INSPECT KEYLESS ANTENNA (INTERIOR, FRONT) CONNECTOR CONDITION
- Switch the ignition off.
- Disconnect the negative battery terminal. (See NEGATIVE BATTERY TERMINAL DISCONNECTION/CONNECTION
.)
- Disconnect the keyless antenna (interior, front) connector.
- Inspect the connector engagement and connection condition and inspect the terminals for damage, deformation, corrosion, or disconnection.
- Is the connector normal?
|
Yes |
Go to the next step. |
| No |
Repair or replace the connector, then go to Step 7. |
| 2 |
INSPECT LF CONTROL UNIT CONNECTOR CONDITION
- Disconnect the LF control unit connector.
- Inspect the connector engagement and connection condition and inspect the terminals for damage, deformation, corrosion, or disconnection.
- Is the connector normal?
|
Yes |
Go to the next step. |
| No |
Repair or replace the connector, then go to Step 7. |
| 3 |
INSPECT KEYLESS ANTENNA (INTERIOR, FRONT) CIRCUIT FOR SHORT TO GROUND
- Verify that the LF control unit and keyless antenna (interior, front) connectors are disconnected.
- Inspect for continuity between the following terminals (wiring harness-side) and body ground:
- Keyless antenna (interior, front) terminal B
- Keyless antenna (interior, front) terminal A
- Is there continuity?
|
Yes |
Refer to the wiring diagram and verify whether or not there is a common connector between the following terminals:
- LF control unit terminal K-Keyless antenna (interior, front) terminal B
- LF control unit terminal M-Keyless antenna (interior, front) terminal A
If there is a common connector:
- Determine the malfunctioning part by inspecting the common connector and the terminal for corrosion, damage, or pin disconnection, and the common wiring harness for a short to ground.
- Repair or replace the malfunctioning part.
If there is no common connector:
- Repair or replace the wiring harness which has a short to ground.
Go to Step 7. |
| No |
Go to the next step. |
| 4 |
INSPECT KEYLESS ANTENNA (INTERIOR, FRONT) CIRCUIT FOR OPEN CIRCUIT
- Verify that the LF control unit and keyless antenna (interior, front) connectors are disconnected.
- Inspect for continuity between the following terminals (wiring harness-side):
- LF control unit terminal K-Keyless antenna (interior, front) terminal B
- LF control unit terminal M-Keyless antenna (interior, front) terminal A
- Is there continuity?
|
Yes |
Go to the next step. |
| No |
Refer to the wiring diagram and verify whether or not there is a common connector between the following terminals:
- LF control unit terminal K-Keyless antenna (interior, front) terminal B
- LF control unit terminal M-Keyless antenna (interior, front) terminal A
If there is a common connector:
- Determine the malfunctioning part by inspecting the common connector and the terminal for corrosion, damage, or pin disconnection, and the common wiring harness for an open circuit.
- Repair or replace the malfunctioning part.
If there is no common connector:
- Repair or replace the wiring harness which has an open circuit.
Go to Step 7. |
| 5 |
INSPECT LF CONTROL UNIT
|
Yes |
Go to the next step. |
| No |
Replace the LF control unit, then go to Step 7. (See LF CONTROL UNIT REMOVAL/INSTALLATION
.) |
| 6 |
VERIFY IF MALFUNCTIONING LOCATION IS KEYLESS ANTENNA (INTERIOR, FRONT) DEPENDING ON REPEATABILITY
|
Yes |
Replace the keyless antenna (interior, front), then go to the next step. (See KEYLESS ANTENNA REMOVAL/INSTALLATION
.) |
| No |
Go to Step 8. |
| 7 |
VERIFY THAT REPAIRS HAVE BEEN COMPLETED
|
Yes |
Repeat the inspection from Step 1.
|
| No |
Go to the next step. |
| 8 |
VERIFY IF OTHER DTCs DISPLAYED
- Are any other DTCs displayed?
|
Yes |
Repair or replace the malfunctioning part according to the applicable DTC troubleshooting. (See DTC TABLE [START STOP UNIT] .) |
| No |
DTC troubleshooting completed. |
