   3. Aim the light toward the pointer (A) on the cam chain case. Check the ignition timing under a no load condition (headlights, blower fan, rear window defogger, and air conditioner are turned off). 4. If the ignition timing differs from the specification, check the camshaft timing . If the camshaft timing is OK, update the PCM if it does not have the latest software , or substitute a known-good PCM , then recheck. If the system works properly, and the PCM was substituted, replace the original PCM . 5. Disconnect the HDS and the timing light.
