AUTOMATIC TRANSMISSION SYSTEM, 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 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 20 km/h (12.4 mph) for over 20 seconds.

DTC No. DTC Detection Condition Trouble Area
P0617

When conditions (a), (b) and (c) are met, and positive (+B) battery voltage of 10.5 V or higher is applied to the TCM for 20 seconds

(1 trip detection logic)


  • (a) Vehicle speed is 20 km/h (12.4 mph) or more

  • (b) Engine speed is more than 1000 rpm

  • (c) STA signal is ON

  • Park/neutral position switch

  • Starter relay circuit

  • Cranking holding function circuit

  • Harness and connector

  • TCM
