Ambient Temperature | Resistance |
|---|---|
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?
Yes | GO to AG18 |
|---|---|
No | GO to AG17 |
AG17 CHECK THE DRIVER SEAT BACKREST BLOWER MOTOR THERMISTOR
Disconnect: Driver Seat Backrest Blower Motor C3034. Measure the component side resistance between:
Positive Lead | Measurement / Action | Negative Lead |
|---|---|---|
C3034-5, Component Side | C3034-8, Component Side |
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?
Yes | REPAIR circuit VHS35 (VT/OG) or RHS15 (GY/BN) for an open or high resistance. GO to AG22 |
|---|---|
No | INSTALL a new backrest blower motor. REFER to: Front Seat Backrest Blower Motor (501-10 Front Seats) . GO to AG22 |
AG18 CHECK THE DRIVER SEAT BACKREST BLOWER MOTOR HEATING/COOLING CIRCUITRY CURRENT DRAW
Connect all SCME, blower motor and Body Harness-to-Seat Harness Connectors.
NOTICE: It may be necessary to open the seat wire harness conduit to allow placing the inductive current probe around the circuit as described in the following step. Care must be taken when opening up the wire harness so as not to damage any wiring or connectors. Do not damage any wiring or induce stress on any wiring or connectors. Close up the wire harness once repairs to the seat are complete.
NOTE: Use a commercially available inductive current probe (such as Electronic Specialties Current Probe/Multimeter 685 or a Fluke I410 [used with a digital multimeter]) or the low current probe from the VMM available for use with IDS. If these are unavailable, the inductive current probe feature from a battery tester may be substituted. Place an inductive current probe around circuit CHS01 (GY/VT) near SCME C3265A-J and monitor the current draw. Start the engine and set the driver seat to HIGH heat.
Is the current draw less than 11 amps?
