Downloaded from www.Manualslib.com manuals search engine 4.CHECK SHIFT SOLENOID VALVE 2 (SSV2) POWER SUPPLY
• Turn the ignition switch on.
• Check power supply between shift solenoid valve 2
(SSV2) E-037 terminal B8 and ground in the A/T
assembly connector E-037.
• Voltage should be more than 12 V.
• Or using the appropriate diagnostic test tool and a digital multimeter perform the following:
• Check the EVS2 solenoid supply voltage between TCM pin 1 and TCM pin 9 when activating the EVS2 sole-
noid and deactivating the EVS2 solenoid.
• Check the shift solenoid control signal. Check the voltage of the shift solenoid in each shift position.
• Check the voltage of the EVS2 solenoid supply circuit between the transaxle assembly electrical connector pin
B3 and pin B8.

DTC Confirmation Procedure:
Before performing the following procedure, confirm that battery voltage is more than 12 V.
• Turn ignition switch off.
• Connect the X-431 scan tool to the Data Link Connector (DLC) - use the most current software available.
• Turn ignition switch on.
• With the scan tool, record and erase stored DTCs in the TCM.
• Start engine and warm it to normal operating temperature.
• With the scan tool, select view DTC and data stream.
• If the DTC is detected, the DTC condition is current. Go to Diagnostic Procedure - Step 1.
• If the DTC is not detected, the DTC condition is intermittent (See Diagnostic Help and Intermittent DTC Trou-
bleshooting in Section 08 Transaxle & Transfer Case for more information).
NOTE :
• If using the appropriate diagnostic test tool, you can diagnose the TCM harness while the TCM is still connected.
• Using the appropriate diagnostic test tool in this way will help prevent electrical connector terminal damage.
NOTE :
While performing electrical diagnosis & testing, always refer to the electrical schematics for specific circuit
and component information.
