Automatic Transaxle System

U660F AUTOMATIC TRANSMISSION / TRANSAXLE: AUTOMATIC TRANSAXLE SYSTEM: P0617: Starter Relay Circuit High
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 will turn on the MIL and store the DTC.

This monitor runs when the vehicle is driven at 20 km/h (12.4 mph) for over 20 seconds.

INSPECTION PROCEDURE

NOTICE:
Perform the universal trip to clear permanent DTCs DTC Check / Clear.

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 Symptom Related Diagnostic Procedures.

PROCEDURE

1. READ VALUE USING TECHSTREAM (STARTER SIGNAL)

(a) Connect the Techstream to the DLC3.

(b) Turn the ignition switch to ON.

(c) Turn the Techstream on.

(d) Enter the following menus: Powertrain / ECT / Data List / All Data /Starter Signal.

(e) Check the value displayed on the Techstream when the ignition switch is turned to ON and START.

OK

2. READ VALUE USING TECHSTREAM (STARTER SIGNAL)

(a) Turn the Techstream off.

(b) Turn the ignition switch off.

(c) Disconnect the park/neutral position switch connector.

(d) Turn the ignition switch to ON.

(e) Turn the Techstream on.

(f) Enter the following menus: Powertrain / ECT / Data List / All Data / Starter Signal.

(g) Check the value displayed on the Techstream when the ignition switch is turned to ON.

B -- INSPECT PARK/NEUTRAL POSITION SWITCH
A -- Continue to next step.

3. INSPECT TCM (STA VOLTAGE)

(a) Turn the ignition switch off.

(b) Disconnect the ECM connector.





(c) Disconnect the power management control ECU connector (w/ Smart Key System).

(d) Connect the park/neutral position switch connector.

(e) Disconnect the TCM connector.

(f) Measure the voltage according to the value(s) in the table below.
