wiring harness between G and yaw rate sensor connector C-36 terminals 4
and the body ground. Then go to Step 7.
NO: Repair or replace the damaged component(s). Then go to Step 7.
STEP 5. Check the battery.
Check the battery (Refer toBATTERY TEST
).
Q: Is the battery in good condition?
YES: Go to Step 6.
NO: Charge or replace the battery. Then go to Step 7.
STEP 6. Check the charging system.
Check the charging system (Refer to GENERATORS & REGULATORS
).
Q: Is the charging system in good condition?
YES: Replace the G and yaw rate sensor (Refer to G AND YAW RATE
SENSOR
). Then go to Step 7.
NO: Repair or replace the charging system component(s). Then go to Step
7.
STEP 7. Using scan tool MB991958, read the TCL/ASC diagnostic trouble
code.
1. Connect scan tool MB991958 to the data link connec
tor. CAUTION: To prevent damage to scan tool always turn the
ignition switch to "LOCK" (OFF) position before
connecting or disconnecting scan tool.

STARTER MOTOR DOES NOT STOPCheck the magnetic switch. ON-VEHICLE TESTING STARTER MOTOR DOES NOT OPERATE 1. Is the battery in good condition? If Yes, go to the next step. If No, then charge
or replace battery.
2. Disconnect the starter motor "S" (solenoid) terminal connector. Using a jumper
wire, apply battery positive voltage to starter motor "S" (solenoid) terminal.
Does starter motor operate normally? If Yes, then check ignition switch,
transmission range switch and the line between the battery and starter motor
"S" (solenoid) terminal. If No, then go to the next step.
3. Check if the cable between starter "B" (battery) terminal and battery positive
terminal for connection and continuity. Is the starter cable in good condition? I
f
Yes, then go to the next step. If No, then repair or replace the cable.
4. Check the connection and continuity of the cable between starter motor body
and the negative battery terminal. Is the ground line in good condition? If Yes,
then go to the next step. If No, then repair or replace cable.
5. Is the starter motor in good condition? If Yes, problem is excessive rotational
resistance of the engine. If No, then replace the starter motor.
BENCH TESTING MAGNETIC SWITCH PULL-IN TEST 1. Disconnect field coil wire from "M" terminal of the magnetic switch. See Fig.
3 . WARNING:Battery posts, terminals and related accessories
contain lead and lead compounds. Wash hands after
handling.
CAUTION: To prevent coil from burning, DO NOT apply voltage
to starter assembly for more than 10 seconds.
