Suzuki GRAND VITARA JB416, Service Manual

Page: 287 / 474

Electronic Stability Program: 4F-24
4 1) Turn ignition switch to OFF position.
2) Check for proper connection to ESP
®
control module
connector at terminals “E53-1” and “E53-32”.
3) If OK then turn ignition switch to ON position and
measure voltage between each terminal of “E53-1”,
“E53-32” and vehicle body ground.
Are they 10 – 14 V?
Go to Step 5. “WHT/RED” and/or
“WHT/BLU” wire circuit
open.
5 1) Turn ignition switch to OFF position.
2) Check for proper connection to ESP
®
control module
connector at terminals “E53-16” and “E53-47”.
3) If OK, measure resistance between each terminal of
“E53-16”, “E53-47” and vehicle body ground.
Are resistance less than 2
Ω
?
Go to Step 6. Ground circuit for ESP
®
control module open or
high resistance.
6 1) Check if communication is possible by trying
communication with other controller (ECM, TCM, BCM,
4WD control module or SDM).
Is it possible to communicate with other controller?
Go to Step 7. Repair open in common
section of serial data
circuit (“PPL/WHT” wire
circuit) used by all
controllers or short to
ground or power circuit
which has occurred
somewhere in serial
data circuit (“PPL/WHT”
wire circuit).
7 1) Turn ignition switch to ON position.
2) Measure voltage between terminal B of data link
connector and vehicle body ground.
Is voltage 10 – 12 V?
Go to step 8. Terminal B circuit open
or shorted to ground.
8 1) Turn ignition switch to OFF position.
2) Measure resistance between the following terminals;
• Terminal G of data link connector and vehicle body
ground.
• Terminal G1 of data link connector and vehicle body
ground.
Is each resistance 1
Ω
or less?
Go to step 9. Terminal G and/or G1
circuit open or high
resistance.
9 1) Turn ignition switch to OFF position.
2) Check proper connection at “E53-33” (“PPL/WHT” wire)
terminal for serial data circuit.
3) If OK, then check resistance between “E53-33” (“PPL/
WHT” wire) terminal and “PPL/WHT” wire terminal (2) for
serial data circuit in DLC (1).
Is resistance 1
Ω
or less?
Substitute a known-
good ESP
®
hydraulic
unit / control module
and recheck.
Repair high resistance
or open in “PPL/WHT”
wire circuit for anti lock
brake system.
Step Action Yes No
