READ VALUE USING INTELLIGENT TESTER (STARTER SIGNAL)
INSPECT PARK/NEUTRAL POSITION SWITCH ASSEMBLY
DTC 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.
DTC Code | DTC Detection Condition | Trouble Area |
P0617 | All conditions are met (1-trip detection logic): (a) Vehicle speed is more than 20 km/h (12.4 mph). (b) Engine speed is more than 1000 rpm. (c) STA signal is ON. (d) Battery voltage (10.5 V or higher) is applied to the TCM for 20 seconds. |

INSPECTION PROCEDURE
- HINT:
- 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 (LandCruiser RM0000012WF0ABX.html).
- Read freeze frame data using the intelligent tester. 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 (LandCruiser RM000000PDS15BX.html).

2.CHECK TCM (STA VOLTAGE) |
Disconnect the G69 TCM connector.
![]() |
Measure the voltage according to the value(s) in the table below.
- Standard Voltage:
Tester Connection Condition Specified Condition G69-11 (STA) - Body ground Ignition switch ON and shift lever in P or N Below 2 V
Turn the ignition switch off.
Measure the resistance according to the value(s) in the table below.
- Standard Resistance:
Tester Connection Condition Specified Condition G69-1 (E1) - Body ground Always Below 1 Ω
