| WIRING DIAGRAM
 PROCEDURE
| 1. |
CHECK HARNESS AND CONNECTOR (4 WHEEL DRIVE CONTROL ECU - TRANSFER SHIFT ACTUATOR ASSEMBLY) |
(a) Disconnect the A26 4 wheel drive control ECU connector. (b) Disconnect the D67 transfer shift actuator assembly connector.
(c) Measure the resistance according to the value(s) in the table below.
Standard Resistance: |
Tester Connection | Condition |
Specified Condition | |
A26-6 (SCC) - D67-3 (SCC) |
Always | Below 1 Ω | |
A26-6 (SCC) or D67-3 (SCC) - Body ground |
Always | 10 kΩ or higher |
| NG |
 | REPAIR OR REPLACE HARNESS OR CONNECTOR |
|
OK |
 | |
| 2. |
INSPECT TRANSFER SHIFT ACTUATOR ASSEMBLY (SCC TERMINAL) |
 (a) Disconnect the D67 transfer shift actuator assembly connector.
(b) Measure the resistance according to the value(s) in the table below.
Standard Resistance: DTC P17A5 is output |
Tester Connection | Condition |
Specified Condition | |
3 (SCC) - Body ground |
Always | Below 5 Ω | DTC P17A6 is output |
Tester Connection | Condition |
Specified Condition | |
3 (SCC) - Body ground |
Always | 1 Ω or higher | Text in Illustration |
*a | Component without harness connected
(Transfer Shift Actuator Assembly) |
| OK |
| REPLACE 4 WHEEL DRIVE CONTROL ECU |
|
NG | |
| |
| 3. |
INSPECT SOLENOID COIL SUB-ASSEMBLY |
 (a) Disconnect the A solenoid coil sub-assembly connector.
(b) Measure the resistance according to the value(s) in the table below.
Standard Resistance: DTC P17A5 is output |
Tester Connection | Condition |
Specified Condition | |
2 - Body ground | Always |
Below 5 Ω | DTC P17A6 is output |
Tester Connection | Condition |
Specified Condition | |
2 - Body ground | Always |
1 Ω or higher | Text in Illustration |
*a | Component without harness connected
(Solenoid Coil Sub-assembly) |
| OK |
| REPLACE TRANSFER SHIFT ACTUATOR ASSEMBLY |
| NG |
| REPLACE SOLENOID COIL SUB-ASSEMBLY | |
