CAUTION / NOTICE / HINT
NOTICE:
When replacing the skid control ECU (master cylinder solenoid), perform calibration
(See page
).
PROCEDURE
|
1. |
INSPECT SKID CONTROL ECU (EXI4) |
(a) Disconnect the S1 skid control ECU (master cylinder solenoid) connector.
|
(b) Measure the voltage according to the value(s) in the table below. Standard Voltage:
|
|
| NG | |
GO TO STEP 3 |
|
|
2. |
CHECK TEST MODE DTC |
(a) Switch the vehicle to test mode, perform the 4WD detection switch signal
check, and then check that DTC C1282 is cleared (See page
).

PROCEDURE
1. INSPECT CYLINDER BLOCK FOR WARPAGE
(a) Using a precision straightedge and feeler gauge, measure the warpage
of the contact surface of the cylinder head gasket.
Standard warpage:
0 to 0.05 mm (0 to 0.00197 in.)
Maximum warpage:
0.07 mm (0.00276 ...
