KEYLESS RECEIVER INSPECTION

id091400701900

1. Disconnect the negative lead-acid battery terminal. (See NEGATIVE LEAD-ACID BATTERY TERMINAL DISCONNECTION/CONNECTION.)

2. Remove the keyless receiver with the connector still connected. (See KEYLESS RECEIVER REMOVAL/INSTALLATION.)

3. Connect the negative lead-acid battery terminal. (See NEGATIVE LEAD-ACID BATTERY TERMINAL DISCONNECTION/CONNECTION.)

4. Verify that the voltages of each of the terminals are as indicated in the terminal voltage table (See Terminal Voltage Table (Reference)).

• If the voltage is not as specified in the terminal voltage table (See Terminal Voltage Table (Reference)), inspect the parts under Inspection item(s) and related wiring harnesses.

― If the system does not operate normally even though the parts under Inspection Item(s) and related wiring harnesses do not have any malfunction, replace the keyless receiver. (See KEYLESS RECEIVER REMOVAL/INSTALLATION.)
