Ignition Timing Inspection
1. HDS DLC - Connect

NOTE: For specific operations, refer to the user's manual that came with the HDS. Make sure the HDS is loaded with the latest software.
1.
Turn the vehicle to the OFF (LOCK) mode.
3.
Turn the vehicle to the ON mode.
4.
Make sure the HDS communicates with the vehicle. If it does not communicate, go to the DLC circuit troubleshooting.


NOTE: If a DTC is present, diagnose and repair the cause before continuing with this inspection.

3. Engine - Warm Up
1.
Start the engine. Hold the engine speed at 3,000 rpm with no load (M/T in neutral, CVT in P or N) until the radiator fan comes on, then let it idle.

5. SCS - Short
1.
Turn the vehicle to the OFF (LOCK) mode.
2.
Jump the SCS line with the HDS.

6. Ignition Timing - Inspect
1.
Start the engine.
2.
Connect the timing light to the service loop (white tape).
3.
Aim the light toward the pointer (A) on the drive belt auto-tensioner bracket. Check the ignition timing under a no load condition (headlights, blower fan, rear window defogger, and air conditioner are turned off).
Ignition Timing
MT:
0 ±2 ° BTDC (WHITE mark (B)) at idle in Neutral
CVT:
0 ±2 ° BTDC (WHITE mark (B)) at idle in P or N
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.
