DTC P0617 Starter Relay Circuit High |
DESCRIPTION
While the engine is being cranked, the 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 sets the DTC.This monitor runs when the vehicle is driven at 20 km/h (12.4 mph) for over 20 seconds.DTC No.

WIRING DIAGRAM
INSPECTION PROCEDURE
- HINT:
- The following troubleshooting flowchart is based on the premise that the engine is cranked normally.
If the engine does not crank, proceed to the problem symptoms table (CAMRY_ACV40 RM000000PDG018X.html).
- Read freeze frame data using the intelligent tester. The ECM records vehicle and driving condition information as freeze frame data the moment a DTC is stored. When troubleshooting, freeze frame data can help determine if the vehicle was moving or stationary, if the engine was warmed up or not, if the air-fuel ratio was lean or rich, and other data from the time the malfunction occurred.
1.READ VALUE USING INTELLIGENT TESTER (STARTER SIGNAL) |
Connect the intelligent tester to the DLC3.
Turn the ignition switch to the ON position and turn the tester on.
Select the following menu items: Powertrain / Engine and ECT / Data List / Starter Signal.
