4F-24 Electronic Stability Program:
Step
6 1) Check if communication is possible by trying
communication with others control module.
Is it possible to communicate with others control module?
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?
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
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).

Go to Step 7.
Go to step 8.
Go to step 9.
Substitute a known-
good ESP® hydraulic
unit / control module

Repair open in common
section of serial data
circuit ("PPL/WHT" wire
circuit) used by all
control modules or short
to ground or power
circuit which has
occurred somewhere in
serial data circuit ("PPL/
WHT" wire circuit).
Terminal B circuit open
or shorted to ground.
Terminal G and/or G1
circuit open or high
resistance.
Repair high resistance
or open in "PPL/WHT"
wire circuit for ESP®
system.
