Chrysler RG Voyager. Manual — part 220
Symptom:
DRIVER REAR RISER SENSOR OUT OF RANGE LOW
When Monitored and Set Condition:
DRIVER REAR RISER 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
MEMORY SEAT/MIRROR/ADJUSTABLE PEDALS MODULE 5 VOLT SUPPLY
SEAT 5 VOLT SUPPLY WIRE SHORT TO GROUND
SEAT SENSOR 5 VOLT SUPPLY WIRE OPEN
REAR RISER POSITION SIGNAL CIRCUIT OPEN
REAR RISER POSITION SIGNAL CIRCUIT SHORT TO GROUND
REAR RISER SENSOR LOW
MEMORY SEAT/MIRROR/ADJUSTABLE PEDALS MODULE REAR RISER LOW

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 Rear Riser Sensor connector.
Turn ignition on.
Measure the voltage of the Seat Sensor 5 Volt Supply circuit at rear riser connector.
Is the voltage above 4.5 volts?
All
Yes
→ Go To 3
No
→ Go To 7

Turn ignition off.
Disconnect the Driver Power Seat Rear Riser Position Sensor Connector.
Disconnect the Memory Seat/Mirror/Adjustable Pedals Module C2 Connector.
Measure the resistance of the Rear Riser Position Signal circuit between the rear
riser sensor and the Memory Seat/Mirror/Adjustable Pedals Module connector.
Is the resistance below 5.0 ohms?
All
Yes
→ Go To 4
No
→ Repair the Rear Riser Position Signal circuit for an open.
Perform MEMORY SYSTEM VERIFICATION TEST - VER 1.

Turn ignition off.
Disconnect the Memory Seat/Mirror/Adjustable Pedals Module C2 connector.
Disconnect the Driver Power Seat Rear Riser Position Sensor connector.
Measure the resistance of the Rear Riser Position Signal circuit to ground.
Is the resistance below 1000 ohms?
All
Yes
→ Repair the Rear Riser Position Signal circuit a short to ground.
Perform MEMORY SYSTEM VERIFICATION TEST - VER 1.
No
→ Go To 5
5
Turn ignition off.
Ensure the Memory Seat/Mirror/Adjustable Pedals Module is fully connected before
proceeding.
Disconnect the Driver Power Seat Rear Riser Position Sensor Connector.
Connect a jumper wire between Seat Sensor 5 volt Supply and Rear Riser Position
Signal circuits.
Turn ignition on.
With the DRBIII
t in sensors read the Rear Riser Position Sensor voltage.
Is the voltage above 4.5 volts?
All
Yes
→ Replace the Seat Track Assembly.
Perform MEMORY SYSTEM VERIFICATION TEST - VER 1.
No
→ Go To 6

Symptom:
DRIVER REAR RISER UP SWITCH STUCK
When Monitored and Set Condition:
DRIVER REAR RISER UP SWITCH STUCK
When Monitored:
Continuously when the PCI bus is active.
Set Condition:
If the seat switch is active for 30 seconds, this code will set and the
MSMAPM will ignore the input until the state has changed. Three seconds after the stuck
condition is removed, the seat will resume to normal operation. Code will remain for 50
ignition cycles.
