General Description

The powertrain control module (PCM) detects a malfunction by comparing the motor pulses presumed from the engine speed and the motor speed, and the motor pulses measured by the motor control module (MCM) / battery condition monitor module (BCM). If the actual motor pulse is out of range compared to the presumed motor pulse, the PCM detects a malfunction and stores a DTC.

Monitor Execution, Sequence, Duration, DTC Type 

Execution	Once per driving cycle
Sequence	None
Duration	6.0 seconds or more, but not more than 24 seconds
DTC Type	Two drive cycles, MIL on

Enable Conditions 

Condition		Minimum	Maximum
Engine speed [Engine Speed]		500 RPM	2, 000 RPM

[ ]: HDS Parameter

Malfunction Threshold 

When the generator motor pulse count is different from the crank pulse count by 127 or less or by 154 or more.

Possible Cause 

Confirmation Procedure 

Operating Condition 

1. Enter the maintenance mode, then start the engine.
2. Engine speed [Engine Speed] between 500 - 2, 000 RPM for at least 24 seconds

• When freeze data is stored, hold the engine speed under those conditions.

With the HDS 

None.

Diagnosis Details 

Conditions for setting the DTC 

When a malfunction is detected during the first drive cycle, a Pending DTC is stored in the PCM memory. If the malfunction returns in the next (second) drive cycle, the MIL comes on and a Confirmed DTC and the freeze data are stored.

Conditions for clearing the DTC 

The MIL is cleared if the malfunction does not return in three consecutive trips in which the diagnostic runs. The MIL, the Pending DTC, the Confirmed DTC, and the freeze data can be cleared with the scan tool Clear command or by disconnecting the 12 volt battery.
