General Check Before Troubleshooting

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

• Check the No. A2-3 (60 A) and No. A29 (10 A) fuses in the under-hood fuse/relay box.
• Check the No. B4 (15 A) and No. B31 (10 A) fuses in the under-dash fuse/relay box.
• Check for poor connection at the power control unit and the keyless access/TPMS 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 battery is fully charged.
• Make sure the keyless remote batteries are not low; if they are, replace the keyless remote battery.
• Make sure a different keyless remote is not being used; only use an Acura-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 or IGN TRX line; disconnect any aftermarket accessories from the S-NET or IGN TRX line.
