DTC Diagnosis Procedure
1.CHECK OUTPUT SPEED SENSOR POWER CIRCUIT
  1. The ignition switch is OFF.
  2. Disconnect output speed sensor connector.
  3. The ignition switch is ON.
  4. Check voltage between output speed sensor harness connector terminal and ground.

Replace output speed sensor. Refer to Removal and Installation.
 
6.DETECT MALFUNCTIONING ITEMS
Check the following items:
  • Harness open circuit or short circuit between ignition switch and IPDM E/R.
  • Harness open circuit or short circuit between IPDM E/R connector terminal 70 and output speed sensor connector terminal 3.
  • 10A fuse (No.73, located in the IPDM E/R).
  • IPDM E/R
Is the check result normal?
INSPECTION END
Repair or replace malfunctioning parts.
