FOR ALL OF VEHICLES
PRECAUTION
1. FOR VEHICLES EQUIPPED WITH SRS AIRBAG AND
SEAT BELT PRETENSIONER
(a) The SEQUOIA is equipped with an SRS (Supplemental
Restraint System), such as the driver airbag, front pas-
senger airbag, side airbag assembly, curtain shield airbag
assembly and seat belt pretensioner.
Failure to carry out service operations in the correct se-
quence could cause the supplemental restraint system to
unexpectedly deploy during servicing, possibly leading to
a serious accident.
Further, if a mistake is made in servicing the supplemental
restraint system, it is possible the SRS may fail to operate
when required. Before servicing (including removal or
installation of parts, inspection or replacement), be sure
to read the following items carefully, then follow the cor-
rect procedure described in this manual.
(b) GENERAL NOTICE
(1) Malfunction symptoms of the supplemental re-
straint system are difficult to confirm, so the diag-
nostic trouble codes become the most important
source of information when troubleshooting. When
troubleshooting the supplemental restraint system,
always inspect the diagnostic trouble codes before
disconnecting the battery (See page DI±1118).
(2) Work must be started after 90 seconds from the
time the ignition switch is turned to the ºLOCKº posi-
tion and the negative (±) terminal cable is discon-
nected from the battery.
(The supplemental restraint system is equipped
with a back±up power source because if work is
started within 90 seconds of disconnecting the neg-
ative (±) terminal cable from the battery, the SRS
may deploy.)
When the negative (±) terminal cable is discon-
nected from the battery, memory of the clock and
audio systems will be cancelled. So before starting
work, make a record of the contents memorized in
each memory system. When work is finished, reset
the clock and audio systems as before. To avoid
erasing the memory of each memory system, never
use a back±up power supply from another battery.

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. 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 SF±80).
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 DI±43).
(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.

16. SET NO.1 CYLINDER TO TDC/COMPRESSION
(a) Turn the crankshaft pulley and align its groove with timing
mark º0º of the No.1 timing belt cover.
(b) Check that the timing marks of the camshaft timing pul-
leys and timing belt rear plates are aligned.
If not, turn the crankshaft 1 revolution (360°).
(c) Turn the crankshaft pulley approx. 50° clockwise, and
align the timing mark of the crankshaft pulley with the cen-
ters of the crankshaft pulley bolt and the No.2 timing belt
idler pulley bolt.
NOTICE:
If the timing belt is disengaged, having the crankshaft
pulley at the wrong angle can cause the piston head and
valve head to come into contact with each other when you
remove the camshaft timing pulley (step 15), causing dam-
age. So always set the crankshaft pulley at the correct
angle.
(d) Remove the crankshaft pulley bolt.
NOTICE:
Do not turn the crankshaft pulley.
17. REMOVE TIMING BELT TENSIONER
HINT:

When re±using the timing belt:
If the installation marks have disappeared, before remove
the timing belt, place 2 new installation marks on the tim-
ing belt to match the timing marks of the camshaft timing
pulleys.

When replacing the timing belt tensioner only:
To avoid meshing of the timing pulley and timing belt, se-
cure one of them with string. And place matchmarks on
the timing belt and RH camshaft timing pulley.
Alternately loosen the 2 bolts, and remove them, the belt ten-
sioner and dust boot.
18. DISCONNECT TIMING BELT FROM CAMSHAFT TIM-
ING PULLEYS
(a) Hold the camshaft timing pulley with SST, and loosen the
tension spring between the LH and RH camshaft timing
pulleys by slightly turning the LH camshaft timing pulley
clockwise.

HINT:
Set the SST so that the claw comes in contact with the camshaft
timing pulley bolt, and tighten the lock nut of the SST.
(b) Disconnect the timing belt from the camshaft timing pul-
leys.
19. REMOVE CAMSHAFT TIMING PULLEYS
(a) Hold the camshaft timing pulley with SST, loosen the 4
bolts of the timing pulley.
SST 09960±10010 (09962±01000, 09963±01000)
(b) Remove the 2 timing pulleys.
20. REMOVE GENERATOR (See page CH±7)
21. REMOVE DRIVE BELT TENSIONER
Remove the bolt, 2 nuts and belt tensioner.
