E5 TRANSAXLE FUNCTIONAL TEST
• Solenoid body connector disconnected.
• Install transaxle tester.
• Set bench/drive switch to drive mode.
• Rotate gear selector switch to first gear
position.
• Using tests outlined in the manual perform the
EPC function test.
• Observe line pressure on the gauge while
depressing the EPC switch. (VEHICLE MUST
BE RUNNING)
• Does the EPC (LED GREEN) activate and line
pressure drop when the EPC switch is
depressed?
Yes Replace PCM.
Rerun OBD test.
No Go to next step.
E6
CHECK RESISTANCE OF SOLENOID
Note
• Be sure that tester power is OFF or damage to
ohmmeter may result.
• Connect ohmmeter negative lead to VPWR
jack and positive lead to EPC jack on tester.
This is to test EPC solenoid.
• Record resistance.
• Is the resistance between 3.75— 5.92 ohms?
Yes Go to next step.
No Replace solenoid body component.
Record and erase DTCs.
Rerun OBD test.
E7 CHECK SOLENOID FOR SHORT TO GROUND
• Check for continuity between B A T - (engine
ground) and appropriate jack with an
ohmmeter or other low current tester (less than
