P2716 |
MONITOR DESCRIPTION
When an open or short in the shift solenoid valve SLT circuit is detected, the ECM interprets this as a fault. The ECM will illuminate the MIL and store the DTC.

Low Power Supply Voltage Malfunction (C1241)
DESCRIPTION
If a malfunction is detected in the power supply circuit, the skid control ECU
(brake actuator assembly) stores this DTC and the fail-safe function prohibits ABS
operation.
This DTC is stored when the +BS terminal voltage deviates from the DTC detection
condition due to a malfunc ...

PROCEDURE
1. INSPECT OIL CLEARANCE
(a) Using a micrometer and caliper gauge, measure the oil seal clearance.
Standard clearance:
0.021 to 0.043 mm (0.0008 to 0.0017 in.)
Maximum clearance:
0.07 mm (0.0028 in.)
If it is greater than the maximum, replace the vane pump assembly.
