Electric Load Current Sensor On-Vehicle Inspection (For J20 Engine); Electric Load Current Sensor Removal And Installation (For J20 Engine) - Suzuki Grand Vitara 2011 Manual

Electric Load Current Sensor On-Vehicle
Inspection (For J20 Engine)
Using SUZUKI Scan Tool
1) Connect scan tool to DLC with ignition switch turned
OFF.
2) Check "Battery Current" displayed on scan tool at
following condition.
Battery current
Ignition switch ON: 5.0 – 6.0 A
Run engine at 2000 rpm, headlight ON: 19.0 – 23.0 A
Run engine at 2000 rpm, headlight ON and blower
motor switch is HI position: 37.0 – 42.0 A
If check result is satisfactory, electric load current sensor
is in good condition.
If check result is not satisfactory, check the following
parts and circuit.
• Electric load current sensor circuit (power, ground and
output)
• Following charging system components
– Battery (refer to "Battery Inspection: For Petrol
Engine Model in Section 1J")
– Generator (refer to "Generator Inspection: For
Petrol Engine Model in Section 1J")
– Generator output control circuit (refer to "Generator
Test (Undercharged Battery Check): For Petrol
Engine Model in Section 1J")
– Generator field coil monitor circuit (refer to
"Generator Inspection: For Petrol Engine Model in
Section 1J")
If electric load current sensor circuit and charging
system is in good condition, electric load current sensor
is faulty.
Engine Electrical Devices: For Petrol Engine Model 1C-19
Without Using SUZUKI Scan Tool
1) Measure sensor voltage between "C37-9" terminal of
S6JB0A1316023
ECM connector and vehicle body ground referring to
"Inspection of ECM and Its Circuits: For Petrol
Engine Model in Section 1A".
If check result is satisfactory, electric load current
sensor is in good condition.
If check result is not satisfactory, check the following
parts and circuit.
• Electric load current sensor circuit (power, ground
and output)
• Following charging system components
– Battery (refer to "Battery Inspection: For Petrol
– Generator (refer to "Generator Inspection: For
– Generator output control circuit (refer to
– Generator field coil monitor circuit (refer to
If electric load current sensor circuit and charging
system is in good condition, electric load current
sensor is faulty.
