* Ohms cannot be measured if voltage is present.
Ohms can be measured only in a non-powered
circuit.
•
Voltage between any terminal and ground must
not exceed 500v DC or 500v peak AC.
•
Use caution when measuring voltage above 25v
DC or 25v AC.
•
Use the low current shunt to measure circuits up
to 10A. Use the high current clamp to measure
circuits exceeding 10A.
•
When testing for the presence of voltage or cur-
rent, make sure the meter is functioning cor-
rectly. Take a reading of a known voltage or
current before accepting a zero reading.
•
When measuring current, connect the meter in
series with the load.
•
Disconnect the live test lead before disconnecting
the common test lead.
•
When using the meter function, keep the
DRBIII
t away from spark plug or coil wires to
avoid measuring error from outside interference.

WARNINGS
4.3.1
VEHICLE DAMAGE WARNINGS
Before disconnecting any control module, make
sure the ignition is “off”. Failure to do so could
damage the module.
When testing voltage or continuity at any control
module, use the terminal side (not the wire end) of
the connector. Do not probe a wire through the
insulation; this will damage it and eventually cause
it to fail because of corrosion. Be careful when
performing electrical tests so as to prevent acciden-
tal shorting of terminals. Such mistakes can dam-
age fuses or components. Also, a second code could
be set, making diagnosis of the original problem
more difficult.
4.3.2
ROAD TESTING A COMPLAINT
VEHICLE
Some complaints will require a test drive as part
of the repair verification procedure. The purpose of
the test drive is to try to duplicate the diagnostic
code or symptom condition.
WARNING: REASSEMBLE ALL COMPONENTS
BEFORE ROAD TESTING A VEHICLE. DO NOT
TRY TO READ THE DRBIII
T
SCREEN OR
OTHER TEST EQUIPMENT DURING A TEST
DRIVE. DO NOT HANG THE DRBIII
T
OR OTHER
TEST EQUIPMENT FROM THE REARVIEW
MIRROR DURING A TEST DRIVE. HAVE AN
ASSISTANT AVAILABLE TO OPERATE THE
DRBIII
T
OR
OTHER
TEST
EQUIPMENT.
FAILURE TO FOLLOW THESE INSTRUCTIONS
CAN RESULT IN PERSONAL INJURY OR
DEATH.

DIAGNOSTIC INFORMATION AND
PROCEDURES
43
Symptom:
PEDAL SENSOR OPEN/SHORTED TO GROUND
When Monitored and Set Condition:
PEDAL SENSOR OPEN/SHORTED TO GROUND
When Monitored:
Continuously.
Set Condition:
When the Memory Seat Mirror Adjustable Pedals Module(MSMAPM)
detects a ground condition on the Adjustable Pedal Sensor Signal circuit. When this fault
is set, the pedals will be allowed to move 1.5 seconds and then shut off.
POSSIBLE CAUSES
INTERMITTENT DTC
ADJUSTABLE PEDALS SENSOR FEED CIRCUIT OPEN
ADJUSTABLE PEDALS SENSOR SIGNAL CIRCUIT OPEN
ADJUSTABLE PEDALS SENSOR SIGNAL CIRCUIT SHORTED TO GROUND
ADJUSTABLE PEDALS SENSOR SIGNAL/RETURN CIRCUITS HAVE EXCESSIVE RESISTANCE
ADJUSTABLE PEDALS SENSOR FAULT
MSMAPM - INTERNAL FAULT
TEST
ACTION
APPLICABILITY
1
With the DRBIII
t, erase DTC’s.
With the DRBIII
t, read DTC’s.
Does the DRBIII
t display PEDAL SENSOR OPEN/SHORTED TO GROUND DTC
active?
All
Yes
→ Go To 2
No
→ Go To 9
2
Turn the ignition off.
Ensure the Adjustable Pedals Sensor is fully seated and locked.
Turn the ignition on.
With the DRBIII
t, read the active DTC’s.
Does the DRBIII
t display PEDAL SENSOR OPEN/SHORTED TO GROUND DTC
active?
All
Yes
→ Go To 3
No
→ Go To 9
3
Turn the ignition off.
Disconnect the Adjustable Pedals Sensor harness connector.
Turn the ignition on.
Measure the voltage between the Adjustable Pedals Sensor Feed circuit and the
Adjustable Pedals Sensor Return circuit.
Is the voltage between 4 and 5.2 volts?
All
Yes
→ Go To 4
No
→ Go To 8
