DESCRIPTION

While the engine is being cranked, positive battery voltage is applied to terminal STA of the ECM.

If the ECM detects the starter control (STA) signal while the vehicle is being driven, it determines that there is a malfunction in the STA circuit. The ECM then illuminates the MIL and stores the DTC.

This monitor runs when the vehicle has been driven at 20 km/h (12.5 mph) or more for more than 20 seconds.

Table 1. P0617
DTC Detection Drive Pattern DTC Detection Condition Trouble Area

Conditions (a), (b) and (c) are met for 20 seconds

(a) Vehicle speed is more than 20 km/h (12.5 mph).

(b) Engine speed is more than 1000 rpm.

(c) STA signal is on.

INSPECTION PROCEDURE

Note:

  • Inspect the fuses of circuits related to this system before performing the following inspection procedure.

  • After replacing the ECM, the new ECM needs registration (Click here) and initialization (Click here).

Tip:

  • The following troubleshooting process is based on the premise that the engine can crank normally. If the engine does not crank, proceed to the Problem Symptoms Table (Click here).

  • If this DTC is output, inspect the starter.
