Scheme 28

Scheme 28: Monitor Scantool Data

Connect scantool to Data Link Connector (DLC).
Ignition "ON" & Engine "OFF".
Press the ESC (ESP) SWITCH.
Monitor the "ESC (ESP) Off Switch" parameter on the scantool. Normal data
Whenever the switch is pushed up/down, is the ESC off switch's scantool data changed ON/OFF? YES Fault is intermittent caused by poor connection in ESC switch line or was repaired and HECU memory was not cleared. Thoroughly check connectors for looseness, poor connection, bending, corrosion, contamination, deterioration, or damage. Repair or replace as necessary and then go to «VERIFICATION OF VEHICLE REPAIR»(ref-674570-S00318557952014120300000) procedure. NO Go to «TERMINAL AND CONNECTOR INSPECTION»(ref-674570-S28018032422014120300000) procedure.

Brake Light Switch	Voltage Range of "High"	Voltage Range of "Low"

Scheme 30

Scheme 30: Monitor Scantool Data

Connect scantool to Data Link Connector (DLC).
Ignition "ON" & Engine "OFF".
Press the brake pedal.
Monitor the "BRAKE LAMP SWITCH" parameter on the scantool. Normal data
Whenever brake pedal is pushed down, is the brake switch's scantool data changed ON/OFF? YES Fault is intermittent caused by poor connection in brake light switch line and/or HECU's connector or was repaired and HECU memory was not cleared. Thoroughly check connectors for looseness, poor connection, bending, corrosion, contamination, deterioration, or damage. Repair or replace as necessary and then go to «VERIFICATION OF VEHICLE REPAIR»(ref-674570-S20352509252014120300000) procedure. NO Go to «TERMINAL AND CONNECTOR INSPECTION»(ref-674570-S08335219332014120300000) procedure.
