ON-VEHICLE INSPECTION (USING ACC CHECKER 49 9200 010)
76G15X-072
Note:
When checking the actuator on '88 models with EC-AT using this checker, the checker
should be modified as shown below in order to avoid damage of the EC-AT control unit.
Modification Procedure
1. Cut the wire at terminal no.6 indicated on ACC
checker connector.
2. Tape exposed end of wire cut in step 1 as shown.
This modification does not affect the usage of the ACC
checker except when used on the '81 RX-7 and 626
models. When the modified ACC checker is used on
these models, use a jumper wire and jump across
terminal no.6 to 3 indicated on ACC checker connec-
tor as shown.
Function of the ACC CHECKER
A. Check lights
Each item is verified by a check light, as described below.

B.Check Switch
The check switch in the ACC checker is used to
check the actuator operation while the engine is
running. When the check switch is held on after
the engine is started, the engine speed increases
to approximately 2,000 to 3,000 rpm and is main-
tained at that level. When the check switch is
released, the engine speed decreases to idle
speed.
76G15X-073
C.Slide switch
Before using the check switch, first move the slide
switch to the "L" position.
Then use the check switch to increase the engine
rpm.
If the engine rpm stabilizes after increasing to
2,000—3,000 rpm, there is no problem. If there is
no increase at all, or only a slight increase, try again
after setting the slide switch to the "H" position.
If there is still no increase to 2,000—3,000 rpm,
adjust the free play of the actuator inner cable.

Preparation
1. ACC checker installation
Depress the lock hook of the harness connector.
Remove the connector from the ACC control unit
after the ignition switch and main switch are turned
off, and then connect the harness connector to the
ACC checker.
2. Checking the free play of the actuator inner
cable
Remove the clip and adjust the nut so that the ac-
tuator control cable play is as follows when the ca-
ble is pressed lightly.
Standard play: 1—3 mm (0.039—0.118 in)
