2. If continuity is not as specified, replace the switch.
For RHD
1. Apply 12V to the "B" terminal of the unit and con-
nect "E" terminal to the ground.
2. Confirm that the two paralleled lamps come on
when connected between the "L" terminal and the
ground.
Caution
Do no reverse the polarity of the electrical
source to the terminals.

1 5 CRUISE CONTROL SYSTEM
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.
