Circuit Description
Battery voltage is supplied to power steering pump actuator terminal A when the EBCM commands the Electronic Brake Control Relay ON. Ground for the actuator is provided through EBCM terminal 18 to actuator terminal B. The EBCM controls the amount of current supplied to the actuator based on input from the ABS wheel speed sensors and the steering wheel position sensor.
Conditions for Setting the DTC
• DTC C1274 can be set anytime after ABS initialization.
• Excessive voltage drop across the power steering pump actuator driver.
Action Taken When the DTC Sets
• A malfunction DTC stores.
• VES is disabled and power steering returns to full assist.
• ABS remains functional.
Conditions for Clearing the DTC
• The condition responsible for setting the DTC no longer exists and the scan tool CLEAR DTCs function is used.
• 100 drive cycles pass with no ABS DTCs detected. A drive cycle consists of starting the vehicle, driving the vehicle over 16 km/h (10 mph), stopping and then turning the ignition OFF.

the EBCM is going "wtf? theres something wrong with your steering!" and im sure there are times where if a modual could it would flash a light that looks like the finger... and not abs lol
