APPLIED MODEL
All 1990-1993 300ZX (Z32)

 

AFFECTED VIN RANGE:

JN1RZ24A*LX000001 JN1RZ24H*PX538576 JN1RZ26A*LX000001 JN1RZ26H*PX538160 JN1CZ24A*LX000001 JN1CZ24H*PX536696 JN1RZ27H*PX000001 JN1RZ27H*PX003480

 

INTRODUCTION

An electrical problem in the power transistor unit may cause poor driveability and/or rough idle. A counter measure power transistor unit has been developed to resolve this incident.

DEALER RESPONSIBILITY

It is the dealer's responsibility to check each vehicle within the range of this campaign which for any reason enters the service department. This includes vehicles purchased from private parties or presented by transient (tourist) owners and vehicles in dealer inventory.

SERVICE PROCEDURE

The engine should be "OFF", the parking brake applied and the transmission placed in park (if applicable) before beginning service on the vehicle.

1.Open the Hood.

 

2.Remove the air ducting to the throttle body.

 

3.Disconnect the power transistor harness connectors.

 

4.Remove the four bolts holding the power transistor to the timing belt cover.

 

5.Install the new power transistor bracket.

 

6.Install the new power transistor.

 

7.Connect the power transistor sub harness connectors to the existing engine harness connectors for the old power transistor.

 

8.Secure the harnesses into the clip on the timing belt cover. Tie wrap the other harness to the upper radiator hose as shown in the illustration above. Do Not over tighten the tie wrap on the radiator hose, as this will restrict coolant flow.

 

NOTE: Keep clearance at least 5 mm between the air duct and the clip/sub-harness. Keep clearance of at least 5 mm between connector and hood support rod.

 

9.Install air duct to throttle body.

 

10.Close the hood.
