Fault Code | Possible cause | Action |
P1698 | Sensor supply circuit shorted Sensor supply circuit shorted to ground Sensor supply circuit shorted to battery positive | View & note 'sensor' data. Note ECM sensors requiring a power supply will not be active. Disconnect ECM and proceed to pinpoint test 1: |
Pinpoint Tests
Test | Result | Action |
1. Check cable and terminal integrity: ECM pin B01 ECM pin B20 | OK | Proceed to test 2 |
Faulty | Rectify fault, proceed to test 5 | |
2. Check cable for short circuit ECM pin B01 to ECM pin B20 | OK | Proceed to test 4 |
Faulty | Proceed to test 3 | |
3. Disconnect the following sensors in turn: MAP sensor Ambient pressure sensor Throttle position switch Exhaust control valve actuator Fall detection sensor and retest for short circuit ECM pin B01 to ECM pin B20 | OK | Replace sensor last removed and proceed to test 5 |
Faulty | Proceed to test 4 | |
4. Check cable for short circuit: ECM pin B01 to ground ECM pin B20 to ground ECM pin B01 to A06 ECM pin B20 to A06 ECM pin B01 to battery positive ECM pin B20 to battery positive | OK | Proceed to test 5 |
Short circuit | Locate and rectify wiring fault, proceed to test 5 | |
5. Reconnect harness, clear fault code and use service software to check for correct sensor outputs and 5V sensor supply voltage level | OK | Action complete - quit test |
