Check auto cruise switch

(1)

IG "OFF" and disconnect auto cruise switch connector.

(2)

Measure resistance between terminals 3 and 4 of auto cruise switch connector with each switch depressed.(Component side)

(3)

Measure resistance between terminals 4 and 5 of auto cruise switch connector with each switch depressed.(Component side)

a.

Specification :

Item

Resistance(Ω)

ON/OFF switch

3.9 kΩ ± 5% between terminals 3 and 4 at M14 connector

SET switch

220 Ω ± 5% between terminals 4 and 5 at M14 connector

RESUME switch

910 Ω ± 5% between terminals 4 and 5 at M14 connector

CANCEL switch

0 Ω ± 5% between terminals 4 and 5 at M14 connector

(4)

Is the measured resistance within specification ?

YES

▶ Substitute with a known - good PCM and check for proper operation.

If the problem is corrected, replace PCM and go to "Verification of Vehicle Repair" procedure.

NO

▶ Substitute with a known - good auto cruise switch and check for proper operation.

If the problem is corrected, replace auto cruise switch and go to "Verification of Vehicle Repair" procedure.

caution

There is a memory reset function on scantool that can erase optional parts automatically detected and memorized by PCM. After testing PCM on the vehicle, use this function to reuse the PCM on the others
