CHECK THE (P67) DRIVER MIRROR VERTICAL POSITION SIGNAL CIRCUIT FOR A SHORT TO THE (P69)
DRIVER MIRROR SENSOR GROUND CIRCUIT OR THE (P64) PASSENGER MIRROR VERTICAL POSITION
SIGNAL CIRCUIT FOR A SHORT TO THE (P66) PASSENGER MIRROR SENSOR GROUND CIRCUIT
For the Driver Memory Mirror System, proceed as follows:
•
Measure the resistance between the (P67) Driver Mirror Vertical
Position Signal circuit and the (P69) Driver Mirror Sensor Ground
circuit in the Driver Memory Mirror Module C1 connector.
For the Passenger Memory Mirror System, proceed as follows:
•
Measure the resistance between the (P64) Passenger Mirror Ver-
tical Position Signal circuit and the (P66) Passenger Mirror Sen-
sor Ground circuit in the Passenger Memory Mirror Module
connector.
Is the resistance below 10000.0 ohms?
Yes, Driver MMM
Repair the (P67) Driver Mirror Vertical Position Signal cir-
cuit for a short to the (P69) Driver Mirror Sensor Ground
circuit.
Perform BODY VERIFICATION TEST – VER 1. (Refer to 8
- ELECTRICAL/ELECTRONIC CONTROL MODULES -
STANDARD PROCEDURE).
Yes, Passenger MMM
Repair the (P64) Passenger Mirror Vertical Position Signal
circuit for a short to the (P66) Passenger Mirror Sensor
Ground circuit.

When Monitored:
Continuously
•
Set Condition:
The (P67) Driver Mirror Vertical Position Signal circuit supplies input to the Driver Memory Mirror Module. DTC
B1D0D will set if the input value is greater than the known good (stored) value for more than 60 ms.
The (P64) Passenger Mirror Vertical Position Signal circuit supplies input to the Passenger Memory Mirror
Module. DTC B1D16 will set if the input value is greater than the known good (stored) value for more than 60
ms.
Possible Causes
FOR THE DRIVER MEMORY MIRROR SYSTEM:
(P67) DRIVER MIRROR VERTICAL POSITION SIGNAL CIRCUIT SHORTED TO VOLTAGE
(P67) DRIVER MIRROR VERTICAL POSITION SIGNAL CIRCUIT OPEN
(P69) DRIVER MIRROR SENSOR GROUND CIRCUIT OPEN
DRIVER OUTSIDE REARVIEW MIRROR SHORTED
DRIVER MEMORY MIRROR MODULE
FOR THE PASSENGER MEMORY MIRROR SYSTEM:
(P64) PASSENGER MIRROR VERTICAL POSITION SIGNAL CIRCUIT SHORTED TO VOLTAGE
(P64) PASSENGER MIRROR VERTICAL POSITION SIGNAL CIRCUIT OPEN
(P66) PASSENGER MIRROR SENSOR GROUND CIRCUIT OPEN
PASSENGER OUTSIDE REARVIEW MIRROR SHORTED
PASSENGER MEMORY MIRROR MODULE
NOTE: This procedure addresses the Driver Memory Mirror system’s circuits and components and the Pas-
senger Memory Mirror system’s circuits and components. Select only that which applies to the system you
are diagnosing.
Diagnostic Test
1.
TEST FOR INTERMITTENT CONDITION
Turn the ignition on.
With the scan tool, record and erase DTCs.
Operate the Mirror Switch in all directions several times.
Cycle the ignition from on to off 3 times.
Turn the ignition on.
With the scan tool, read DTCs.
Does the scan tool display: B1D0D or B1D16 MIRROR VERTICAL POSITION SENSOR INPUT CIRCUIT
HIGH?
Yes
>> Go To 2
No
>> The conditions that caused this code to set are not present at this time. Using the wiring diagram/sche-
matic as a guide, inspect the wiring and connectors.
Perform BODY VERIFICATION TEST – VER 1. (Refer to 8 - ELECTRICAL/ELECTRONIC CONTROL
MODULES - STANDARD PROCEDURE).
