Test | Result | Action | |
|---|---|---|---|
1 | Check cable and terminal integrity: - Engine ECM pin B33 - Engine ECM pin B22 - Engine ECM pin B11 - EMS relay pin 5 | OK | Proceed to test 2 |
Faulty | Rectify fault, proceed to test 7 | ||
2 | Check resistance value: Engine ECM pin A08 to - Engine ECM pin B33 (ignition coil 1) - Engine ECM pin B22 (ignition coil 2) - Engine ECM pin B11 (ignition coil 3) Engine ECM pin A21 to - Engine ECM pin B33 (ignition coil 1) - Engine ECM pin B22 (ignition coil 2) - Engine ECM pin B11 (ignition coil 3) | 3.0 Ohms to 4.2 Ohms | Proceed to test 3 |
Open circuit | Disconnect relevant ignition coil and proceed to test 4 | ||
Short circuit | Disconnect relevant ignition coil and proceed to test 5 | ||
3 | Check cable for short circuit: - Engine ECM pin B33 to ground - Engine ECM pin B22 to ground - Engine ECM pin B11 to ground | OK | Proceed to test 6 |
Short circuit | Locate and rectify wiring fault, proceed to test 6 | ||
4 | Check cable continuity: - EMS relay pin 5 to relevant ignition coil pin 2 - Engine ECM pin B33 to ignition coil 1 pin 1 - Engine ECM pin B22 to ignition coil 2 pin 1 - Engine ECM pin B11 to ignition coil 3 pin 1 | OK | Proceed to test 5 |
Open circuit | Locate and rectify wiring fault, proceed to test 6 | ||
5 | Check relevant ignition coil resistance: - Ignition coil pin 1 to ignition coil pin 2 | 3.0 Ohms to 4.2 Ohms | Proceed to test 6 |
Faulty | Renew relevant ignition coil, proceed to test 6 | ||
6 | Reconnect harness, clear fault code and run engine to verify fault cleared. | OK | Action complete - quit test |
Fault still present | Contact Triumph service | ||
