* 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.

Circuit/System Testing

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.

瀚慖f less than the specified value, test the 12 V reference circuit for a short to ground or an open/high resistance. If the circuit tests normal,

replace the K40 seat memory control module.

3. Test for 0.3 - 2 V between the signal circuit terminal 2 and ground.

瀚慖f less than the specified range, test the signal circuit for a short to ground or an open/high resistance. If the circuit tests normal, replace

the K40 seat memory control module.

瀚慖f greater than the specified range, test the signal circuit for a short to voltage. If the circuit tests normal, replace the K40 seat memory
