DESCRIPTION This DTC is
detected when the 4 wheel drive control ECU, which monitors the B
terminal voltage, determines that the standard voltage is not met and
detects a B terminal system malfunction.

CAUTION / NOTICE / HINT
NOTICE:
- Inspect the fuses for circuits related to this system before performing the following inspection procedure.
- If only past DTCs are output, battery depletion may have occurred in the past.
PROCEDURE
(a) Inspect the battery (3UR-FE: See page , 3UR-FBE: See page
, 1UR-FE: See page
).

2. |
CHECK BATTERY TERMINAL | (a) Check the battery terminals (3UR-FE: See page
, 3UR-FBE: See page
, 1UR-FE: See page
).
NG | |
REPAIR BATTERY TERMINAL OR REPLACE BATTERY |
OK |
| |
3. |
CHECK HARNESS AND CONNECTOR (B TERMINAL) |
(a) Disconnect the 4 wheel drive control ECU connector. |
|
(b) Measure the voltage according to the value(s) in the table below. Standard Voltage:
Tester Connection | Condition |
Specified Condition |
A25-6 (B) - Body ground |
Always | 11 to 14 V | Text in Illustration

| REPAIR OR REPLACE HARNESS OR CONNECTOR |
OK |
| |
4. |
CHECK HARNESS AND CONNECTOR (GND TERMINAL) |
(a) Disconnect the 4 wheel drive control ECU connector.
(b) Measure the resistance according to the value(s) in the table below.
Standard Resistance:
Tester Connection | Condition |
Specified Condition |
A25-5 (GND) - Body ground |
Always | Below 1 Ω | Text in Illustration
