D3 Switch Circuit Troubleshooting
D3 Switch Circuit Troubleshooting1. Remove the shift lever.
2. Turn the ignition switch to ON (II).
3. Measure the voltage between D3 switch/park pin switch/A/T gear position indicator panel light connector terminals No. 5 and No. 6.
Is there about 5 V?
Yes - Go to step 10.
No - Go to step 4.
4. Measure the voltage between D3 switch/park pin switch/A/T gear position indicator panel light connector terminal No. 5 and body ground.
Is there about 5 V?
Yes - Repair open in the wire between D3 switch/park pin switch/A/T gear position indicator panel light connector terminal No. 6 and ground (G503), and repair poor ground (G503).
No - Go to step 5.
5. Turn the ignition switch to LOCK (0).
6. Jump the SCS line with the HDS.
7. Disconnect PCM connector A (44P).
8. Check for continuity between PCM connector terminal A41 and D3 switch/park pin switch/A/T gear position indicator panel light connector terminal No. 5.
Is there continuity?
Yes - Go to step 9.
No - Repair open in the wire between PCM connector terminal A41 and the D3 switch/park pin switch/A/T gear position indicator panel light connector.
9. Check for continuity between D3 switch/park pin switch/A/T gear position indicator panel light connector terminal No. 5 and body ground.
Is there continuity?
Yes - Repair short in the wire between PCM connector terminal A41 and the D3 switch/park pin switch/A/T gear position indicator panel light connector.
No - Check for loose or poor connection at PCM connector terminal A41. If the connection is OK, substitute a known-good PCM and recheck. If the symptom goes away with a known-good PCM, replace the original PCM.
10. Check for continuity between D3 switch/park pin switch/A/T gear position indicator panel light connector terminals No. 5 and No. 6 while pressing the D3 switch several times.
Is there alternating continuity and no continuity every time the switch is pushed?
Yes - Check for loose or poor connection at PCM connector terminal A41. If the connection is OK, substitute a known-good PCM and recheck. If the symptom goes away with a known-good PCM, replace the original PCM.
No - Replace the D3 switch.
