ADVANCE/RETARD TIMING CONTROL CHECKS
Advance and retard timing controls ensure that ignition occurs at the proper
time during the compres-sion stroke. These controls include mechanical
advance, vacuum advance, vacuum retard, electronic advance, electronic retard,
and e lectronic advance/retard. Depending on make and model, a vehicle may be
equipped with a single timing control device, or two or more devices may be
used in combination.
NOTE: Advance and retard timing test procedures vary widely from vehicle
to vehicle. The following paragraphs provide general test procedures for
checking mechanical advance, mechanical/vacuum advance, and vacuum retard.
ALWAYS make sure initial timing and dwell are correct before checking
advance/retard tin1ing. ALWAYS refer to the service manual for the vehicle
under test to obtain the proper timing procedures and spedfications. OBSERVE
ALL SAFETY PRECAUTIONS.
Centrifugal/Mechanical Advance
- Make sure timing light is properly connected as described in TIMING LIGHT CONNECTION.
- Make sure initial timing is correct. If necessary, prepare engine for advance timing check as directed by manufacturer’s instructions.
- a. With timing light directed at timing marks, note position of rotating timing mark in relation to reference pointer. Reading should indicate initial timing in accordance with manufacturer’s specifications.
- b. Adjust engine speed to the specified RPM for advance test.
- c. Press Fw1ction (F) switch as needed to select advance mode. The ADVANCE indicator and Advance Degree symbol will display when advance mode is selected. T he LCD display will show “Q” degrees advance and engine rpm.
- d . With timing light directed at timing marks, press Cylinder/Advance Increment switch as needed to reaJign timing marks to initial timing or as instructed by manufacturer’s specifications. Note degrees advance on LCD display and compare with manufacturer’s s pecifications.
- e. Turn off ignition and disconnect timing light from engine.
Vacuum Advance
- Make sure timing light is properly connected as described in TIMING LIGHT CONNECTION.

- b. Connect vacuum pump to dis tributor’s vacuum advance port.
- c . Start and r un engine until it r eaches normal operating temperature.
- d . Press Function (F ) switch as needed to select advance mode. The ADVANCE indicator a nd Advance Degree symbol will display w h e n advance mode is selec t e d . The LCD display will show “Q” degrees advance and engine rpm.
- e. With timing light directed at timing marks, note pos ition of rotating timing mark in relation to reference pointer. R eading should indicate initial timing in accordance with manufacturer’s specifications.
- f. Using vacuum pump, a pply specified amount of vacuum to distributor’s vacuum port.
- g. With timing light directed at timing marks, press Cylinder/Advance Increment switch as needed to realign timing marks to initial tinting. Note degr ees advance on LCD display and compare with manufacturer’s specifications.
- h. Turn off ignition and disconnect timing light from engine. Unplug and reconnect vacuum hose to distributor’s vacuum port .
Electronic Advance/Retard
Refer to manufacturer’s instructions for procedures to check electronic
advance/retard. For some systems, it may be necessary to set the timing
light’s advance display to “O” and to read timing from the vehicle’s timing
marks.
TIMING ADJUSTMENT
Refer to the vehicle’s service manual for procedures to adjust timing. DO
NOT ATTEMPT TO ADJUST T IMI G WITHOUT MA UFACTU RER’S SPECIFICATIONS.
TROUBLESHOOTING
NOTE: I f the timing light readout becomes inoperative or locks up during
use, disconnect and reconnect the timing light’s positive battery damp from
the battery to reset the unit.
If the timing light fails to operate, make t he following checks:
- a. Make s ure the battery clips are firmly connected to th e battery terminals.
- b. Make sure the battery clip polarity is correct (red clip to positive terminal, black clip to negative terminal).
- c. Ma ke sure the upper and lower ferrite cores of the inductive p ickup clip are clean. C lean the inductive pickup clip if necessary (re fer to Ch a pter 3).
- d. Make sure the inductive pickup clip is properly connected to the No. 1 spark plug cable.
- e. Make sure the No. l spark plug is working properly:
- Conn ect the inductive pickup clip to another spark plug cable.
- If the timing light flashes, service the No. 1 spark plug before continuing.
CLEANING THE INDUCTIVE PICKUP CLIP
Dirt or grease on the inside surfaces of the inductive pickup clip can result
in erratic flashing or poor operation of t he timing light. Periodically clean
the contact surfaces ins ide the inductive pickup clip by wiping with a soft
cloth.
REPLACING THE INDUCTIVE PICKUP LEADS
The timing light is equipped with detachable leads which can be disconnected
from t h e timing light for easy storage after use. If the test leads or clips
become damaged, a replacement set can be obtained from your dealer or dfrectly
from the service r:P.ntP.r.
Safety Precautions
Always observe safety precautions whenever working on a vehicle. DO NOT wear loose clothing, watches, rings or other jewelry when working on a vehicle. Always wear safety eye protection. Only work on a vehicle in a well-ventilated area. Put transmission in “park” (for automatic) or “neutral” (for manual) . Set parking brake. Put blocks on drive wheels . Avoid moving fan blades or a ny potentially moving parts. WHEN USING THE TIMING LIGHT, THESE PARTS MAY APPEAR TO BE STOPPED OR MOVING SLOWLY. Avoid hot engine parts. The vehicle battery produces explosive gases. DO NOT smoke or allow spark or flame near the battery. BE CAREFUL when working near high-voltage parts (spark plugs or coil terminals) . Turn off ignition before connecting (or disconnecting) any testing equipment. ALWAYS READ THE VEHICLE’S SERVICE MANUAL BEFORE PERFORMING ANY PROCEDURE. OBSERVE ALL SAFETY PRECAUTIONS.
