Wiper Signal Circuit

CRUISE CONTROL: DYNAMIC LASER CRUISE CONTROL SYSTEM: Wiper Signal Circuit
- Wiper Signal Circuit

DESCRIPTION

The distance control ECU detects wiper operation. If the windshield wipers operate in the HI or LO mode, the cruise control is canceled and the warning sound "pong" is emitted once. In addition, the following warnings will continue until the cruise control main switch is turned off:

* The CRUISE main indicator light blinks.

* The master warning light illuminates.

* The warning code "E2" is displayed on the display in the combination meter.

After HI or LO wiper operation stops, pushing the cruise control main switch to + (ACCEL)/RES (RESUME) will resume the vehicle speed set prior to cancellation.

Cruise control is available when the windshield wipers operate in the intermittent mode.

INSPECTION PROCEDURE

PROCEDURE

1. INSPECT WIPER SYSTEM

Check that the windshield wipers operate in HI mode.

OK:

Wiper function is normal.

NG -- GO TO WIPER AND WASHER SYSTEM (Front wipers do not operate in LO or HI.) Testing and Inspection
OK -- Continue to next step.

2. CHECK HARNESS AND CONNECTOR (DISTANCE CONTROL ECU - WINDSHIELD WIPER SWITCH)

(a) Disconnect the distance control ECU connector and windshield wiper switch connector.





(b) Measure the resistance according to the value(s) in the table below.

Standard Resistance:





NG -- REPAIR OR REPLACE HARNESS OR CONNECTOR

OK -- PROCEED TO NEXT SUSPECTED AREA SHOWN IN PROBLEM SYMPTOMS TABLE Dynamic Laser Cruise Control System
