Symptom:

RIGHT MIRROR VERTICAL SENSOR OUT OF RANGE LOW

When Monitored and Set Condition:

RIGHT MIRROR VERTICAL SENSOR OUT OF RANGE LOW

When Monitored:

Continuously when the PCI bus is active.

Set Condition:

This code is set when the mirror sensor feedback to the Memory Seat

Mirror Module is less than the mirror out of range low value stored in EEPROM. Code will
remain for 50 ignition cycles.

POSSIBLE CAUSES

MSMM VERTICAL POSITION LOW

STORED DIAGNOSTIC TROUBLE CODE

RIGHT MIRROR VERTICAL POSITION SIGNAL WIRE SHORT TO GROUND

TEST

ACTION

APPLICABILITY

1

With the DRBIII

t, erase the DTC from Memory Seat Mirror 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 DRB check for the same DTC to reset in the MSMM.
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.
