Tracker 2WD L4-1.6L VIN 6 (2000)
TEST DESCRIPTION
The numbers below refer to the step numbers in the diagnostic table.
1. The Powertrain OBD System Check prompts the technician to complete some basic checks and to store the Freeze Frame data on the scan tool if
applicable. This creates an electronic copy of the data taken when the fault occurred. The information is then stored in the scan tool for later
reference.
2. This step checks whether the scan tool is able to turn ON.
3. This step checks if the scan tool can establish communication on the PCM serial data line.
5. This step checks for B+ at the DLC.
6. This step checks the ground circuits at the DLC.
9. This step checks for an open/shorted to ground serial data circuit, a shorted to battery positive serial data circuit, or for a faulty scan tool.
10. The PCM supplies a low current voltage on the serial data circuit. The normal circuit low current will NOT illuminate a test lamp. If the circuit is
shorted to battery positive the higher current will illuminate the test lamp.
11. The scan tool may be damaged by high current flow on the serial data circuit at DLC terminal 7. Check the scan tool for proper operation on a
known good vehicle that uses terminal 7 of the DLC for serial data communication.
13. This step checks for voltage in the ignition positive voltage circuit that supplies the PCM. An open in this circuit will disable the PCM and the
main relay. The PCM will not provide serial data if the circuit is open.
