Shift Lock System Circuit Troubleshooting (L15B7/L15BA/L15BY (CVT))
NOTE:
- Check for PGM-FI DTCs and CVT DTCs. If any DTCs are present, troubleshoot those first.
- There are two types of shift levers, Type A and B. Refer to the Shift Lever Removal and Installation for more details .

DTC (All DTCs)
- Shift lock solenoid operation check
-1. Connect the HDS to the DLC .
-2. Turn the vehicle to the ON mode.
-3. Select the Shift Lock Solenoid Test in the Miscellaneous Test Menu, and check that the shift lock solenoid operates with the HDS.
Shift Lock Solenoid Test
Does the shift lock solenoid work properly?
YES
The shift lock solenoid is OK. Go to step 6.
NO
Go to step 2.
- Fuse check
-1. Turn the vehicle to the OFF (LOCK) mode.
-2. Check the following fuse.
Fuse No. B7 Is the fuse OK?
YES
The fuse is OK. Reinstall the fuse, then go to step 3.
NO
Replace the No. B7 fuse, and recheck. If the fuse blows again, repair a short to ground in the No. B7 fuse circuit.
- Open wire check (IG1 METER line)
-1. Disconnect the following connector.
Park pin switch/shift lock solenoid 4P connector (Type A shift lever) Park pin switch/shift lock solenoid connector A (2P) (Type B shift lever) -2. Turn the vehicle to the ON mode.
-3. Measure the voltage between test points 1 and 2.
Test condition Vehicle ON mode Park pin switch/shift lock solenoid 4P connector: disconnected (Type A shift lever) Park pin switch/shift lock solenoid connector A (2P): disconnected (Type B shift lever) Test point 1 Park pin switch/shift lock solenoid 4P connector (female terminals) (Type A shift lever) No. 4: Park pin switch/shift lock solenoid connector A (2P) (female terminals) (Type B shift lever) No. 2: Test point 2 Body ground 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.
- Determine possible failure area (shift lock solenoid, others)
-1. With the transmission in P position/mode, press the brake pedal.
NOTE: Do not press the accelerator pedal.
-2. Measure the voltage between test points 1 and 2.
Test condition Vehicle ON mode Park pin switch/shift lock solenoid 4P connector: disconnected (Type A shift lever) Park pin switch/shift lock solenoid connector A (2P): disconnected (Type B shift lever) Test point 1 Park pin switch/shift lock solenoid 4P connector (female terminals) (Type A shift lever) No. 3: Park pin switch/shift lock solenoid connector A (2P) (female terminals) (Type B shift lever) No. 1: Test point 2 Park pin switch/shift lock solenoid 4P connector (female terminals) (Type A shift lever) No. 4: Park pin switch/shift lock solenoid connector A (2P) (female terminals) (Type B shift lever) No. 2: Is there battery voltage?
YES
Check the shift lock mechanism . If the mechanism is OK, replace the shift lock solenoid .
NO
Go to step 5.
- Open wire check (SLS/SHIFT LOCK SOL line)
-1. Turn the vehicle to the OFF (LOCK) mode.
-2. Disconnect the following connector.
TCM 50P connector -3. Check for continuity between test points 1 and 2.
Test condition Vehicle OFF (LOCK) mode Park pin switch/shift lock solenoid 4P connector: disconnected (Type A shift lever) Park pin switch/shift lock solenoid connector A (2P): disconnected (Type B shift lever) TCM 50P connector: disconnected Test point 1 Park pin switch/shift lock solenoid 4P connector (female terminals) (Type A shift lever) No. 3: Park pin switch/shift lock solenoid connector A (2P) (female terminals) (Type B shift lever) No. 1: Test point 2 TCM 50P connector No. 26 Is there 1.0 Ω or less?
YES
The SLS/SHIFT LOCK SOL wire is OK. Check for any authorized service information related to the DTCs or symptoms you are troubleshooting, or substitute a known-good TCM , then recheck. If the symptom goes away and the TCM was substituted, replace the original TCM .
NO
Repair an open in the SLS/SHIFT LOCK SOL wire between the shift lock solenoid and the TCM.
- Brake pedal position switch operation check
-1. Check the parameter(s) below with the HDS while pressing the brake pedal.
Signal Threshold Current conditions Values Unit Values Unit Brake Switch ON Do the current condition(s) match the threshold?
YES
The brake pedal position switch is OK. Go to step 8.
NO
If the brake lights come on, go to step 7. If the brake lights do not work, repair faulty brake light circuit.
- Open wire check (STOP SW line)
-1. Turn the vehicle to the OFF (LOCK) mode.
-2. Jump the SCS line with the HDS, and wait more than 1 minute.
-3. Disconnect the following connector.
PCM connector A (50P) -4. Measure the voltage between test points 1 and 2.
Test condition Vehicle OFF (LOCK) mode PCM connector A (50P): disconnected Test point 1 PCM connector A (50P) No. 26 Test point 2 Body ground Is there battery voltage while pressing the brake pedal and about 0 V when the pedal is released?
YES
The STOP SW wire is OK. Check for any authorized service information related to the DTCs or symptoms you are troubleshooting, or substitute a known-good PCM , then recheck. If the symptom goes away and the PCM was substituted, replace the original PCM .
NO
Repair an open in the STOP SW wire between the PCM and the brake pedal position switch.
- Transmission range switch parameter check
-1. Shift the transmission to P position/mode.
-2. Check the parameter(s) below with the HDS.
Signal Threshold Current conditions Values Unit Values Unit A/T P Switch ON Do the current condition(s) match the threshold?
YES
The transmission range switch is OK. Check for any authorized service information related to the DTCs or symptoms you are troubleshooting, or substitute a known-good TCM , then recheck. If the symptom goes away and the TCM was substituted, replace the original TCM .
NO
Go to step 9.
- Transmission range switch check
-1. Turn the vehicle to the OFF (LOCK) mode.
-2. Disconnect the following connector.
Transmission range switch 10P connector -3. Connect terminals A and B with a jumper wire.
Terminal A Transmission range switch 10P connector (female terminals) No. 5: Terminal B Body ground -4. Turn the vehicle to the ON mode.
-5. Check the parameter(s) below.
Signal Threshold Current conditions Values Unit Values Unit A/T P Switch ON Do the current condition(s) match the threshold?
YES
Replace the transmission range switch .
NO
The transmission range switch is OK. Go to step 10.
- Open wire check (ATP-P line)
-1. Turn the vehicle to the OFF (LOCK) mode.
-2. Remove the jumper wire.
-3. Disconnect the following connector.
TCM 50P connector -4. Check for continuity between test points 1 and 2.
Test condition Vehicle OFF (LOCK) mode Transmission range switch 10P connector: disconnected TCM 50P connector: disconnected Test point 1 Transmission range switch 10P connector (female terminals) No. 5: Test point 2 TCM 50P connector No. 48 Is there 1.0 Ω or less?
YES
The ATP-P wire is OK. Check for any authorized service information related to the DTCs or symptoms you are troubleshooting, or substitute a known-good TCM , then recheck. If the symptom goes away and the TCM was substituted, replace the original TCM .
NO
Repair an open in the ATP-P wire between the transmission range switch and the TCM.
