DTC Detecting Condition and Trouble Area
DTC TroubleshootingDTC Detecting Condition Trouble Area
Mechanical switch failure, fa ilure in switch wiring is
shorted to ground. • ESP
® OFF switch
• ESP ® OFF switch circuit
• ESP ® control module
Step Action YesNo
1 Was “Electronic Stability Pr ogram Check” performed? Go to Step 2.Go to “Electronic
Stability Program
System Check”.
2 Check ESP ® OFF switch condition
Is ESP
® OFF switch is OFF condition? Go to Step 3. ESP
® OFF switch
turned OFF condition
and recheck.
3 Check ESP ® OFF switch
1) Turn ignition switch to OFF position.
2) Remove ESP® OFF switch referring to “ESP ® OFF
Switch Removal and Installation”.
3) Check for proper connection at each terminal of ESP ®
OFF switch.
4) If OK, then check ESP ® OFF switch referring to “ESP ®
OFF Switch Inspection”.
Is it good condition? Go to Step 4. Replace ESP
® OFF
switch.
4 Check ESP ® OFF switch circuit
1) Disconnect ESP ® control module connector.
2) Check for proper connection to ESP ® control module
connector at “E85-7” terminal.
3) If OK, then check resistance between “E85-7” terminal and vehicle body ground.
Is resistance infinity? Substitute a known-
good ESP
® hydraulic
unit / control module
assembly and recheck. “LT GRN/RED” wire
circuit is shorted to
ground.
DTC Detecting Condition
Trouble Area
Input signal voltage from master cylinder pressure sensor
in ESP ® control module is too high or low. • Leakage or air in the hydraulic brake system
• Clearance between brake pad and disc too high
Step
Action YesNo
1 Was “Electronic Stability Pr ogram Check” performed? Go to Step 2.Go to “Electronic
Stability Program
System Check”.
2 Check brake system
1) Check brake system as follows.
• Leakage or air in the hydraulic brake system
• Clearance between brake pad and disc too high
Are they in good condition? Go to Step 3.
Repair, replace or
adjust.
3 Check sensor calibration
1) Calibrate master cylinder pressure sensor referring to
“Sensor Calibration”.
2) Clear all DTC(s) and recheck DTC.
Is DTC C1028 still detected? Substitute a known-
good ESP
® hydraulic
unit / control module
assembly recheck. Master cylinder
pressure sensor
calibration was
incompleted.
