Pinpoint Tests
Test | Result | Action |
1. Check cable and terminal integrity: ABS ECM connector pin 16 and Ground pin 24 | OK | Proceed to test 2 |
Faulty | Rectify fault, proceed to test 5 | |
2. Check cable continuity of the ABS ignition supply circuit: With Ignition 'ON', check voltage between ABS ECM connector pin 16 and Ground | Same as 'across battery' voltage | Proceed to test 3 |
Less than 'across battery' voltage | Locate and rectify wiring fault, proceed to test 5 | |
3. Check cable continuity of the ABS warning light circuit: Check voltage between: ABS ECM connector pin 21 and Ground | Voltage greater than 1.5 V | Proceed to test 4 |
Voltage less than 1.5 V | Locate and rectify fault, proceed to test 5 | |
4. Check cable continuity of the ABS warning light circuit: Short ABS ECM connector pin 21 and Ground pin 24 together: Turn Ignition 'ON' | ABS warning light 'OFF' | Proceed to test 5 |
ABS warning light 'ON' | Locate and rectify fault, proceed to test 5 | |
5. Reconnect ABS ECM harness, clear fault code and test ABS to verify fault cleared | OK | Action complete - quit test |
