Specified value: 1.5 ohms Max.
If the specified value was not obtained:
-
Check the wiring connection for an open circuit, short circuit to Battery (+) or Ground (GND).
-
Check the wiring connection for damage, corrosion, loose or broken terminals.
-
If necessary, repair the faulty wiring connection.
If no malfunction is found in the wiring:
-
Replace the Data Bus On Board Diagnostic Interface J533.
Final procedures
After repair work, the following work steps must be performed in the following sequence:
1. Check the DTC memory. See: Testing and Inspection/Scan Tool Testing and Procedures/Diagnostic Mode 03 - Read DTC Memory
2. If necessary, erase the DTC memory. See: Testing and Inspection/Scan Tool Testing and Procedures/Diagnostic Mode 04 - Erase DTC Memory
3. If the DTC memory was erased, generate readiness code. See: Testing and Inspection/Monitors, Trips, Drive Cycles and Readiness Codes
