CUSTOMER CONCERN Accelerator pedal input produces no throttle response, and DTC P2112 is stored. CAUSE Throttle-plate inspection and circuit testing confirmed an internally sticking electronic throttle body. CORRECTION Remove and replace the failed electronic throttle-body assembly.

CUSTOMER CONCERN Customer states the steering wheel shakes slightly by itself while the vehicle is running and the wheel is centered. DTC B2278 is stored. CAUSE Power-steering testing confirmed a malfunctioning steering-shaft torque sensor. CORRECTION Remove and replace steering-shaft torque sensor. Perform steering-angle and torque-sensor calibration, clear DTC B2278 and verify steering operation.

CUSTOMER CONCERN Customer states the engine will not crank and numerous hybrid-system DTCs are stored. CAUSE The DTCs were shutdown effects from an electronics overheat condition, and testing confirmed the Motor Electronics Cooling System pump failed to circulate coolant. CORRECTION Remove and replace Motor Electronics Cooling System pump. Refill and bleed electronics cooling circuit, clear DTCs and verify pump operation.

CUSTOMER CONCERN Customer states the engine will not crank or start. No DTCs are stored and the theft indicator proves out normally. CAUSE Ignition-switch circuit testing confirmed the steering-column lock module was preventing the start command. CORRECTION Remove and replace steering-column lock module. Verify normal key operation and engine starting.

CUSTOMER CONCERN Customer states the brake pedal is low after replacement of a failed front brake hose. DTC C1525 is stored. CAUSE Air remained trapped in the electronically controlled hydraulic brake system because the required hybrid service-bleed routine had not been completed. CORRECTION Perform complete hybrid ABS bleed procedure with a compatible scan tool and pressure bleeder. Clear DTC C1525 and verify brake-pedal height.

CUSTOMER CONCERN Customer states the wrench warning light comes on intermittently. DTC B1239 is stored in the battery-control system. CAUSE Testing under TSB 07-25-12 confirmed the traction-battery auxiliary mode-door actuator failed to control cooling-air flow. CORRECTION Remove and replace traction-battery auxiliary mode-door actuator. Clear DTC B1239 and verify battery-cooling airflow control.

CUSTOMER CONCERN Customer states the brake pedal is low after replacement of a failed front brake hose. DTC C1525 is stored. CAUSE Air remained trapped in the electronically controlled hydraulic brake system because the required hybrid service-bleed routine had not been completed. CORRECTION Perform complete ABS service-bleed procedure with a compatible scan tool and pressure bleeder. Clear DTC C1525.

CUSTOMER CONCERN The Stop Safely warning came on while driving and DTCs P0A27 and P1A10 were stored. CAUSE The high-voltage traction-battery internal harness and calibration were confirmed as the fault. CORRECTION A jumper harness was installed in the high-voltage battery assembly and the battery calibration was updated.

CUSTOMER CONCERN A front brake hose failed and, after replacement, the brake pedal remained low while DTC C1525 set. CAUSE Air remained trapped in the electronically controlled hybrid brake system. CORRECTION The prescribed ABS service-bleed procedure was completed with compatible scan and pressure-bleeding equipment.

CUSTOMER CONCERN The check-engine light was on with DTC P0128. CAUSE The engine coolant thermostat was not maintaining the expected regulating temperature. CORRECTION The engine coolant thermostat was replaced.
