DTC P0617 Starter Relay Circuit High


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 stores the DTC.
This monitor runs when the vehicle is driven at more than 20 km/h (12.4 mph) for over 20 seconds.

DTC Code
DTC Detection Condition
Trouble Area
P0617
All conditions are met (1-trip detection logic):
(a) Vehicle speed is more than 20 km/h (12.4 mph).
(b) Engine speed is more than 1000 rpm.
(c) STA signal is ON.
(d) Battery voltage (10.5 V or higher) is applied to the TCM for 20 seconds.

INSPECTION PROCEDURE

HINT:
The following troubleshooting flowchart is based on the premise that the engine can be cranked normally. If the engine does not crank, proceed to the problem symptoms table.
1.READ VALUE USING GTS (STARTER SIGNAL)

  1. Connect the GTS to the DLC3.

  1. Turn the ignition switch to ON.

  1. Turn the GTS on.

  1. Enter the following menus: Powertrain / ECT / Data List.

  1. Read the value displayed on the GTS.

  1. Crank the engine.

  1. Read the value displayed on the GTS.
