It is the EPS indicator that you should be checking.
Under normal conditions, the EPS indicator comes on when the ignition switch is turned to the ON (II) position, then goes off after the engine is started. This indicates that the bulb and its circuit are operating correctly.
If there is any trouble in the system after the engine is started, the EPS indicator will stay on, and the power assist is turned off.
When EPS indicator light comes on, the control unit memorizes the DTC. In this case, the control unit will not activate the EPS system after the engine starts again, but it keeps the EPS indicator on.
When DTC 12, 16, 17, 18, or 67 is stored in the control unit, the EPS indicator will stay on until the DTC is erased. When a problem is detected and the EPS indicator comes on, there are cases when the indicator stays on until the ignition switch is turned OFF, and cases when the indicator goes off automatically when the system returns to normal. Even though the system is operating normally, the EPS indicator will come on under the following conditions:
Condition 1 (CVT model only):
The A/T shift lever position is in other than N or P position.
The vehicle's speed is 1 mph (1 km/h) or below and engine is running at 1,900 rpm or above for 90 seconds (DTC 27).
When the vehicle speed is 6.2 mph (10 km/h) or above and the engine is running at 280 rpm or below for 3 seconds (DTC 23).
The shift lever is in neutral.
The clutch pedal is depressed.
The vehicle's speed is above 13 mph (20 km/h) for more than 60 seconds.
To determine the actual cause of the problem, question the customer about the conditions during which the problem occurred, taking the above conditions into consideration.
For code retrieval you either use a Honda Diagnostic System or manually use a jumper across terminal 4 and 9 of the DLC and read the blinking code of the EPS light with ignition switch turned on.
