1. Shift lock solenoid check:
Shift Lock Solenoid Test
Does the shift lock solenoid work properly?
YES
The shift lock solenoid is OK. Go to step 7.
NO
Go to step 2.
2. Fuse check:
Is the fuse OK?
YES
The fuse is OK. Go to step 3.
NO
Replace the No. C34 (7.5 A) fuse, and recheck. If the fuse blows again, repair a short to ground in the No. C34 (7.5 A) fuse circuit.
3. Open wire check (IG1 METER line):
Shift lock solenoid 2P connector
Is there battery voltage?
YES
The IG1 METER wire is OK. Go to step 4.
NO
Repair an open in the IG1 METER wire between the shift lock solenoid and the under-dash fuse/relay box.
4. Determine possible failure area (short in SHIFT LOCK SOL line, open in SHIFT LOCK SOL line):
NOTE: Do not press the accelerator pedal.
Is there battery voltage?
YES
Go to step 5.
NO
Go to step 6.
5. Shorted wire check (SHIFT LOCK SOL line):
NOTE: The shift lever must be in P position/mode.
Is there battery voltage?
YES
Repair a short to ground in the SHIFT LOCK SOL wire between the shift lock solenoid and the PCM.
NO
The SHIFT LOCK SOL wire is OK. Check the shift lock mechanism. If the mechanism is OK, replace the shift lock solenoid.
6. Open wire check (SHIFT LOCK SOL line):
PCM connector A (51P)
Is there continuity?
YES
The SHIFT LOCK SOL wire is OK. Update the PCM if it does not have the latest software, or substitute a known-good PCM, then recheck. If the symptom goes away and the PCM was updated, troubleshooting is complete. If the symptom goes away and the PCM was substituted, replace the original PCM.
NO
Repair an open in the SHIFT LOCK SOL wire between the shift lock solenoid and the PCM.
7. Brake pedal position switch check:
Check the parameter(s) below with the HDS while pressing the brake pedal.
Do the current condition (s) match the threshold?
YES
The brake pedal position switch is OK. Go to step 9.
NO
If the brake lights come on, go to step 8. If the brake lights do not work, repair faulty brake light circuit.
8. Open wire check (BRK DIAG line):
PCM connector A (51P)
Is there battery voltage while pressing the brake pedal, and about 0 V when the pedal is released?
YES
The BRK DIAG wire is OK. Update the PCM if it does not have the latest software, or substitute a known-good PCM, then recheck. If the symptom goes away and the PCM was updated, troubleshooting is complete. If the symptom goes away and the PCM was substituted, replace the original PCM.
NO
Repair an open in the BRK DIAG wire between the brake pedal position switch and the PCM.
9. Transmission range switch operation check:
Check the parameter(s) below with the HDS with the shift lever in P position/mode.
Do the current condition (s) match the threshold?
YES
The transmission range switch is OK. Go to step 12.
NO
Go to step 10.
10. Transmission range switch check:
Transmission range switch 10P connector
Do the current condition (s) match the threshold?
YES
Replace the transmission range switch.
NO
The transmission range switch is OK. Go to step 11.
11. Open wire check (ATP P line):
PCM connector B (51P)
Is there continuity?
YES
The ATP P wire is OK. Update the PCM if it does not have the latest software, or substitute a known-good PCM, then recheck. If the symptom goes away and the PCM was updated, troubleshooting is complete. If the symptom goes away and the PCM was substituted, replace the original PCM.
NO
Repair an open in the ATP P wire between the transmission range switch and the PCM.
12. APP sensor check:
Check the parameter(s) below with the HDS.
NOTE: Do not press the accelerator pedal.
Do the current condition (s) match the threshold?
YES
The APP sensor is OK. Update the PCM if it does not have the latest software, or substitute a known-good PCM, then recheck. If the symptom goes away and the PCM was updated, troubleshooting is complete. If the symptom goes away and the PCM was substituted, replace the original PCM.
NO
Check the APP sensor.
