TRANSMISSION CONTROL SYSTEM (4L30–E)7A1–67
DTC P1850 Brake Band Apply Solenoid Malfunction
D07RW009
Circuit Description
The brake band apply solenoid is a normally open
solenoid which controls the flow of fluid for brake band
application. The Powertrain Control Module (PCM)
uses Pulse Width Modulation (PWM) and changes
the duty cycle to control the solenoid. The PCM turns
the solenoid on (energized) and off (deenergized) at a
constant frequency. The length of time the solenoid is
energized during each on/off cycle is called the pulse
width. By varying or “modulating” the pulse width, the
solenoid output pressure is changed. Since the
solenoid is normally open, increasing the pulse width
increases the duty cycle and decreases the output
pressure. PWM control provides smooth band
application without an accumulator. The band is only
applied in first and second gears.
In the event of an electrical failure (open), the
solenoid regulates at the maximum oil flow (0% duty
cycle).
The solenoid is activated by current. This current is
produced by applying a voltage to one side (the High
side) and a ground to the other side (Low side).
The High Side Driver (HSD) is a circuit of the PCM
that acts as a switch between the solenoids and the
supply voltage. The High side of the solenoid is
permanently supplied with voltage. When the ignition
is off, the HSD is turned off.This DTC detects a continuous open or short to ground in
the brake band apply solenoid circuit or the brake band
apply solenoid. This is a type “D” DTC.
Conditions For Setting The DTC
Battery voltage is between 10 and 16 volts.
Ignition is “on”, Engine “run”.
The PCM commands the solenoid “on” and the
voltage remains high (B+) or the PCM commands the
solenoid “off” and the voltage remains low (zero
volts).
All conditions met in 1.3 seconds.
Action Taken When The DTC Sets
Inhibit brake band apply solenoid.
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 “off”
long enough to power down the PCM.

2. Adjust clutch padel adjusting bolt by backing it out
half a turn, and measure the clearance (
)
between the clutch pedal arm and the adjusting
bolt.

3. Lock the lock nut.
Clutch Switch and Clutch Pedal Clearance (
)
0.5 mm – 1.5 mm (0.020 in – 0.059 in)
5. After adjusting the clutch pedal height, push the
clutch pedal by hand rightly to check the clutch pedal
free play (4) to within specification.

6. Clutch pedal engagement height inspection:
1. Operate the parking brake lever and block the
wheels.
2. Start the engine, fully step on the clutch pedal,
and move the shift lever to 1st position.
3. With the engine idling, release the clutch pedal
slowly and measure its stroke just prior to its
clutching position.
Clutch Pedal Engagement Height (14)
MIN. 30 mm (1.18 in)
7. If the measured value exceeds the specified limit,
check the following points. Repair if necessary:
Hydraulic circuit for fluid leakage or air in circuit.
Clutch disc warped.
Diaphragm spring weakened or tip of fingers worn.
Driven plate sticking on sprines.
Release bearing worn or damaged.
Master cylinder and slave cylinder worn.
