AA80E Automatic Transmission

AA80E AUTOMATIC TRANSMISSION: AUTOMATIC TRANSMISSION SYSTEM: P0617: Starter Relay Circuit High
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) or more for over 20 seconds.
