Remove the airbag module.
Attention! The SRS system is designed so that after the battery is disconnected, sufficient voltage is maintained for 30 seconds to deploy the airbag. Therefore, if work is performed on the SRS system immediately after disconnecting the battery, the unintentional deployment of the airbag may cause serious injury.

Troubleshooting Guide
If the engine crankshaft does not turn with the starter when the ignition key is in the «START», then determine if the starter interlock switch is (automatic transmission selector switch) pregnant «P» («PARK») or «N» («NEUTRAL»).
If start blocking (state «NO-CRANK») appears only in one of the positions of the automatic transmission selector lever, then most likely the reason is incorrect adjustment or a malfunction of the starter interlock switch.
Checking spark plugs
Connect the high voltage spark plug wire to the spark plug removed from the cylinder head.
Connect outer electrode (frame) candles with «weight» (with engine bracket) and turn the crankshaft of the engine with a starter.
Pic. 7.11. Spark plug defects
Make sure there is a spark between the spark plug electrodes (pic. 7.11).
Attention! When replacing a spark plug, the new spark plug must have a built-in resistor.
Checking high voltage spark plug wires
With the engine idling, disconnect the high voltage spark plug wires from the spark plugs one by one. Check for changes in engine performance.
Spray the high voltage secondary spark plug wire with water spray and check for voltage leaks if the spark plug wires are cracked.
Attention! Test with rubber gloves.
If there is no change in engine performance, then measure the resistance of the spark plug and check the spark plug itself.
Pic. 7.12. Checking the cap and insulation
Check the cap and insulation of the high voltage spark plug wire for cracks (pic. 7.12).
Measure the resistance of the high voltage spark plug wire.
For 2.7L engine
Note. The resistance of the high voltage spark plug wire should not exceed 10 kOhm per meter of wire length. If the wire resistance is higher than the specified value, then replace the wire.
