Geely Emgrand X7. Manual part — 498

(a) Disconnect the steering lamp harness connector
CA12.

(b) Measure the resistance between terminal 5 of
harness connector CA12 of turning light and
grounding.

Standard Resistance: Less than 1 Ω

(d) Measure the resistance between terminal 8 of
license lamp harness connector CA12 and grounding.

Standard Resistance: More than 10 Ω or higher

Confirm whether the resistance is at a specified value.

Replace the BCM

(a) Replace BCM and refer to Replacement of BCM in 11.8.8.1.

Confirm the completion of repair.

10.4 Programming and Setting

10.4.1 Programming and Setting

1. Cautions

in

compilation.

Prior to control module programming; ensure that the following conditions have been met:

A. Vehicle system voltage

a. The charging system should be free from malfunctions. The charge system failure must be

removed before programming the control module.

b. The accumulator voltage should be higher than 12V but lower than 16V. If the battery voltage is

too low, the battery must be charged prior to the control module programming.

c. The accumulator recharger must not be connected to the vehicle accumulator. An incorrect system

voltage or voltage fluctuation caused by the accumulator recharger will result in programming
failure or cause the control module to be damaged.

d. Turn off or disable all electrical loads of the vehicle accumulator, such as the following

components:

– Inside

lamp

–

Heating, venting and air condition (HVAC) system

–

Engine cooling fan and audios.

B. The ignition switch must be put in the correct position. Do not change the position of the ignition switch

in the programming process, unless the diagnostic unit is indicated.

C. Make sure all tools including the following components and circuits are connected securely:

a. Control module serial data link tester

b. Connection at DLC

c. Power

circuit

D. Do not disturb the tool harness during programming. An unexpected interruption of programming will

result in programming failure or control module damage.

2. Programming and setting after replacement of ECM.

After replacing the ECM, an anti-theft read-in program must be executed for the ECU; refer to

2.5.7.10

Programming after Replacing ECM

3. Programming and setting after replacement of ABS module.

The device needs not to program or set.

4. Programming and setting after replacement of combination instrument assembly.

The device needs not to program or set.

6. Programming and Setting after Replacement of BCM.

Remove anti-theft; and open the driver-side door. After carrying out IGN OFF / ON for three times within 8s,
IGN is placed in ON; after carrying out the driver-side door OPEN / CLOSE / OPEN once within 8s, the
driver-side door is placed in the OPEN; after carrying out IGN ON / OFF / ON once within 8s, IGN is placed in
ON; and if successfully enter the learning code mode, the horn sounds once. Simultaneously press the emitter
unlock key and lock key within 10s to enter into the system; if learning code successfully, the anti-theft horn
sounds twice; and if it is the first key with successful code learning in this learning process, wipe all previous
learned codes. If learning code fails, the anti-theft horn sounds four times. Repeat step 5 and step8, and then learn
the next remote control unit. Clean the previous ID after learninga the first key at every turn.
