Diagnostic Aids
WARNING: This page is about a different car, the 2006 Suzuki Reno and 2006 Suzuki Forenza. However, it is still accessible from the selected car via links, so may be relevant.
Whenever this diagnostic reports the system has passed, or if the battery is disconnected, the diagnostic must fail on consecutive tries before setting a DTC. The initial failure is not reported to the diagnostic executive or displayed on a scan tool. A passing system always reports to the diagnostic executive immediately. Check for the following conditions:
- Missing or damaged O-rings at fuel vapor and EVAP emission purge line canister fittings
- Cracked or punctured EVAP emission canister
- Damaged source vacuum line, EVAP emission purge line, EVAP emission vent hose or fuel tank vapor line.
- Poor connection at ECM. Inspect harness connectors for the following conditions:
- Backed-out terminals
- Improper mating
- Broken locks
- Improperly formed
- Damaged terminals
- Poor terminal-to-wire connection
- Damaged harness. Inspect the wiring harness to the EVAP emission vent solenoid, EVAP emission canister purge valve and the fuel tank pressure sensor for an intermittent open or short circuit.
