DIAGNOSIS AND TESTING (Continued)

Pinpoint Tests

PINPOINT TEST A : THE POWER SEAT IS INOPERATIVE

Test Step

Result / Action to Take

A1

CHECK FOR POWER AT SEAT

Measure the voltage between the power pins on connectors CON-1

Yes

pins 1 and 2, CON-1 pin 1 and CON-2 pin 6.

Go to A2

Is the voltage greater than 10 volts?

No

Replace the fuse if CON-1 problem. Check BEM
if CON-2 problem.

A2

CHECK CONNECTION AND CIRCUIT CONTINUITY

Measure voltage between the power and grounds on the module

Yes

connector, CON-4 pins 1 and 8 also 1 and 7.

Replace the harness. Refer to removal and
installation instructions in this chapter.

Is the voltage within 0.5 of a volt of that measured in A1?

No

Replace seat module. Refer to removal and
installation instructions in this chapter.
