DTC 26, VES Output Circuit (CKT Open Or Shorted To Ground): Notes

Variable Effort Steering (VES) enable circuit, VES Pulse Width Modulated (PWM) output circuit and power steering pump/EVO actuator conduct Pulse Width Modulation (PWM) for variable effort system. CCM has ability to detect problem in VES circuits.

DTC 26 will set when ignition switch is in RUN position, VES function is off, VES enable circuit is not grounded by CCM, and CCM terminal C13 voltage is less than 2 volts (102 A/D counts). CCM checks for fault once each ignition cycle and will set DTC if fault is present.

When DTC 26 is set, VES enable circuit, VES (PWM) output circuit or power steering pump/EVO actuator is open or shorted to ground. DTC 26 will clear if fault goes away for 2 or more seconds.
