ECD SYSTEM(for DPF), Diagnostic DTC:P0617

DTC Code DTC Name
P0617 Starter Relay Circuit High

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.

DTC No.

CAUTION / NOTICE / HINT

Note:

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.

PROCEDURE

  1. READ VALUE USING GTS (STARTER SIGNAL)

    1. Connect the GTS to the DLC3.

    2. Turn the ignition switch to ON and turn the GTS on.

    3. Enter the following menus: Powertrain / Engine and ECT / Data List / Starter Signal.

    4. Read the value displayed on the GTS when the vehicle is driven at 20 km/h (12.4 mph) or more.

      Note:

      When performing the confirmation driving pattern, obey all speed limits and traffic laws.
