REMOVAL
1. Rear Wheels
2. Caliper Assembly
·Remove 2 bolts to remove the caliper assembly
from the support bracket. (Refer to Rear Disc
Brakes in Power Assisted Brake System section.)
Temporarily hang the caliper with wire to avoid
stretching the brake hose.

TRANSMISSION CONTROL SYSTEM (4L30±E)
DTC P0719 TCC Brake Switch Circuit High (Stuck On)
D07RW032
Circuit Description
The TCC brake switch is used to indicate brake pedal
status. The normally opened brake switch signal voltage
circuit is opened.
Brake switch supplies a B+ signal on circuit GRN/YEL to
the PCM when the brakes are applied. The PCM uses
this signal to deenergize the TCC solenoid when the
brakes are applied.
This DTC detects a closed brake switch during
accelerations. This is a type ªDº DTC.
Conditions For Setting The DTC

No OSS DTCs P0722 or P0723.

The PCM detects a closed brake switch/circuit (12
volts) for 2 seconds, and the following events occur
seven consecutive times: vehicle speed is less than 8
km/h (5 mph); then vehicle speed is between 8 and 32
km/h (5 and 20 mph) for 4 seconds; then vehicle
speed is greater than 32 km/h (20 mph) for 4 seconds.
Action Taken When The DTC Sets

If throttle opening is greater than 10% and vehicle
speed is greater than 45 km/h (28 mph), then
disregard brake switch contingency for TCC off
mode.

The PCM will not illuminate the CHECK TRANS
Lamp.
Conditions For Clearing The DTC

The DTC can be cleared from the PCM history by
using a scan tool.
The DTC will be cleared from history when the vehicle
has achieved 40 warmup cycles without a failure
reported.

The PCM will cancel the DTC default actions when
the fault no longer exists and the ignition is cycled ªoffº
long enough to power down the PCM.
Diagnostic Aids

Inspect the wiring for poor electrical connections at
the PCM and TCC brake switch. Look for possible
bent, backed out, deformed or damaged terminals.
Check for weak terminal tension as well. Also check
for a chafed wire that could short to bare metal or
other wiring. Inspect for a broken wire inside the
insulation.

When diagnosing for a possible intermittent short or
open condition, move the wiring harness while
observing test equipment for a change.

Check customer driving habits and/or unusual driving
conditions (i.e. stop and go, highway).

Check brake switch for proper mounting and
adjustment.
Test Description
The numbers below refer to the step numbers on the
diagnostic chart:
3. This test checks for voltage at the brake switch.
6. This test checks the brake switch.
9. This test checks circuit GRN/YEL at the PCM.

8DÐ284 WIRING SYSTEM
Anti-lock Brake System (ABS)
General Description
The circuit consists of EHCU (Electronic Hydraulic
Control Unit), wheel speed sensor, GÐsensor,
stoplight switch or brake switch (w/cruise control),
backup light switch, transmission switchÐ1, 2,
indicator light and data link connector.
EHCU controls brake fluid pressure applied to front
and rear wheels to prevent wheels from locking by
using speed sensor and GÐsensor signals.
Based on wheel speed signals from speed sensor,
EHCU activates solenoid valves incorporated into
the control unit to increase, maintain or decrease
brake fluid pressure.
Refer to AntiÐlock Brake System in Brakes section.
