Inspection Procedure

When the pattern select switch (2ND) is pushed, switch contact is made and 2nd mode is selected. To cancel 2nd mode, push the pattern select switch (2ND) once again.

HINT:

2nd mode is automatically canceled when the engine switch is turned off.

1. DRIVING TEST 

   HINT:

   The driving test should be performed on a paved road (nonskid road).

   1. Start the engine.
   2. Turn the 2ND switch off (normal drive mode).
   3. Confirm vehicle response by driving from a parked position to fully depressing the accelerator pedal.
   4. Turn the 2ND switch on and perform the same check as above.

   When driving the vehicle with the 2ND switch on and off, check that there is a difference in acceleration.

   OK: There is a difference in acceleration. 

   NG:  Go to step  2

   OK: PROCEED TO NEXT CIRCUIT INSPECTION SHOWN IN PROBLEM SYMPTOMS TABLE  (See PROBLEM SYMPTOMS TABLE )

2. INSPECT NO. 1 PATTERN SELECT SWITCH ASSEMBLY (2ND) 
   1. Remove the No. 1 pattern select switch assembly (See PATTERN SELECT SWITCH ).
   2. Measure the resistance according to the value(s) in the table below.

   Standard Resistance

   OK: Go to next step 

3. CHECK HARNESS AND CONNECTOR (NO. 1 PATTERN SELECT SWITCH ASSEMBLY - BODY GROUND) 
   1. Disconnect the V5 No. 1 pattern select switch assembly connector.
   2. Measure the resistance according to the value(s) in the table below.
