Diagnostic Information and Procedures

Cruise Control System Symptom Diagnosis

S5JB0EA104001

NOTE

• ECM uses TCM, ABS or ESP

® control module and CAN communication to transmit and receive data 

for cruise control. Therefore, check that no DTC is detected from ECM, TCM, ABS or ESP

® control 

module before performing this Cruise Control System Symptom Diagnosis. If DTC is detected, 
correct trouble indicated by that DTC first.

• Check each part in the order from the top of the following list.

Precautions

Precautions in Diagnosing Trouble

S5JB0EA200001

• Diagnostic information stored in BCM memory can be cleared as well as checked by using SUZUKI scan tool. 

Before using scan tool, read its Operator’s (Instruction) Manual carefully to have good understanding as to what 
functions are available and how to use it.

• Be sure to read “Precautions for Electrical Circuit Service in Section 00 in related manual” before inspection and 

observe what is written there.

• Communication of ECM, TCM (if equipped), BCM, ABS or ESP

® control module (if equipped), 4WD control module 

(if equipped), keyless start control module (if equipped), steering angle sensor (if equipped) and combination meter 
is established by CAN (Controller Area Network).
Therefore, be sure to read “Precaution for CAN Communication System in Section 00 in related manual” before 
inspection and handle CAN communication line.

General Description

BCM General Description

S5JB0EA201001

The BCM incorporates relays and controllers which are used for the following systems and controls them.
• Power door lock (if equipped)
• Keyless entry (if equipped)
• Door lock function of keyless start system (if equipped)
• Rear wiper
• Combination meter
• Interior light / luggage room light
• Warning buzzer
• Rear end door window defogger and door mirror heater (if equipped)
• DRL (if equipped)
• Auto-on headlight (if equipped)
• Front fog light (if equipped)
• Theft deterrent light
Also, the BCM has a function to cause the interior light and open door warning lamp in the combination meter to turn 
off when any door is left open for longer than 15 minutes to reduce wasteful battery consumption.
In addition, it is possible to check operation of actuator which is controlled by BCM by using the output test function of 
SUZUKI scan tool to operate actuator simulatively.
