HOW TO USE THIS MANUAL B
This manual provides information on the electrical circuits installed on vehicles by
dividing them into a circuit for each system.
The actual wiring of each system circuit is shown from the point where the power
source is received from the battery as far as each ground point. (All circuit
diagrams are shown with the switches in the OFF position.)
When troubleshooting any problem, first understand the operation of the circuit
where the problem was detected (see System Circuit section), the power source
supplying power to that circuit (see Power Source section), and the ground points
(see Ground Point section). See the System Outline to understand the circuit
operation.
When the circuit operation is understood, begin troubleshooting of the problem
circuit to isolate the cause. Use Relay Location and Electrical Wiring Routing
sections to find each part, junction block and wiring harness connectors, wiring
harness and wiring harness connectors, splice points, and ground points of each
system circuit. Internal wiring for each junction block is also provided for better
understanding of connection within a junction block.
Wiring related to each system is indicated in each system circuit by arrows
(from__, to__). When overall connections are required, see the Overall Electrical
Wiring Diagram at the end of this manual.

6. MANUAL CANCEL CONTROL
When each of the following signals is input during driving with cruise control, the cruise control is released with turning the
cruise control requirement to 0. (The memorized speed is maintained when following signals except the signal, main switch
OFF is input.)
*Stop light switch ON (Pressing the brake pedal)
*Control switch's cancel switch ON
*Main switch OFF
7. AUTO CANCEL FUNCTION
A) The memorized speed is erased and the control is canceled if the following conditions occur. The power indicator blinks
at that time until the main switch is turned ON. The speed control is unavailable unless the main switch is turned ON
again.
*When the stop light switch breaks or short±circuits.
*When sudden change of the running speed signal occur.
B) The memorized speed is erased and the control is canceled if the following conditions occur.
*When the malfunction of the stop light switch input circuit occurs.
*When the running speed becomes slower than 40km/h.
*When the running speed becomes slower than the speed that 16 km/h subtracted from the memorized speed.
8. REGENERATIVE SYSTEM OPERATION
This system operates the motor as a generator to change the kinetic energy of the vehicle into the electricity when accel
pedal release or foot braking controls the vehicle, and store the electricity in the battery.

5. CHECK FOR INTERMITTENT PROBLEMS
TOYOTA hand±held tester only:
By putting the vehicle's ECM in check mode, 1 trip detection logic is possible instead of 2 trip detection logic
and sensitivity to detect open circuits is increased. This makes it easier to detect intermittent problems.
(1) Clear the DTC (See step 3).
(2) Set the check mode (See step 3).
(3) Perform a simulation test (See page IN±30).
(4) Check the connector and terminal (See page IN±41).
(5) Handle the connector (See page IN±41).
6. BASIC INSPECTION
When the malfunction code is not confirmed in the DTC check, troubleshooting should be performed in the
order for all possible circuits to be considered as the causes of the problems. In many cases, by carrying
out the basic engine check shown in the following flow chart, the location causing the problem can be found
quickly and efficiently. Therefore, use of this check is essential in engine troubleshooting.
1 Is battery positive voltage 11 V or more when engine is stopped?
NO Charge or replace battery.
YES
2 Does engine start?
NO Go to step 6.
YES

1. INSPECT WIRELESS DOOR LOCK TRANSMITTER
OPERATION
HINT:
Refer to ºWireless door lock control receiver and transmitter re-
placementº on page BE±87.
(a) Using a screwdriver, remove and cover.
(b) Remove the battery (lithium battery).
(c) Install a new or normal battery (lithium battery).
HINT:
When a new or normal battery can not be obtained, connect 2
new 1.5 V batteries in series, connect the battery (+) to the bat-
tery receptacle side terminal and battery (±) to the bottom termi-
nal, then apply 3 V voltage to the transmitter.
(d) In the location where is approx. 1 M away from driver's
outside handle in the right direction, and check the trans-
mitter operation when pressing transmission switch on
the surface of the transmitter body.
Standard:
Remote control of vehicle door lock can be operated.
HINT:

The minimum operation distance differs according to op-
erator, the way of holding, and location.

As weak wave is used, operation distance might be short-
ened when noise is detected in strong wave or used fre-
quency.
(e) Install the battery (lithium battery).
(f) Install a cover so that rubber cover is not distorted or
slipped off.
