Honda HR-V: Keyless Access System Symptom Troubleshooting Information

General Check Before Troubleshooting

Before troubleshooting the keyless access system, check the following items and solve any applicable issues.

• Check the No. A1 (100 A) and No. A2 (70 A) fuses in the 12 volt battery terminal fuse box.
• Check the No. B21 (10 A) fuse in the under-hood fuse/relay box.
• Check the No. C32 (15 A) and C3 (10 A) fuses in the under-dash fuse/relay box.
• Check the No. D1-3 (50 A) fuse in the auxiliary under-dash fuse box A.
• Check for poor connection at the keyless access control unit.
• Check for DTCs with the HDS; if a DTC is indicated, troubleshoot the DTC first.
• Before testing, troubleshoot the keyless access system first using SELF CHECK, and if any malfunction is found, troubleshoot it first.
• Make sure the keyless remote is not in a purse with coins, wrapped with any metallic material, placed near a mobile phone or computer.
• Make sure the vehicle 12 volt battery is fully charged.
• Make sure the keyless remote batteries are not low; if they are, replace the battery.
• Make sure a different keyless remote is not being used; only use a Honda-approved keyless remote.
• Make sure the keyless remote is not attached to a key ring or key case; if it is, remove the key from it.
• Make sure aftermarket accessories are not installed; remove any aftermarket accessories.
• Make sure aftermarket accessories are not connected to the S-NET line; disconnect any aftermarket accessories from the S-NET line.
• Make sure there is no electrical interference nearby; avoid areas with electrical interference.

Symptom Troubleshooting Using the Immobilizer Indicator Lighting Pattern

The immobilizer and keyless access system condition can be checked by the immobilizer indicator lighting pattern.

Normal operation:

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

Immobilizer code is not identified:

When the vehicle is turned to the ON mode when the immobilizer code has not been identified, the immobilizer indicator will come on for 2 seconds, then blink until the OFF mode is selected. The state of keyless registration and the S-NET line can be checked by doing a system check and a status log check with the HDS.

When the vehicle is turned to the OFF (LOCK) mode, the immobilizer indicator will blink 10 times to signal that until it has been reset correctly, the immobilizer indicator will remain off.

Immobilizer indicator does not come on:

If the immobilizer indicator does not come on after 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 the vehicle is turned to the ON mode, do the gauge control module self-diagnostic function procedures. If the indicator drive circuit is OK, do the SYSTEM CHECK and STATUS LOG procedures with the HDS.

System Check and Status Log

NOTE: The HDS can be used to:

• Check the state of the keyless remote registration and the S-NET line by doing a SYSTEM CHECK.
• Check the number of times the keyless access control unit or the backup control unit did not permitted the engine to start by checking the STATUS LOG.

1. Connect the HDS to the data link connector (DLC), then the vehicle is turned to the ON mode and follow the prompts to the SYSTEM SELECTION MENU.

NOTE: If the HDS does not communicate with the vehicle, go to the DLC circuit troubleshooting.

2. At SYSTEM SELECTION MENU, enter ONE-PUSH START, then select KEYLESS ACCESS CONTROL UNIT or BACKUP CONTROL UNIT.

3. At KEYLESS ACCESS CONTROL UNIT, enter KEYLESS ACCESS SYSTEM INFORMATION, then select SYSTEM CHECK 1, 2.

4. At BACKUP CONTROL UNIT, enter SYSTEM INFORMATION, then select SYSTEM CHECK.

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

6. Check the STATUS LOG using the HDS. Troubleshoot the line with the highest counts first. If all the lines are 0 (zero), the problem may not be caused by the immobilizer system within the keyless access system, check for ignition or fuel problems.

NOTE: Once repaired, clear the status log by removing the No. B21 (10 A) fuse in the under-hood fuse/relay box or disconnecting the 12 volt battery.

KEYLESS/POWER DOOR LOCKS/SECURITY SYSTEM TRIPPED SENSOR RECALL

The security system stores information on the last tripped sensor if the security system has been actuated. The information can be retrieved using the HDS.

To retrieve the last tripped sensor data, do this:

1. Select HISTORY DATA from the SECURITY MODE MENU

2. Scroll through the data list.

• Sensors that were actuated will indicate DETECT.
• Sensors that were not actuated will indicate NONE.

3. Inspect the DETECT circuit for:

• Misadjusted or damaged switch.
• Loose or corroded connections.
• Intermittent short to ground.

NOTE: If PANIC FRAME RECEPTION is indicated ON, inform the customer that it could have been set by something pressing the panic button of one of the registered remotes (in a pocket or purse, under a stack of papers, etc.).
