P2610Soak timer (built into ECM)ECM internal malfunctionECMEngine
running2 trip
CIRCUIT DESCRIPTION
To ensure the accuracy of the EVAP (Evaporative Emission) monitor values, the soak timer, which is built
into the ECM, measures 5 hours (
15 minutes) from when the ignition switch is turned OFF, before the moni-
tor is run. This allows the fuel to cool down, which stabilizes the Fuel Tank Pressure (FTP). When 5 hours
have elapsed, the ECM turns on.
MONITOR DESCRIPTION
5 hours after the ignition switch is turned OFF, the soak timer activates the ECM to begin the EVAP system
monitor. While the engine is running, the ECM monitors the synchronization of the soak timer and the CPU
clock. If these two are not synchronized, the ECM interprets this as a malfunction, illuminates the MIL and
sets the DTC (2 trip detection logic).

INSPECTION PROCEDURE
HINT:

DTC P2610 is set if an internal ECM problem is detected. Diagnostic procedures are not required. ECM
replacement is required.

Read freeze frame data using a hand-held tester or OBD II scan tool. Freeze frame data record the
engine condition when malfunctions are detected. When troubleshooting, freeze frame data can help
determine if the vehicle was moving or stationary, if the engine was warmed up or not, if the air-fuel
ratio was lean or rich, and other data, from the time the malfunction occurred.
1 REPLACE ECM (see page 10-9)
NEXT
CHECK WHETHER DTC OUTPUT RECURS
(a) Connect a hand-held tester to the DLC3.
(b) Turn the ignition switch to ON.
(c) Clear DTCs (see page 05-38).
(d) Start the engine and wait for 10 minutes or more.
(e) On the tester, select the following menu items: DIAGNOSIS / ENHANCED OBD II / DTC INFO / PEND-
ING CODES.
(f) If no pending DTC is displayed, the repair has been successfully completed.

5 INSPECT POWER WINDOW REGULATOR MOTOR ASSY LH (DRIVER SIDE)
(a) Inspect the power window regulator motor assy LH (Driver side) operation.
NOTICE:

Do not apply the battery voltage, because the pulse sensor and limit switch could be damaged
if the battery voltage is applied to terminals 2, 3 and 6 of the power window regulator motor con-
nector.

Be sure to reset the power window regulator motor (initial position setting of limit switch) when
the driver's side power window regulator motor is installed to the regulator.
(1) Check that the motor operates smoothly when the
battery positive voltage is applied to each terminal
of the connector.
Standard:

(b) Inspect the PTC operation inside the power window regulator motor.
NOTICE:

vehicle.
(1) Set a DC 400 A probe of the electrical tester in the wire harness of terminal 4 or 5.
NOTICE:
Match the arrow mark of the probe with the current direction.
(2) Set the door glass in the fully closed position.
(3) When 60 seconds have elapsed after the door glass is fully closed, check now long the current
takes to charge, from approximately 16 - 34 A into 1 A or less, when the power window switch
is turned UP once again.
Standard: Approximately 4 - 90 seconds
(4) When approximately 60 seconds have elapsed after the inspection of the current cut-off, check

HANDLING PRECAUTIONS ON RELATED COMPONENTS
1. BRAKE SYSTEM
The brake system is one of the most important safety components. Always follow the directions and
notes given in brake (32) section of the repair manual for the relevant model when handling brake system
parts.
NOTICE: When repairing the brake master cylinder or TRAC system, bleed the air out of the TRAC sys-
tem.
2. DRIVE TRAIN AND CHASSIS
The drive train and chassis are components that can have great effects on the running performance and
vibration resistance of the vehicle. After installing components in the sections listed in the table below,
perform alignments to ensure correct mounting angles and dimensions. Particularly accurate repair of
the body must also be done to ensure correct alignment.
HINT: Correct procedures and special tools are required for alignment. Always follow the directions giv-
en in the repair manual for the relevant model during alignment and section DI of this section.

Rear WheelsRear Suspension (27) section
Propeller ShaftPropeller Shaft (30) section
3. COMPONENTS ADJACENT TO THE BODY PANELS
Various types of component parts are mounted directly on or adjacently to the body panels. Strictly ob-
serve the following precautions to prevent damaging these components and the body panels during han-
dling.

Before repairing the body panels, remove their components or apply protective covers over the com-
ponents.

Before prying components off using a screwdriver or a scraper, etc., attach protective tape to the tool
tip or blade to prevent damaging the components and the body paint.

Before removing components from the outer surface of the body, attach protective tape to the body to
ensure no damage to painted areas.
HINT: Apply touch-up paint to any damaged paint surfaces.

Before drilling or cutting sections, make sure that there are no wires, etc. on the reverse side.
4. ECU (ELECTRONIC CONTROL UNIT)
Many ECUs are mounted in this vehicle.
Take the following precautions during body repair to prevent damage to the ECUs.

Before starting electric welding operations, disconnect the negative (-) terminal cable from the bat-
tery.
When the negative (-) terminal cable is disconnected from the battery, memory of the clock and audio
systems will be cancelled. So before starting work, make a record of the contents memorized by each
memory system. Then when work is finished, reset the clock and audio systems as before.
When the vehicle has tilt and telescopic steering, power seat and outside rear view mirror, which are
all equipped with memory function, it is not possible to make a record of the memory contents.
So when the operation is finished, it will be necessary to explain this fact to the customer, and request
the customer to adjust the features and reset the memory.

Do not expose the ECUs to ambient temperatures above 80C (176F).
NOTICE: If it is possible the ambient temperature may reach 80C (176F) or more, remove the ECUs
from the vehicle before starting work.

Be careful not to drop the ECUs and not to apply physical shocks to them.

(i) WIRE HARNESS AND CONNECTOR
(1) The SRS wire harness is integrated with the instrument panel wire harness assembly. All the con-
nectors in the system are a standard yellow color. If the SRS wire harness becomes discon-
nected or the connector becomes broken, repair or replace it.
2. ELECTRONIC CONTROL
(a) REMOVAL AND INSTALLATION OF BATTERY TERMI-
NAL
(1) Before performing electronic work, disconnect the
battery negative (-) terminal cable beforehand to
prevent component and wire damage caused by
accidental short circuits.
(2) When disconnecting and installing the terminal
cable, turn the ignition switch and lighting switch
OFF and loosen the terminal nut completely. Per-
form these operations without twisting or prying the
terminal. Remove the battery cable from battery
post.
(3) Clock settings, radio settings, DTCs and other data
are erased when the battery cable is removed. Be-
fore removing the battery cable, record any neces-
sary data.
(4) When disconnecting the battery's negative (-) ter-
minal cable, re-initialize the following systems after
the completion of the operation.
(b) HANDLING OF ELECTRONIC PARTS
(1) Do not open the cover or case of the ECU unless
absolutely necessary. If the IC terminals are
touched, the IC may be rendered inoperative by
static electricity.
(2) To disconnect electronic connectors, pull the con-
nector itself, not the wires.
(3) Be careful not to drop electronic components, such
as sensors or relays. If they are dropped on a hard
floor, they should be replaced.
(4) When cleaning the engine with steam, protect the
electronic components, air filter and emission-re-
lated components from water.
(5) Never use an impact wrench to remove or install
temperature switches or temperature sensors.
(6) When checking the continuity at the wire connector,
insert the tester probe carefully to prevent terminals
from bending.
