1-4 Upshift System Check (Manual Transmission)

  1. Turn ignition off. Depress clutch and place transmission in 1st gear. Shift transmission into 2nd or 3rd gear. If transmission cannot be shifted into 2nd or 3rd gear, check for short to voltage on circuit between 2nd-3rd gear blockout relay and 2nd-3rd gear blockout solenoid, defective 2nd-3rd gear blockout solenoid or internal mechanical transmission problem. See Figure .
  2. Turn ignition on with engine not running. Depress clutch and ground DLC test terminal "B". Attempt to shift transmission into 2nd or 3rd gear. If transmission cannot be shifted into 2nd or 3rd gear, system is functioning correctly.
  3. If transmission can be shifted into 2nd and 3rd gear, turn ignition off. Disconnect 2nd-3rd gear blockout relay connector. Turn ignition on and check for voltage from ground to harness terminals No. 85 (Pink wire) and No. 30 (Pink wire). If voltage is not present on both harness terminals, check for blown fuses or open circuit to terminal which did not illuminate test light.
  4. If test light illuminated when touched to either terminals, connect test light from battery voltage to terminal No. 86 (Gray wire) of 2nd-3d gear blockout relay harness connector.
  5. If test light does not illuminate, check for open in circuit No. 324 (Gray wire) between relay and PCM, poor PCM terminal contact or defective PCM. If test light does illuminate, perform 1-4 UPSHIFT SYSTEM RELAY test procedures below.
