Geely Emgrand X7. Manual part — 620

is under the
alarm state, the
vehicle

The anti-theft
horn does not
ring.

If it is confirmed that horn circuit is
normal after inspection, replace BCM.

See 11.8.8.1 Replacement of BCM.

Danger warning lamp circuit.

Be capable of opening the steering
lamp (hazard warning lamp). If all
steering lamps do not work, inspect
the steering lamp circuit.

When the
anti-theft system
is under the
alarm state, the
hazard alarm
lamp does not
flicker.

If all turning lamp doesn't work after
inspection, replace BCM.

If all steering lamps do not work,
replace BCM. Refer to 11.8.8.1

Diagnostic steps:

Notes:

Prior to the implementation of the diagnostic procedures, firstly make use of the fault diagnostic
unit, and then select body control system/BCM special set function/anti-theft indicator lamp in
sequence. Compel to turn on the anti-theft indicator lamp, which is conducive to quickly
troubleshoot.

1

Measure voltage between the alarm indicator harness connector IP14 terminal No.2.and
No.6.

(a)

Disconnect the anti-theft
indicator harness connector IP14.

(b)

Measure voltage between
terminal No.2 and No.6 with a
universal meter.

Standard voltage: 11-14 V

Confirm if the voltage conforms to
standard value
