.
- Using scan tool, retrieve freeze data. Clear DTCs and road test vehicle under same conditions freeze data was recorded. If DTC resets, go to next step. If DTC does not reset, problem is intermittent, check transaxle and PCM connections.
- Turn ignition off. Disconnect PCM harness connectors "B" and "D". Turn ignition on. Measure voltage between PCM harness connector "D" terminal No. 2 (Green/White wire) and connector "B" terminal No. 20 or 22 (Brown/Black wires). If voltage is not present, go to next step. If voltage is present, repair short to voltage in Green/White wire between PCM harness connector "D" and shift control solenoid valve "B".
- Turn ignition off. Measure resistance of shift control solenoid valve "A" between PCM harness connector "D" terminal No. 2 (Green/White wire) and connector "B" terminal No. 20 or 22 (Brown/Black wires). If resistance is not 12-25 ohms, go to next step. If resistance is 12-25 ohms, go to step 7.
- Check for continuity between PCM harness connector "B" terminal No. 20 and ground, and between terminal No. 22 and ground. If continuity is present, go to next step. If continuity is not present, repair open in appropriate Brown/Black wire between PCM harness connector "B" and ground.
- Disconnect shift control solenoid valve "A"/"B" harness connector. Check for continuity between PCM harness connector "D" terminal No. 2 (Green/White wire) and connector "B" terminal No. 20 or 22 (Brown/Black wires). If continuity is not present, go to next step. If continuity is present, repair short to ground in Green/White wire between PCM harness connector "D" and shift control solenoid valve "B".
- Measure resistance between shift control solenoid valve "A"/"B" harness connector (solenoid side) Green/White wire and ground. If resistance is not 12-25 ohms, replace shift control solenoid valve "A"/"B" assembly. See SHIFT CONTROL SOLENOID VALVE "A"/"B" ASSEMBLY under REMOVAL & INSTALLATION. If resistance is 12-25 ohms, repair open in Green/White wire between PCM harness connector "D" and shift control solenoid valve "B".
- Turn ignition on. Measure voltage between PCM harness connector "D" terminal No. 5 (Black/Yellow wire) and connector "B" terminal No. 20 or 22 (Brown/Black wires). If battery voltage is present, check for loose PCM harness connectors. If connectors are okay, substitute a known-good PCM and retest. If battery voltage is not present, check fuse No. 15 (7.5-amp) in underdash fuse/relay box. If fuse is okay, repair open in Black/Yellow wire between PCM connector "D" and underdash fuse/relay box.
