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.
Function of the ACC CHECKER
