Diagnostic help

WARNING: This page is about a different car, the 2001 Saab 9-3. However, it is still accessible from the selected car via links, so may be relevant.

The control module output can be activated and the control module input from the switch can be read using the diagnostic tool.

If the indicator lamp lights on activation of the control module output, the fault probably lies between fuse B and pin 9 on TWICE.

If the indicator lamp does not light on activation of the control module output, the fault probably lies in the circuit from relay (511) to the heating pad (64RL/RR).
