FUEL SYSTEM (DFI) 3-85

Immobilizer Amplifier (Service Code 35 (Equipped Models))

Antenna Resistance Inspection

•Turn the ignition switch OFF.

•Remove the air cleaner housing (see Air Cleaner Housing Removal).

•Disconnect the antenna lead connector [A].

•Measure the antenna resistance.

Antenna Resistance

Connections: BK lead ←→ BK lead

Standard: About 0.6 0.9 Ω

If the reading is out of the standard, replace the antenna (see Immobilizer System Parts Replacement in the Electrical System chapter).

If the reading is within the standard, check the wiring to the amplifier (see wiring diagram in next section).

If the wiring is good, check the input voltage of the amplifier (see Amplifier Input Voltage Inspection).

Amplifier Input Voltage Inspection

NOTE

○Be sure the battery is fully charged.

•Turn the ignition switch OFF.

•Remove the upper fairing assembly (see Upper Fairing Assembly Removal in the Frame chapter).

•Pull out the immobilizer amplifier [A] with the rubber protector [B] from the projections [C].

•Connect a digital meter to the amplifier connector [D] with needle adapter set.

Special Tool - Needle Adapter Set: 57001-1457

Amplifier Input Voltage

Connections to Amplifier Connector: Digital Meter (+) → BR/W lead Digital Meter (–) → BK/Y lead

•Measure the input voltage with the engine stopped and with the connector joined.

•Turn the ignition switch ON.

Input Voltage

Standard: Battery Voltage

•Turn the ignition switch OFF.

If the reading is out of the standard, check the wiring (see wiring diagram in next section).

Special Tool - Hand Tester: 57001-1394

If the reading is within the standard, check the wiring to

ECU (see wiring diagram in next section).
