Pinpoint Test 1: Transaxle Control Solenoids: Notes

NOTE:

Refer to the transaxle connector illustrations and solenoid body leadframe internal wiring diagram preceding these pinpoint tests. See TRANSAXLE CONNECTOR LAYOUTS .

TRANSAXLE CONTROL SOLENOIDS DIAGNOSTIC PROCEDURE

PINPOINT TEST 1		SHIFT SOLENOIDS
STEP	INSPECTION		ACTION
1	ELECTRONIC DIAGNOSTICS Check to make sure the transaxle harness connector is fully seated, terminals are engaged in connector and in good condition before proceeding. Connect the diagnostic tool. Carry out the KOEO until continuous DTCs have been displayed. Enter the Output Test Mode. Select the mode ALL ON. Push START to turn outputs ON. Push STOP to turn outputs OFF. Does vehicle enter Output Test Mode?	Yes	GO to the next step.
1		No	PRESS START. If vehicle does not enter Output Test Mode, see SYMPTOM TROUBLESHOOTING - 2.5L AND 3.0L - TRIBUTE .
2	CHECK THE SOLENOID CIRCUIT FOR AN OPEN Key in OFF position. Disconnect transaxle vehicle harness transmission 0140-131 (2.5L), 0140-231 (3.0L). Use a mirror to inspect both ends of the connector for damage or pushed-out pins, corrosion, loose wires and missing or damaged seals. Disconnect PCM transaxle harness 0140-175t. Use a mirror to inspect both ends of the connector for damage or pushed-out pins, corrosion, loose wires and missing or damaged seals. Measure the resistance of the suspect solenoid circuit between the PCM transaxle harness 0140-175T and transaxle vehicle harness 0140-131 (2.5L), 0140-231 (3.0L). See Step 2 chart at the end of this pinpoint test. Is the resistance less than 5 ohms?	Yes	GO to the next step.
2		No	REPAIR the circuits for an open. RECONNECT all components. TEST the system for normal operation.
3	CHECK THE SOLENOID CIRCUIT FOR A SHORT TO GROUND Measure the resistance between the transaxle vehicle harness 05118-168A, harness side and ground. See Step 3 chart at the end of this pinpoint test. Is the resistance greater than 10,000 ohms?	Yes	GO to the next step.
3		No	REPAIR the circuit(s) for a short to ground. RECONNECT all components. TEST the system for normal operation.
4	CHECK THE SOLENOID CIRCUIT FOR A SHORT TO POWER Measure the voltage between the transaxle vehicle harness electrical 0518-168, harness side and ground using Step 4 chart below. Is any voltage present?	Yes	REPAIR the circuit(s) for a short to power. RECONNECT all components. TEST the system for normal operation.
4		No	GO to the next step.
5	CHECK THE RESISTANCE OF THE SOLENOID FIELD CIRCUIT Measure the resistance between the transaxle solenoid body leadframe main electrical connector 05118-168a-5, component side and the suspect solenoid pin, component side and compare the value to the specifications in the Step 5 Charts below. Is the resistance within specifications?	Yes	INSTALL a new PCM. See POWERTRAIN CONTROL MODULE (PCM) REMOVAL/INSTALLATION -- 2.5L AND 3.0L . RECONNECT all components. TEST the system for normal operation.
5		No	REMOVE the main control cover. See MAIN CONTROL COVER REMOVAL/INSTALLATION . INSPECT the solenoid body for foreign material such as metal shavings on the exposed metal contacts or other components. CLEAR the solenoid body and RECHECK the resistance values. If the resistance values are still out of specification, GO to the next step. INSTALL a new solenoid(s). See SOLENOIDS REMOVAL/INSTALLATION . RECONNECT all components. TEST the system for normal operation.
6	CHECK THE SOLENOID BODY LEADFRAME FOR AN OPEN Remove the solenoid body leadframe. See SOLENOID BODY LEADFRAME REMOVAL/INSTALLATION . Measure the resistance between the solenoid body leadframe main electrical connector 05118-168, component side and the corresponding solenoid pins. See Step 6 chart at the end of this pinpoint test. Is the resistance less than 5 ohms?	Yes	INSTALL a new solenoid(s). See SOLENOIDS REMOVAL/INSTALLATION . RECONNECT all components. TEST the system for normal operation.
6		No	INSTALL a new solenoid body leadframe. See SOLENOID BODY LEADFRAME REMOVAL/INSTALLATION .
