Note the specific codes to identify the affected systems.

3. Resolve Identified Issues

A. Check Engine Light (CEL)

If a code related to emissions or engine performance is present:
1. Inspect air filters and replace if clogged.
2. Check spark plugs and replace if worn or fouled.
3. Examine fuel injectors for clogs and clean or replace as necessary.

B. ABS Warning Light

If ABS-related codes are present:
1. Inspect wheel speed sensors and clean or replace any that are damaged.
2. Check ABS module connections for corrosion or damage.

C. TPMS Warning Light

For TPMS issues:
1. Check each tire for proper inflation.
2. Use a TPMS tool to reset the system after adjustments.

D. Stability Assist and Oil Pressure Lights

For stability assist or oil pressure alerts:
1. Inspect related sensors and wiring for faults.
2. Verify oil levels and replace oil if necessary.

4. Reconnect Battery and Clear Codes

After repairs, reconnect the negative battery terminal.
Use the OBD-II scanner to clear any existing codes and reset the warning lights.
