key NISSAN PRIMERA 1999 Electronic Repair Manual

IWhen connecting or disconnecting pin connectors into or
from TCM, take care not to damage pin terminals (bend or
break).
Make sure that there are not any bends or breaks on TCM
pin terminal, when connecting pin connectors.
IBefore replacing TCM, perform TCM input/output signal
inspection and make sure whether TCM functions prop-
erly or not. (See page AT-41.)
IAfter performing each TROUBLE DIAGNOSIS, perform
ªDTC (Diagnostic Trouble Code) CONFIRMATION PROCE-
DUREº.
The DTC should not be displayed in the ªDTC CONFIRMA-
TION PROCEDUREº if the repair is completed.
IIt is very important to perform functional tests whenever they
are indicated.
IExtreme care should be taken to avoid damage to O-rings,
seals and gaskets when assembling.
IWhen the CVT drain plug is removed, only some of the fluid is
drained. Old CVT fluid will remain in torque converter and CVT
fluid cooling system.
Always follow the procedures under ªChanging CVT Fluidº in
the MA section when changing CVT fluid.
Service Notice or PrecautionsNCAT0004FAIL-SAFENCAT0004S01The TCM has an electronic Fail-Safe (limp home mode). This allows the vehicle to be driven even if a major
electrical input/output device circuit is damaged.
Under Fail-Safe, the vehicle always runs even with a shift lever position of ªLº or ªDº. The customer may com-
plain of sluggish or poor acceleration.
When the ignition key is turned ªONº following Fail-Safe operation, CVT or SPORT indicator lamp blinks for
about 8 seconds. [For ªTCM SELF-DIAGNOSTIC PROCEDURE (No Tools)º, refer to AT-25.]
Fail-Safe may occur without electrical circuit damage if the vehicle is driven under extreme conditions (such
as excessive wheel spin followed by sudden braking). To recover normal shift pattern, turn the ignition key
ªOFFº for 5 seconds, then ªONº.

because piston will pop out.
lBe careful not to damage piston boot or get oil on rotor.
Always replace shims in replacing pads.
lIf shims are rusted or show peeling of rubber coat,
replace them with new shims.

Inspection
Caliper
CAUTION:
Use brake fluid to clean cylinder. Never use mineral oil.
Cylinder Body
lCheck inside surface of cylinder for score, rust, wear, dam-
age or presence of foreign materials. If any of the above
conditions are observed, replace cylinder body.
lMinor damage from rust or foreign materials may be elimi-
nated by polishing surface with a fine emery paper.
Replace cylinder body if necessary.
Torque Member
Check for wear, cracks or other damage. Replace if necessary.
Piston
CAUTION:
Piston sliding surface is plated. Do not polish with emery
paper even if rust or foreign matter is stuck to sliding sur-
face.
Check piston for score, rust, wear, damage or presence of for-
eign materials.
Replace if any of the above conditions are observed.
