CUSTOMER CONCERN The engine starts on the 12-volt starter, but the hybrid system does not operate. DTCs U1205 and U0037 are stored. CAUSE CAN-network testing confirmed an internal Motor Control Module failure. Module communication was intermittent, and scan-tool parameter data was incomplete when communication was available. CORRECTION Remove and replace the Motor Control Module, program the replacement module, and verify hybrid-system operation.

CUSTOMER CONCERN The engine intermittently runs rough and has low power with DTC P0339 stored. CAUSE Power, ground, signal-circuit, and pattern checks confirmed an intermittent crankshaft-position sensor failure. CORRECTION Remove and replace the crankshaft-position sensor, then perform the crankshaft-pattern clear and relearn.

CUSTOMER CONCERN The engine idles too high after throttle-body cleaning, and DTC P0507 may return intermittently. CAUSE The throttle-position learned value was not reset after service, leaving the idle control strategy out of calibration. CORRECTION Reset the throttle-position learned value and perform the idle relearn procedure.

CUSTOMER CONCERN The check engine, brake, TPMS, IMA, and stability-control warning lights come on when engine-compartment temperature rises; the vehicle operates normally when cold. CAUSE Heat testing confirmed an internal temperature-sensitive failure in the Powertrain Control Module. CORRECTION Remove and replace the Powertrain Control Module.

CUSTOMER CONCERN The check engine and IMA warning lights are on with DTC P0A7F stored. CAUSE Battery-module testing and the applicable Honda bulletin confirmed deterioration inside the high-voltage IMA battery. CORRECTION Remove and replace the high-voltage IMA battery, then update the Motor Control Module with the applicable calibration.
