Symptom:
DRIVER RECLINER SENSOR OUT OF RANGE LOW
When Monitored and Set Condition:
DRIVER RECLINER SENSOR OUT OF RANGE LOW
When Monitored:
Continuously when the PCI bus is active.
Set Condition:
This condition is immediately set when the seat motor potentiometer
feeds a value lower than the Memory Seat/Mirror/Adjustable Pedals Module has stored in
EEPROM. Code will remain for 50 ignition cycles.
POSSIBLE CAUSES
SEAT 5 VOLT SUPPLY WIRE SHORT TO GROUND
SEAT SENSOR 5 VOLT SUPPLY WIRE OPEN
RECLINER POSITION SIGNAL CIRCUIT OPEN
RECLINER POSITION SIGNAL CIRCUIT SHORT TO GROUND
MEMORY SEAT/MIRROR/ADJUSTABLE PEDALS MODULE 5 VOLT SUPPLY
RECLINER SENSOR LOW
MEMORY SEAT/MIRROR/ADJUSTABLE PEDALS MODULE RECLINER LOW
STORED DIAGNOSTIC TROUBLE CODE

ACTION
APPLICABILITY
1
With the DRBIII
t, erase the DTC from Memory Seat/Mirror/Adjustable Pedals
Module.
Operate the driver’s power seat and memory system.
Turn the ignition switch to the Off position then start the engine and let run for one
minute.
With the DRBIII
t check for the same DTC to reset in the MSMAPM.
Did the same DTC reset?
All
Yes
→ Go To 2
No
→ Using the wiring diagram/schematic as a guide, inspect the
wiring and connectors for an intermittent condition.
Perform MEMORY SYSTEM VERIFICATION TEST - VER 1.
2
Ensure the Memory Seat/Mirror/Adjustable Pedals Module is fully connected before
proceeding.
Disconnect the Driver Power Seat Recliner Position Sensor connector.
Turn ignition on.
Measure the voltage of the Seat Sensor 5 Volt Supply circuit at Recliner sensor
connector.
Is the voltage above 4.5 volts?
All
Yes
→ Go To 3
No
→ Go To 7
