Suzuki Grand Vitara JB627. Manual - part 25
1A-49 Engine General Information and Diagnosis:
LONG FT B1 (LONG TERM FUEL TRIM BANK-1, %)
LONG FT B2 (LONG TERM FUEL TRIM BANK-2, %)
Long term fuel trim value represents long term
corrections to the air/fuel mixture computation. A value
of 0 indicates no correction, a value greater than 0
means an enrichment correction, and a value less than 0
implies an enleanment correction.
TOTAL FUEL TRIM B1 (TOTAL FUEL TRIM BANK-1,
%) TOTAL FUEL TRIM B2 (TOTAL FUEL TRIM BANK-
2, %)
The value of Total Fuel Trim is obtained by calculating
based on values of Short Term Fuel Trim and Long Term
Fuel Trim. This value indicates how much correction is
necessary to keep the air/fuel mixture stoichiometrical.
A/F B1 S1 CURRENT (A/F SENSOR BANK-1
SENSOR-1 OUTPUT CURRENT, mA) A/F B2 S1
CURRENT (A/F SENSOR BANK-2 SENSOR-1
OUTPUT CURRENT, mA)
This parameter indicates output current of A/F sensor
installed on exhaust manifold (pre-catalyst).
FUEL CUT (ON / OFF)
ON: Fuel being cut (output signal to injector is stopped)
OFF: Fuel not being cut
O2S B1 S2 ACT (HEATED OXYGEN SENSOR BANK-
1 SENSOR-2, ACTIVE / INACTIVE) O2S B2 S2 ACT
(HEATED OXYGEN SENSOR BANK-2 SENSOR-2,
ACTIVE / INACTIVE)
This parameter indicates activation condition of HO2S-2
ACTIVE: Activating
INACTIVE: warming up or at stop.
A/F B1 S1 ACT (A/F SENSOR BANK-1 SENSOR-1,
ACTIVE / INACTIVE) A/F B2 S1 ACT (A/F SENSOR
BANK-2 SENSOR-1, ACTIVE / INACTIVE)
This parameter indicates activation condition of A/F
sensor
ACTIVE: Activating
INACTIVE: warming up or at stop
CANIST PRG DUTY (EVAP CANISTER PURGE FLOW
DUTY, %)
This parameter indicates valve ON (valve open) time
rate within a certain set cycle of EVAP canister purge
valve which controls the amount of EVAP purge.
IGNITION ADVANCE (IGNITION TIMING ADVANCE
FOR NO.1 CYLINDER,
°)
Ignition timing of No.1 cylinder is commanded by ECM.
The actual ignition timing should be checked by using
the timing light.
EGR VALVE OPENING (%)
This parameter indicates opening rate of EGR valve
which controls the amount of EGR flow.
FUEL PUMP (ON / OFF)
ON is displayed when ECM activates the fuel pump via
the fuel pump relay switch.
STARTER SW (ON / OFF)
This parameter indicates condition of starting motor relay
output.
ON: Starting motor relay is ON
OFF: Starting motor relay is OFF
A/C PRESSURE (A/C REFRIGERANT ABSOLUTE
PRESSURE, kPa)
This parameter indicates A/C refrigerant absolute
pressure calculated by ECM.
A/C SWITCH (ON / OFF)
ON: Command for A/C operation being output from ECM
to HVAC.
OFF: Command for A/C operation not being output.
A/C COMP RELAY (A/C COMPRESSOR RELAY, ON /
OFF)
This parameter indicates the state of the A/C switch.
BLOWER FAN (ON / OFF)
This parameter indicates the state of the blower fan
motor switch.
ELECTRIC LOAD (ON / OFF)
ON: Headlight, clearance light or rear defogger ON
signal inputted.
OFF: Above electric loads all turned OFF.
PSP SWITCH (POWER STEERING PUMP PRESSURE
SWITCH, ON / OFF)
ON: PSP SW is ON (P/S high pressure switch is ON)
OFF: PSP SW is OFF (P/S high pressure switch is OFF)
