Description<\/span><\/div>\n<\/td>\n
\n
\u2022 Cylinder deactivation control does not operate.<\/div>\n<\/td>\n<\/tr>\n
\n
Possible cause<\/span><\/div>\n<\/td>\n
\n
\u2022 Cylinder deactivation control is in inhibit mode due to any of the following conditions<\/div>\n
\n
\n
Due to customer’s driving operation or vehicle conditions<\/div>\n<\/dd>\n
\n
\u2015 Selector lever position is P, N or R position (ATX)<\/div>\n
\u2015 Shift lever position: Any neutral, reverse, or low speed gear (MTX)<\/div>\n
\u2015 Vehicle speed: 5 km\/h {3 mph} or less<\/span><\/div>\n
\u2015 Engine speed: 1,000 rpm or less<\/span>, or 3,600 rpm or more<\/span><\/div>\n<\/dd>\n<\/dl>\n
\n
\n
Other<\/div>\n<\/dd>\n
\n
\u2015 Characteristic learning *1<\/sup> for cylinder deactivation system-related parts is not completed<\/div>\n
\u2015 Engine torque is larger than specified value<\/div>\n
\u2015 Insufficient engine warm-up<\/div>\n
\u2015 Engine coolant or engine oil temperature is high<\/div>\n
\u2015 During or directly after DSC operation<\/div>\n
\u2015 Cylinder deactivation control continues for long periods<\/div>\n
\u2015 Cylinder deactivation system-related part malfunction<\/div>\n
\u2015 Battery voltage is extremely low<\/div>\n<\/dd>\n<\/dl>\n
*1<\/sup>: To perform cylinder deactivation control, the PCM performs the crankshaft installation tolerance learning and learns the individual differences (variations) of the sensor which occurs during the manufacturing of the engine oil pressure sensor relative to the cylinder deactivation control-related parts.<\/div>\n
\n
\n
Warning<\/div>\n<\/dd>\n
\n
\u2022 The crankshaft installation tolerance learning and the engine oil pressure sensor variation learning are performed at the following timing, however it could result in an accident. Explain to the customer that the vehicle is not to be driven to perform learning for the PCM intentionally.<\/div>\n<\/dd>\n<\/dl>\n
Crankshaft installation tolerance learning<\/div>\n
\u2022 While deceleration continues for approx. 6 s<\/span> with accelerator pedal released and brake pedal released while driving at a speed of approx. 60 km\/h {37 mph} or more<\/span><\/div>\n
Engine oil pressure sensor variation learning<\/div>\n
\u2022 During 11 s<\/span> while vehicle is stopped after ignition switched OFF<\/div>\n
\n
\n
Note<\/div>\n<\/dd>\n
\n
\n
\u2022 The inhibit conditions relative to the driving condition directly before cylinder deactivation control is not implemented can be verified by using the M-MDS function.<\/div>\n
\u2022 This function indicates the [Other] conditions which frequency is high as a reason that cylinder deactivation control is inhibited for the driving operation and driving range available for cylinder deactivation.<\/div>\n<\/div>\n<\/dd>\n<\/dl>\n<\/td>\n<\/tr>\n
