D3 Switch Circuit Troubleshooting
D3 Switch Circuit Troubleshooting1. Turn the ignition switch OFF.
2. Remove the shift lever, and disconnect the D3 switch/shift lock solenoid/park pin switch connector.
3. Check for continuity between D3 switch/shift lock solenoid/park pin switch connector terminals No. 3 and No. 4 while pressing the D3 switch and when the switch is released.
Is there continuity while pressing the D3 switch, and no continuity when the switch is released?
YES - Go to step 4.
NO - Replace the D3 switch.
4. Turn the ignition switch ON (II).
5. Shift to the D position.
6. Measure the voltage between D3 switch/shift lock solenoid/park pin switch connector terminal No. 4 and body ground.
Is there battery voltage?
YES - Repair an open in the wire between D3 switch/shift lock solenoid/park pin switch connector terminal No. 3 and ground (G401), or repair poor ground (G401).
NO - Go to step 7.
7. Turn the ignition switch OFF.
8. Jump the SCS line with the HDS.
9. Disconnect PCM connector A (44P).
10. Check for continuity between D3 switch/shift lock solenoid/park pin switch connector terminal No. 4 and body ground.
Is there continuity?
YES - Repair a short in the wire between PCM connector terminal A13 and D3 switch/shift lock solenoid/park pin switch connector.
NO - Go to step 11.
11. Check for continuity between D3 switch/shift lock solenoid/park pin switch connector terminal No. 4 and PCM connector terminal A13.
Is there continuity?
YES - Check for loose terminal fit in the PCM connectors, If necessary, substitute a known-good PCM and recheck.
NO - Repair an open in the wire between PCM connector terminal A13 and D3 switch/shift lock solenoid/park pin switch connector.
