Trouble Code: P0615



Starter Relay Control Circuit

Possible Causes:



Ignition system DTCs set with the ignition switch in the Crank position if the starter relay or the starter is inoperative. When the ECM enables starter operation, the ECM also initiates the diagnostic test routines for DTCs P0335, P0340, and P0385. If a condition exists which prevents the engine from cranking, the ECM will not receive signal input from the crankshaft position (CKP) and camshaft position (CMP) sensors, and the DTCs will set. Reviewing the Fail Records vehicle mileage since the diagnostic test last failed may assist in diagnosing the condition. The information may help determine how often the condition that set the DTC occurs.

| Front of Vehicle |



Use the J 35616-A/BT-8637 Connector Test Adapter Kit for any test that requires probing the ECM harness connector or a component harness connector.
 
Inspect for a condition in which the throttle valves may have been held open. For example, ice may have formed in the throttle bore causing the throttle valve not to close. Observe the Freeze Frame/Failure Records.
 
The throttle valves are spring loaded to a slightly open position. The throttle valves should be open approximately 3-5 percent. This is referred to as the rest position.
 
The throttle valve should not be completely closed or open any more than a specified amount.
 
The throttle valve should move open and to the closed position without binding under the normal spring pressure.
 
The throttle should NOT be free to move open or closed WITHOUT spring pressure.
 
The scan tool has the ability to operate the throttle control system using the TP function located in the TAC System menu. This function operates the throttle valve through the entire range in order to determine if the TAC system operates correctly. Additional DTCs may set using this function.
 
For an intermittent condition, refer to Intermittent Conditions .
 

Trouble Code: P0645



Air Conditioning (A/C) Clutch Relay Control Circuit

Possible Causes:



Important: Inspect PCM/ECM engine grounds for being secure and clean. If DTC P0645 cannot be duplicated, review the Failure Records. Observe the vehicle mileage since the diagnostic test last failed. This may help to determine how often the condition which caused the DTC to set occurs. This may assist in diagnosing the condition. If the condition is intermittent, refer to Testing for Intermittent Conditions and Poor Connections .
