motor. The module supplies each sensor with a 12 V reference circuit and a low side signal circuit. During seat motor operation, the hall effect
position sensor provides a determined number of pulse signals for every revolution of the motor shaft. The scan tool displays these pulse signals as
counts that range from 0 - 65,535. The module counts the feedback pulses from each sensor to determine seat position and end of travel limits for
each of the seat motors. High scan tool count values indicate forward or upward seat positions while low count values indicate rearward or
downward seat positions.
Conditions for Running the DTC
* DTC B1325 must not be present.
* Module battery voltage must be between 9 - 16 V.
Conditions for Setting the DTC
The seat memory control module does not detect position sensor movement or pulse signals while the adjuster motor is active. The following
conditions will set this DTC:
B1825 01, B2355 01, B2365 01, or B2375 01
The seat memory control module detects a short to battery on the sensor signal circuit.
B1825 06, B2355 06, B2365 06, or B2375 06
The seat memory control module detects a short to ground or an open on the sensor signal circuit.
Action Taken When the DTC Sets
The seat memory control module disables the memory recall and easy exit/entry action commands of the motor monitored by the sensor. The motor
will respond to manual positioning commands.
Conditions for Clearing the DTC
* The current DTC clears when the fault is no longer present and the power mode changes to OFF then back to ACC or RUN.
* The history DTC will clear after 40 consecutive fault-free ignition cycles have occurred.

1. Ignition OFF, disconnect the harness connector at the appropriate driver seat motor listed below for which the DTC set:
* M50 seat front vertical motor
* M55 seat rear vertical motor
* M51 seat horizontal motor
* M56 seat back recline motor
2. Ignition ON, test for B+ between the 12 V reference circuit terminal 4 and ground.

Diagnostic Fault Information
Circuit/System Description
The wheel speeds are detected by active wheel speed sensors and encoder rings. The encoder ring consists of permanent magnets. Each wheel
speed sensor receives 12 V reference voltages from the electronic brake control module (EBCM). The wheel speed sensor produces changing
current between 7-14 mA on the EBCM signal circuit. As the wheel spins, the EBCM uses the frequency of the square wave signal to calculate the
actual wheel speed.
Conditions for Running the DTC
C0035 06 - C0050 06
Ignition ON
C0035 0F - C0050 0F
* Ignition ON
* Vehicle speed is greater than 35 km/h (22 mph)
C0035 18 - C0050 18
* Ignition ON
* Vehicle speed is greater than 10 km/h (6 mph)
C0035 5A - C0050 5A
* Ignition ON
* Vehicle speed is greater than 20 km/h (13 mph)
Conditions for Setting the DTC
