection, main fuse blow, low battery causing the reset of the 
EPS system, wire damage to EPS ha rness. Vehicle Stability Assist 
(VSA ®), VSA ® OFF, Collision Mitigation Braking System
TM (CMBSTM), 
and low tire pressure/TPMS indicato rs come on along with a message 
in the driver information interface.
■What to do when th e indicator comes on
• Stop the vehicle in a safe place,  turn off the power system, and turn 
on the power system again.
If the indicator re-appears and stay s on, immediately have your vehicle 
inspected by an authorized Honda Clarity Plug-In Hybrid dealer.
• If VSA ® indicator, VSA ® OFF indicator, CMBS
TM indicator, and low tire 
pressure/TPMS indicator come on al ong with a message in the driver 
information interface, you need to  calibrate the VSA and EPS systems.
Drive a short distance at more than  12 mph (20 km/h) to calibrate the 
VSA and EPS systems.
If the indicators come on and stay on, park your vehicle in a safe 
place, turn off and turn on the po wer system, then repeat the above 
operation.
If the indicators still come on and stay on, immediately have your 
vehicle inspected by an authorized  Honda Clarity Plug-In Hybrid dealer.
