Inspection Procedure

When the pattern select (2ND) switch is pushed, switch contact is made and 2nd mode is selected. To cancel 2nd mode, push the pattern select (2ND) switch 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 PATTERN SELECT (2ND) SWITCH 
   1. Remove the suspension control switch (See REMOVAL ).
   2. Measure the resistance according to the value(s) in the table below.

      Standard Resistance 

      RESISTANCE SPECIFICATION
      
      

      Tester Connection	Switch Condition	Specified Condition
      17 (2ND) - 20 (E)	Pattern select (2ND) switch continuously pressed	Below 1 Ω
      17 (2ND) - 20 (E)	Pattern select (2ND) switch released	10 kΩ or higher

   NG: REPLACE PATTERN SELECT (2ND) SWITCH (SUSPENSION CONTROL SWITCH)  (See REMOVAL )

3. CHECK HARNESS AND CONNECTOR (PATTERN SELECT (2ND) SWITCH - BODY GROUND) 
   1. Disconnect the V4 suspension control switch connector.
   2. Measure the resistance according to the value(s) in the table below.

      Standard Resistance 

      RESISTANCE SPECIFICATION
      
      

      Tester Connection	Condition	Specified Condition
      V4-20 (E) - Body ground	Always	Below 1 Ω

   NG: REPAIR OR REPLACE HARNESS OR CONNECTOR

4. CHECK HARNESS AND CONNECTOR (PATTERN SELECT (2ND) SWITCH - ECM) 
   1. Disconnect the A38 ECM connector.
   2. Measure the resistance according to the value(s) in the table below.

      Standard Resistance 

      RESISTANCE SPECIFICATION
      
      

      Tester Connection	Switch Condition	Specified Condition
      A38-4 (SNWI) - Body ground	Pattern select (2ND) switch continuously pressed	Below 1 Ω
      A38-4 (SNWI) - Body ground	Pattern select (2ND) switch released	10 kΩ or higher

   NG: REPAIR OR REPLACE HARNESS OR CONNECTOR
