Honda HR-V: Immobilizer System Symptom Troubleshooting Information

General Check Before Troubleshooting

Before troubleshooting the immobilizer system, check the following general items and resolve any issues, if applicable:

• The 12 volt battery is low; charge the 12 volt battery fully, then troubleshoot the immobilizer system.
• The ignition key is not a genuine Honda part; use a Honda-approved key blank, register the key, then troubleshoot the immobilizer system.
• If a key ring or a key case is used; remove the key from it, and troubleshoot the immobilizer system with the key only.
• An aftermarket electrical part is installed; remove it, then troubleshoot the immobilizer system.

Symptom Troubleshooting Using the Immobilizer Indicator Lighting Pattern

The pattern of the immobilizer indicator can help troubleshoot the condition of the immobilizer system. Here are descriptions of the four possible patterns:

Normal operation

If the immobilizer code is identified, the immobilizer indicator quickly flashes once when the vehicle is turned to the ON mode.

The immobilizer indicator does not come on when the vehicle is turned to the OFF (LOCK) mode.

Immobilizer code is not identified

If the immobilizer code is not identified, the immobilizer indicator will quickly flash once, then will blink until the vehicle is turned to the OFF (LOCK) mode. When the vehicle is turned to the OFF (LOCK) mode, the indicator will blink ten times, then go OFF to show the system is correctly reset.

The state of the immobilizer key registration and the S-NET line can be checked by doing a SYSTEM CHECK with the HDS.

Immobilizer indicator does not come on

If the immobilizer indicator does not come on after turning the vehicle is turned to the ON mode, there is an open or short in the F-CAN lines between the PCM and the gauge control module. Watch the malfunction indicator lamp (MIL). If the MIL stays on, go to PGM-FI system troubleshooting - Refer to: Fuel and Emissions Systems DTC Troubleshooting Index (KA/KC), or CVT System DTC Troubleshooting Index (KA/KC CVT).

Immobilizer indicator does not go off

If the immobilizer indicator does not go off after turning the vehicle is turned to the ON mode, do the gauge control module self-diagnostic function. If the indicator drive circuit is OK, do the SYSTEM CHECK with the HDS.

Symptom Troubleshooting Using Malfunctioning Circuit Functions

If a malfunction occurs in the immobilizer circuit, use the table to cross-reference the malfunction criteria to the line(s) that should be checked in the table:

System Check

NOTE: The HDS can be used to check the state of the immobilizer key registration and the S-NET line by doing a SYSTEM CHECK.

1. Connect the HDS to the data link connector (DLC).

NOTE: If the HDS does not communicate with the vehicle, go to the DLC Circuit Troubleshooting.

2. The vehicle is turned to the ON mode and follow the prompts to the SYSTEM SELECTION MENU.

3. At SYSTEM SELECTION MENU, enter IMMOBI, then select the IMMOBILIZER SETUP.

4. Do the SYSTEM CHECK. If there is a system check number, do the troubleshooting for the item indicated.
