R33(Vspec and Regular)

Self Diagnosis Procedure R33(GTR and Vspec) and R34(GT-R) not Vspec

1)Drive vehicle at 30 km/hr for at least 1 minute. Bring vehicle to a full stop. Do not turn off engine. Look at LED at top of control unit (red lamp). Note the number of times it blinks ON and OFF.

If two or more systems are malfunctioning, all warning lamps will blink ON and OFF

2) After completing required maintenance procedures, be sure to erase results of self diagnosis testing from memory

3) Once again drive vehicle at 30 km/hr for at least 1 minute. Check that the 4wd warning lamp and ABS warning lamp are off.

How to Erase Self Diagnosis results - R33 - R34

1) Remove cables from battery terminals. Also remove ETS/ABS control unit connectors.


R34 ATTESA E-TS Pro (Vspec)

Self Diagnostic Procedure

1. Drive vehicle at approx. 30 km/h for approx. 1 minute

2. Stop vehicle and start diagnosis

3. Turn ignition switch "OFF"

4. Ground the self diagnostic terminal 4

5. Turn the ignition switch " ON" to start the self diagnostic results mode

CAUTION

KEEP terminal 4 grounded during self diagnosis

Do not depress brake pedal (Self diagnosis would not start)

Do not start engine (Self diagnosis would not start)

6. After 3 or 4 seconds, ABS warning lamp starts blinking to indicate the malfunction code

Transfercase differences

  • The R32/R33 and R34 transfer case are different. Besides the physical bolt pattern differences, there are other differences.

HKS ETC - Field ETS

The HKS ETC is used for drag racing, and in order to do a burnout. The Field ETS is used to alter the torque split on the road course.
