Test G: 3-2T/CCS Solenoid
WARNING: This page is about a different variant/trim than selected.
- Electronic Diagnostics
Ensure transaxle harness connector is in acceptable condition. Repair as necessary. Ensure transaxle harness connector is fully seated. Connect NGS tester or equivalent to DLC. Perform KOEO self-test until continuous memory codes have been displayed. See QUICK TEST under DIAGNOSIS & TESTING. Enter output test mode. See ADDITIONAL SYSTEM FUNCTIONS under DIAGNOSIS & TESTING. Select ALL ON mode. Push START to turn outputs on. Push STOP to turn outputs off. If vehicle enters output test mode, go to next step. If vehicle will not enter output test mode, see SCAN TOOL UNABLE TO COMMUNICATE under DIAGNOSIS & TESTING. - Check Electrical Signal Operation
Turn ignition off. Disconnect transaxle harness connector. Inspect condition of connector and repair as necessary. Turn ignition on. Using DVOM, connect positive lead to transaxle harness connector terminal No. 5 and negative lead to terminal No. 10. See Figure. While monitoring DVOM, press START and STOP to cycle solenoid output on and off. If voltage changes at least .5 volt, go to step 5. If voltage does not change, go to next step. - Check Continuity Of Solenoid Signal And VPWR Circuit
Turn ignition off, and wait 10 seconds. Disconnect PCM 104-pin connector, and inspect for damaged terminals, corrosion and loose wires. Repair as necessary. Install breakout box, leaving PCM disconnected. Measure and record resistance between breakout box test pins No. 71 and 97, and transaxle harness connector terminal No. 5. See Figure. Measure and record resistance between breakout box test pins No. 102 and transaxle harness connector terminal No. 10. If each resistance reading is 5 ohms or less, go to next step. If any resistance reading is more than 5 ohms, repair open circuit. See WIRING DIAGRAMS . Connect all components. Clear DTCs. See CLEARING DIAGNOSTIC TROUBLE CODES under DIAGNOSIS & TESTING. Repeat QUICK TEST under DIAGNOSIS & TESTING. - Check Harness For Short To Power Or Ground
Measure and record resistance between breakout box test pin No. 102 and test pins No. 71 and 97. Measure and record resistance between breakout box test pin No. 102 and test pins No. 24, 51, 77, 91 and 103. If any resistance reading is less than 10 k/ohms, repair short circuit. See WIRING DIAGRAMS . Disconnect breakout box and repeat QUICK TEST under DIAGNOSIS & TESTING. If each resistance reading is 10 k/ohms or more, go to next step. - Transaxle Functional Test
Connect PCM 104-pin connector. Disconnect transaxle harness connector. Connect transaxle tester. Set Bench/Drive switch to DRIVE position. Set gear selector switch to "1" position. Perform 3-2T/CCS solenoid function test. See tester instructions. 3-2T/CCS solenoid should engage (LED off) and engine braking should occur when switch is released. If solenoid operates correctly, replace PCM. Connect all components. Clear DTCs. See CLEARING DIAGNOSTIC TROUBLE CODES under DIAGNOSIS & TESTING. Repeat QUICK TEST under DIAGNOSIS & TESTING. If solenoid is not operating, go to next step. - Transaxle Drive Cycle Test
Ensure tester power is off. Connect ohmmeter to 3-2T/CCS solenoid jacks. If resistance is 3.75-5.92 ohms, go to next step. If resistance is not 3.75-5.92 ohms, replace solenoid body assembly. See FORD CD4E (MAZDA LA4A-EL) OVERHAUL article. Connect all components. Clear DTCs. See CLEARING DIAGNOSTIC TROUBLE CODES under DIAGNOSIS & TESTING. Repeat QUICK TEST under DIAGNOSIS & TESTING. - Check Resistance Of Solenoid
Check continuity between BAT(-) jack of transmission tester and 3-2T/CCS solenoid jacks. If continuity exists, replace solenoid body assembly. See FORD CD4E (MAZDA LA4A-EL) OVERHAUL article. Connect all components. Clear DTCs. See CLEARING DIAGNOSTIC TROUBLE CODES under DIAGNOSIS & TESTING. Repeat QUICK TEST under DIAGNOSIS & TESTING. If continuity does not exist, see SYMPTOM DIAGNOSIS under TROUBLE SHOOTING in FORD CD4E (MAZDA LA4A-EL) OVERHAUL article.
