NOTE: The ohmmeter must be connected with the positive lead to pin 7 and the negative lead to pin 4 when measuring. Ohmmeter leads incorrectly connected results in false readings and leads to incorrect identification of components that are not damaged. Measure the component side resistance between:
Positive Lead | Measurement / Action | Negative Lead |
|---|---|---|
C3039-7, Component Side | C3039-4, Component Side |
Is the resistance between 240K and 400K ohms?
Yes | GO to AA15 |
|---|---|
No | INSTALL a new passenger seat backrest blower motor. REFER to: Front Seat Backrest Blower Motor (501-10 Front Seats) . GO to AA22 |
AA15 CHECK THE PASSENGER SEAT BACKREST BLOWER MOTOR INSTALLATION AND FOR CRUSHED SEAT BACKREST
Ignition OFF. Remove the passenger seat. REFER to: Front Seat (501-10A Front Seats, Removal and Installation). Remove the passenger seat backrest cover. REFER to: Front Seat Backrest Cover (501-10A Front Seats, Removal and Installation). Inspect the passenger seat backrest for the following:
Blower motor correctly installed Backrest foam pad crushed or restricted
Is the passenger seat backrest blower motor correctly installed and are there no signs of damage to the foam pad?
Yes | INSTALL the passenger seat backrest cover and seat. GO to AA18 |
|---|---|
No | CORRECTLY install the passenger seat backrest blower motor or INSTALL a new passenger seat backrest foam pad. GO to AA22 |
AA16 CHECK THE PASSENGER SEAT BACKREST BLOWER MOTOR THERMISTOR AND WIRING
REFER to: Supplemental Restraint System (SRS) Depowering (501-20B Supplemental Restraint System, General Procedures). Disconnect: Passenger Side Airbag In-line C219. Disconnect: SCME C3265B. Measure:
Click to display connectors
Positive Lead | Measurement / Action | Negative Lead |
|---|---|---|
C3265B-4 | C3265B-5 |
Compare the measured resistance value with the following table:
Ambient Temperature | Resistance |
|---|---|
0-10° C (32-50° F) | 2,782-1,663 ohms |
10-20° C (50-68° F) | 1,837-1,140 ohms |
20-30° C (68-86° F) | 1,260-806 ohms |
30-40° C (86-104° F) | 893-570 ohms |
40-50° C (104-122° F) | 630-428 ohms |
Is the resistance within the limits indicated?
