DESCRIPTION
While the engine is being cranked, battery voltage is applied to terminal STA of the TCM.
If the TCM detects the starter control (STA) signal while the vehicle is being driven, it determines that there is a malfunction in the STA circuit. The TCM then illuminates the MIL and sets the DTC.
This monitor runs when the vehicle is driven at 20 km/h (12.4 mph) or more for over 20 seconds.
DTC Code | DTC Detection Condition | Trouble Area |
---|---|---|
P0617 | When conditions (a), (b) and (c) are met, positive (+B) battery voltage of 10.5 V or more is applied to TCM for 20 seconds (1 trip detection logic)
