WARNING: This page is about a different car, the 1996 Saab 900. However, it is still accessible from the selected car via links, so may be relevant.
NOTE:
The Malfunction Indicator Light (MIL) on the instrument panel may also be referred to as CHECK ENGINE light. Inspect MIL to ensure it is operational and will come on if a DTC is stored.
- Turn ignition on with engine off. MIL should come on and remain on. If MIL does not come on, check bulb circuit on instrument panel and wiring circuit between MIL and ECM. The ECM is located in the engine compartment behind the partition on the left side. See appropriate wiring diagram in WIRING DIAGRAMS article.
- Start engine and ensure MIL goes off. If MIL remains on with engine running, a malfunction is detected. Proceed to RETRIEVING DIAGNOSTIC TROUBLE CODES (DTC).
