AUTOMATIC TRANSAXLE SYSTEM, Diagnostic DTC:P0617
| DTC Code | DTC Name |
|---|---|
| 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.

WIRING DIAGRAM
CAUTION / NOTICE / HINT
Perform registration and/or initialization when parts related to the automatic transaxle are replaced.
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.

for 2AD-FHV:
Read freeze frame data using the GTS. The TCM records vehicle and driving condition information as freeze frame data the moment a DTC is stored. When troubleshooting, freeze frame data can be helpful in determining whether the vehicle was moving or stationary, whether the engine was warmed up or not, whether the air-fuel ratio was lean or rich, as well as other data recorded at the time of a malfunction.
