Using Jumper Wire
- Turn ignition on. Install Jumper Wire (SST 09843-18040) between terminals TC and E1 on data link connector No. 1. See Fig 2. Data link connector No. 1 is located in engine compartment on passenger's side front fender, just behind the air cleaner.
- Note display operation of Malfunction Indicator Light (MIL) on instrument panel. MIL may also be referred to as the CHECK ENGINE light and is located on instrument panel, just below the speedometer.
- Normal code and Diagnostic Trouble Code (DTC) 12 will be displayed by the MIL. See Fig 3. If a problem exists in the engine immobilizer system, a DTC 99 will be displayed by the MIL. See Fig 3. If DTC 99 is displayed, proceed to TROUBLE SHOOTING SYMPTOMS table under TROUBLE SHOOTING for system diagnosis by trouble symptom.
- Remove jumper wire. Once all repairs are performed, clear DTCs from Engine Control Module (ECM). See CLEARING CODES .
- If MIL fails to operate when jumper wire is installed, check wiring circuit between TC terminal on DLC No. 1 and ECM. For ECM terminal identification, see Figure. The ECM is located behind the glove box.
