Test TC-50E: Trans 3-4 Solenoid/ Trans Relay Circuits
NOTE:
This test applies to AB body only. Perform TEST TC-50A: TRANS 3-4 SOLENOID/ TRANS RELAY CIRCUITS before proceeding. For connector terminal identification, see CONNECTOR IDENTIFICATION . For component location and for appropriate wiring diagram, see WIRING DIAGRAMS article.
- Using scan tool, read and record FREEZE FRAME data. Erase DTCs. Attempt to duplicate conditions in FREEZE FRAME data. Using scan tool, read DTCs. If DTC 3-4 SHIFT SOLENOID CIRCUIT resets, perform TEST TC-50A: TRANS 3-4 SOLENOID/ TRANS RELAY CIRCUITS . If DTC does not reset, go to next step.
- Condition required to set DTC is not present at this time. 3-4 SHIFT SOLENOID CIRCUIT DTC sets if voltage detected on 3-4 shift solenoid circuit at PCM is different than expected voltage. Possible causes are: defective transmission relay, open or shorted wiring to 3-4 shift solenoid, open fused ignition switch output circuit, defective connector terminals, or defective 3-4 shift solenoid. Go to next step.
- Inspect all related wiring and connectors. Repair wiring and connectors as necessary and perform TEST VER-5A: ROAD TEST FOR OBD-II TROUBLE CODES . If wiring and connectors are okay, go to next step.
- Using scan tool, erase DTCs. Using scan tool, actuate 3-4 shift solenoid and read DTCs while wiggling wiring harness from 3-4 shift solenoid to PCM and note if 3-4 SOLENOID DTC resets. If DTC resets, repair wiring harness as necessary and perform TEST VER-5A: ROAD TEST FOR OBD-II TROUBLE CODES . If DTC does not reset, see INACTIVE DTC CONDITION . Test is complete. Perform TEST VER-2A: ROAD TEST VERIFICATION .
NOTE:
A break in test sequence occurs at this point. Sequence skips from TEST TC-50E to TEST TC-55A. No tests have been omitted.
